116-516: E-470 is a 47-mile-long (76 km) controlled-access toll road that traverses the eastern portion of the Denver metropolitan area in the US state of Colorado . It is the eastern half of the 470 beltway that serves Meridian , Parker , Aurora , Denver International Airport , and Brighton . The toll road is neither a state highway nor an Interstate Highway and is instead owned and maintained by
232-663: A dual highway ) in 1932 between Cologne and Bonn . It then rapidly constructed the first nationwide system of such roads. The first North American freeways (known as parkways) opened in the New York City area in the 1920s. Britain, heavily influenced by the railways, did not build its first motorway , the Preston By-pass ( M6 ), until 1958. Most technologically advanced nations feature an extensive network of freeways or motorways to provide high-capacity urban travel, or high-speed rural travel, or both. Many have
348-466: A median separates the opposite directions of traffic. This strip may be as simple as a grassy area, or may include a crash barrier such as a " Jersey barrier " or an "Ontario Tall Wall" to prevent head-on collisions . On some freeways, the two carriageways are built on different alignments; this may be done to make use of available corridors in a mountainous area or to provide narrower corridors through dense urban areas . Control of access relates to
464-707: A cloverleaf and trumpet interchange when it opened in 1937, and until the Second World War , boasted the longest illuminated stretch of roadway built. A decade later, the first section of Highway 401 was opened, based on earlier designs. It has since gone on to become the busiest highway in the world. The word freeway was first used in February 1930 by Edward M. Bassett . Bassett argued that roads should be classified into three basic types: highways, parkways , and freeways. In Bassett's zoning and property law -based system, abutting property owners have
580-607: A comprehensive study to evaluate the feasibility of introducing congestion pricing. The charge would be combined with other traffic reduction implementations, allowing money to be raised for public transit improvements and bike and pedestrian enhancements. The various pricing scenarios considered were presented in public meetings in December 2008, with final study results expected in 2009. (see San Francisco congestion pricing ) Taiwan Highway Electronic Toll Collection System (see Electronic Toll Collection (Taiwan) ) In December 2013,
696-507: A declining-balance account, which is debited each time they pass a toll point. Electronic toll lanes may operate alongside conventional toll booths so that drivers who do not have transponders can pay at the booth. Open road tolling is an increasingly popular alternative which eliminates toll booths altogether; electronic readers mounted beside or over the road read the transponders as vehicles pass at highway speeds, eliminating traffic bottlenecks created by vehicles slowing down to go through
812-401: A fly-by interchange. The highway continues north, passing west of Denver International Airport and interchanging with Peña Boulevard at a full cloverleaf interchange to provide travelers access to the airport from the tollway. E-470 then continues north and then turns to the west, entering the outskirts of Brighton and interchanging with I-76 and then U.S. Highway 85 (US 85) near
928-620: A freeway, specialized pedestrian footbridges or tunnels may also be provided. These structures enable pedestrians and cyclists to cross the freeway at that point without a detour to the nearest road crossing. Access to freeways is typically provided only at grade-separated interchanges , though lower-standard right-in/right-out (left-in/left-out in countries that drive on the left) access can be used for direct connections to side roads. In many cases, sophisticated interchanges allow for smooth, uninterrupted transitions between intersecting freeways and busy arterial roads . However, sometimes it
1044-554: A full outer beltway for the Denver metropolitan area proposed by CDOT in the 1960s. After the completion of SH 470 , plans for the eastern extension gained momentum in the 1980s, as Denver moved forward with plans for a new international airport in its corridor. Recognizing the highway's development potential, a number of local governments joined together to create the E-470 Public Highway Authority,
1160-441: A large amount of information in both directions between the road and the vehicle, but also of providing route information. Thus, ETC 2.0 has far more advanced functions than ETC 8 (which provides only toll collection function on toll roads). The ETC 2.0 system provides a variety of advantages to road users through information provision services, such as congestion avoidance, safe driving support, etc., and route information collected by
1276-597: A largely undeveloped area. With the opening of Denver International Airport in 1995, E-470 came in as a direct route to the airport from the rapidly growing southern tier of the metropolitan area. Upon its completion, the highway provided the same access for northern Colorado, itself a high-growth area. However, perhaps the most significant growth in the region will occur in the E-470 corridor itself, which spawned numerous annexations by member cities; Commerce City has doubled in land area in anticipation of this new development. In
SECTION 10
#17327910744491392-434: A larger number of guide signs than other roads, and the signs themselves are physically larger. Guide signs are often mounted on overpasses or overhead gantries so that drivers can see where each lane goes. Exit numbers are commonly derived from the exit's distance in miles or kilometers from the start of the freeway. In some areas, there are public rest areas or service areas on freeways, as well as emergency phones on
1508-499: A legal status which limits the types of vehicles that can use a highway, as well as a road design that limits the points at which they can access it. Major arterial roads will often have partial access control , meaning that side roads will intersect the main road at grade, instead of using interchanges, but driveways may not connect directly to the main road, and drivers must use intersecting roads to access adjacent land. At arterial junctions with relatively quiet side roads, traffic
1624-527: A milepost system but does not use milepost markers. In Europe and some other countries, motorways typically have similar characteristics such as: Two-lane freeways , often undivided, are sometimes built when traffic volumes are low or right-of-way is limited; they may be designed for easy conversion to one side of a four-lane freeway. (For example, most of the Bert T. Combs Mountain Parkway in eastern Kentucky
1740-447: A motorway is understood as a public road with dual carriageways and at least two lanes each way. All entrances and exits are signposted and all interchanges are grade separated. Central barrier or median present throughout the road. No crossing is permitted, while stopping is permitted only in an emergency. Restricted access to motor vehicles, prohibited to pedestrians, animals, pedal cycles, mopeds, agricultural vehicles. The minimum speed
1856-777: A national-level or even international-level (e.g. European E route ) system of route numbering . There are several international standards that give some definitions of words such as motorways, but there is no formal definition of the English language words such as freeway , motorway , and expressway , or of the equivalent words in other languages such as autoroute , Autobahn , autostrada , autocesta, autoput , that are accepted worldwide—in most cases these words are defined by local statute or design standards or regional international treaties. Descriptions that are widely used include: One green or blue symbol (like [REDACTED] ) appears at motorway entry in countries that follow
1972-600: A number of patterns. The actual pattern is determined by a number of factors including local topology, traffic density, land cost, building costs, type of road, etc. In some jurisdictions feeder/distributor lanes are common, especially for cloverleaf interchanges ; in others, such as the United Kingdom, where the roundabout interchange is common, feeder/distributor lanes are seldom seen. Motorways in Europe typically differ between exits and junctions. An exit leads out of
2088-624: A park and where intersecting streets crossed over bridges. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened 1931) and the contiguous Grand Central Parkway (opened 1936). In Germany, construction of the Bonn-Cologne Autobahn began in 1929 and was opened in 1932 by Konrad Adenauer , then
2204-730: A payment at chain convenient store at third day after vehicle travel, since a subscription to ETC is not mandated by law. Taiwan was the first country to transfer from flat-rate toll stations to a distance-based pay-as-you-go tolling system on all of its freeways. It has the longest ETC freeway mileage in the world. Electronic toll collection systems rely on four major components: automated vehicle identification, automated vehicle classification, transaction processing, and violation enforcement. The four components are somewhat independent, and, in fact, some toll agencies have contracted out functions separately. In some cases, this division of functions has resulted in difficulties. In one notable example,
2320-655: A prepaid M-TAG account. The European Union issued the EFC-directive, which attempts to standardize European toll collection systems. Systems deployed after January 1, 2007 must support at least one of the following technologies: satellite positioning, mobile communications using the GSM-GPRS standard or 5.8 GHz microwave technology. Furthermore, the European Commission issued the Regulation on
2436-457: A private venture, was the world's first limited-access roadway. It included many modern features, including banked turns , guard rails and reinforced concrete tarmac . Traffic could turn left between the parkway and connectors, crossing oncoming traffic, so it was not a controlled-access highway (or "freeway" as later defined by the federal government's Manual on Uniform Traffic Control Devices ). Modern controlled-access highways originated in
SECTION 20
#17327910744492552-575: A quasi-governmental entity that would construct the highway. In 1987, the Public Highway Authority Law was passed by the Colorado State Legislature , giving the E-470 Public Highway Authority the power to do everything needed to plan, design, finance, construct, and operate the toll highway. The highway would be financed through tolls, a relative rarity in the western US. The first section, between I-25 in
2668-609: A reduction in deaths in a range from 20% to 50% on those sections. Speed, in Europe, is considered to be one of the main contributory factors to collisions. Some countries, such as France and Switzerland, have achieved a death reduction by a better monitoring of speed. Tools used for monitoring speed might be an increase in traffic density; improved speed enforcement and stricter regulation leading to driver license withdrawal; safety cameras; penalty point; and higher fines. Some other countries use automatic time-over-distance cameras (also known as section controls ) to manage speed. Fatigue
2784-493: A separate roadway or altogether eliminates it. In some parts of the world, notably parts of the US , frontage roads form an integral part of the freeway system. These parallel surface roads provide a transition between high-speed "through" traffic and local traffic. Frequent slip-ramps provide access between the freeway and the frontage road, which in turn provides direct access to local roads and businesses. Except on some two-lane freeways (and very rarely on wider freeways),
2900-510: A similar system of express and local lanes for a maximum width of 21 lanes on a 2-mile (3.2 km) segment between Interstate 805 and California State Route 56 . In Mississauga , Ontario, Highway 401 uses collector-express lanes for a total of 18 lanes through its intersection with Highway 403 / Highway 410 and Highway 427 . These wide freeways may use separate collector and express lanes to separate through traffic from local traffic, or special high-occupancy vehicle lanes , either as
3016-411: A special restriction on the innermost lane or a separate roadway, to encourage carpooling . These HOV lanes , or roadways open to all traffic, can be reversible lanes , providing more capacity in the direction of heavy traffic, and reversing direction before traffic switches. Sometimes a collector/distributor road , a shorter version of a local lane, shifts weaving between closely spaced interchanges to
3132-451: A toll booth lane. Vehicles without transponders are either excluded or pay by plate – a license plate reader takes a picture of the license plate to identify the vehicle, and a bill may be mailed to the address where the car's license plate number is registered, or drivers may have a certain amount of time to pay online or by phone. Singapore was the first city in the world to implement an electronic road toll collection system known as
3248-551: A vehicle on another operator's tolled road with the tolls incurred charged to the driver's toll-payment account with their home operator. An example is the United States E-ZPass tag, which is accepted on toll roads, bridges and tunnels in fifteen states from Illinois to Maine . In Australia, there are a number or organizations that provide tags known as e-TAG that can be used on toll roads. They include Transport for NSW 's E-Toll and Transurban 's Linkt . A toll
3364-418: Is a faster alternative which is replacing toll booths , where vehicles must stop and the driver manually pays the toll with cash or a card. In most systems, vehicles using the system are equipped with an automated radio transponder device. When the vehicle passes a roadside toll reader device, a radio signal from the reader triggers the transponder, which transmits back an identifying number which registers
3480-442: Is a truck tolling system in (Germany). This system instead uses Global Positioning System location information to identify when a vehicle is located on a tolled Autobahn . Implementation of this system turned out to be far lengthier and more costly than expected. As smart phone use becomes more commonplace, some toll road management companies have turned to mobile phone apps to inexpensively automate and expedite paying tolls from
3596-453: Is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway , motorway , and expressway . Other similar terms include throughway or thruway and parkway . Some of these may be limited-access highways , although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following

3712-507: Is accepted on all toll roads in the country. In Brazil, the Sem Parar/Via-Fácil system allows customers to pass through tolls in more than 1,000 lanes in the states of São Paulo, Paraná, Rio Grande do Sul, Santa Catarina, Bahia and Rio de Janeiro. Sem Parar/Via-Fácil also allows users to enter and exit more than 100 parking lots. There are also other systems, such as via expressa, onda livre and auto expresso, that are present in
3828-409: Is accomplished by a combination of a camera which takes a picture of the car and a radio frequency keyed computer which searches for a drivers window/bumper mounted transponder to verify and collect payment. The system sends a notice and fine to cars that pass through without having an active account or paying a toll. Factors hindering full-speed electronic collection include: Even if line lengths are

In 1995, Portugal became the first country to apply a single, universal system to all tolls in the country, the Via Verde , which can also be used in parking lots and gas stations. The United States is another country with widespread use of ETC in several states, though many U.S. toll roads maintain the option of manual collection. ETC 2.0 is not only capable of sending and receiving
4060-545: Is considered as a risk factor more specific to monotonous roads such as motorways, although such data are not monitored/recorded in many countries. According to Vinci Autoroutes , one third of accidents in French motorways are due to sleepy driving. Electronic toll collection Electronic toll collection ( ETC ) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads , HOV lanes , toll bridges , and toll tunnels . It
4176-735: Is controlled mainly by two-way stop signs which do not impose significant interruptions on traffic using the main highway. Roundabouts are often used at busier intersections in Europe because they help minimize interruptions in flow, while traffic signals that create greater interference with traffic are still preferred in North America. There may be occasional interchanges with other major arterial roads. Examples include US 23 between SR 15 's eastern terminus and Delaware, Ohio , along with SR 15 between its eastern terminus and I-75 , US 30 , SR 29 / US 33 , and US 35 in western and central Ohio. This type of road
4292-483: Is debited to the customer's account with their tag provider. Some toll road operators – including Sydney's Sydney Harbour Tunnel , Lane Cove Tunnel and Westlink M7 , Melbourne's CityLink and Eastlink , and Brisbane's Gateway Motorway – encourage use of such tags, and apply an additional vehicle matching fee to vehicles without a tag. A similar device in France, called Liber-T for light vehicles and TIS-PL for HGVs,
4408-404: Is in the urban context of congested cities, allowing to charge tolls without vehicles having to slow down. This application made feasible to concession to the private sector the construction and operation of urban freeways, as well as the introduction or improvement of congestion pricing , as a policy to restrict auto travel in downtown areas. Between 2004 and 2005, Santiago, Chile , implemented

One example in the United States (notorious for the resulting congestion) is the connection from Interstate 70 to the Pennsylvania Turnpike ( Interstate 70 and Interstate 76 ) through the town of Breezewood, Pennsylvania . Speed limits are generally higher on freeways and are occasionally nonexistent (as on much of Germany's Autobahn network). Because higher speeds reduce decision time, freeways are usually equipped with
4640-450: Is not lower than 50 km/h [31 mph] and the maximum speed is not higher than 130 km/h [81 mph] (except Germany where no speed limit is defined). Motorways are designed to carry heavy traffic at high speed with the lowest possible number of accidents. They are also designed to collect long-distance traffic from other roads, so that conflicts between long-distance traffic and local traffic are avoided. According to

4872-407: Is sometimes called an expressway . Freeways are usually limited to motor vehicles of a minimum power or weight; signs may prohibit cyclists , pedestrians and equestrians and impose a minimum speed. It is possible for non-motorized traffic to use facilities within the same right-of-way, such as sidewalks constructed along freeway-standard bridges and multi-use paths next to freeways such as

However, the respective national definitions and the type of roads covered may present slight differences in different EU countries. The first version of modern controlled-access highways evolved during the first half of the 20th century. The Long Island Motor Parkway on Long Island , New York , opened in 1908 as
5104-408: Is sufficient to make the no-stop-to-pay savings insignificant compared to time still lost due waiting in line to pass the toll gate. Toll plazas are typically wider than the rest of the highway; reducing the need for them makes it possible to fit toll roads into tight corridors. Despite these limitations, if delay at the toll gate is reduced, the tollbooth can serve more vehicles per hour. The greater
5220-575: Is the process of determining the identity of a vehicle subject to tolls. The majority of toll facilities record the passage of vehicles through a limited number of toll gates. At such facilities, the task is then to identify the vehicle in the gate area. Some early AVI systems used barcodes affixed to each vehicle, to be read optically at the toll booth. Optical systems proved to have poor reading reliability, especially when faced with inclement weather and dirty vehicles. Most current AVI systems rely on radio-frequency identification , where an antenna at

Different states of the United States have different laws. Cycling on freeways in Arizona may be prohibited only where there is an alternative route judged equal or better for cycling. Wyoming , the second least densely populated state, allows cycling on all freeways. Oregon allows bicycles except on specific urban freeways in Portland and Medford . In countries such as

8468-520: The distance traveled on the tolled road network - without the use of any roadside infrastructure. US Nobel Economics Prize winner William Vickrey was the first to propose a system of electronic tolling for the Washington Metropolitan Area in 1959. In the 1960s and the 1970s, the first prototype systems were tested. Norway has been a world pioneer in the widespread implementation of this technology, beginning in 1986. Italy
8584-517: The early 1920s in response to the rapidly increasing use of the automobile , the demand for faster movement between cities and as a consequence of improvements in paving processes, techniques and materials. These original high-speed roads were referred to as " dual highways " and have been modernized and are still in use today. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. The Autostrada dei Laghi ("Lakes Motorway"),
8700-707: The east. The tollway begins at the I-25/ State Highway ;470 (SH 470, C-470) interchange in Lone Tree and runs east through the unincorporated community of Meridian and south of the Centennial Airport . It then passes through the north side of Parker, interchanging with SH 83 (Parker Road) before continuing east to Southlands, an outdoor mall in southeast Aurora. It then turns north through Aurora, passing east of Buckley Space Force Base before interchanging with I-70 , forming
8816-461: The end of the journey. Dr. Eng. Mario Alvisi is considered the father of ETC in motorways because not only co-designed Telepass but was able to make it the first standardized operating ETC system in the world as European standard in 1996. He acted as a consultant for deployment of ETC in many countries including Japan, United States, Brazil. In Japan, only the ETC System was constructed in all of
8932-485: The first built in the world, connecting Milan to Lake Como and Lake Maggiore , and now parts of the A8 and A9 motorways, was devised by Piero Puricelli and was inaugurated in 1924. This motorway, called autostrada , contained only one lane in each direction and no interchanges. The Bronx River Parkway was the first road in North America to utilize a median strip to separate the opposing lanes, to be constructed through
9048-412: The first half of the 20th century. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. Italy opened its first autostrada in 1924, A8 , connecting Milan to Varese . Germany began to build its first controlled-access autobahn without speed limits (30 kilometres [19 mi] on what is now A555 , then referred to as
9164-445: The front and rear license plate of each vehicle. A bill is mailed after approximately 30 days to the registered owner of the vehicle in accordance with state law. Rental car companies at Denver International Airport have been accused of overcharging unwitting visitors for unpaid tolls because of the road's cashless collection system. E-470 is the eastern portion of what was originally planned as Interstate 470 ( I-470 ),
9280-420: The gaps between vehicles, to provide basic information on the presence of a vehicle. With clever software processing of the inductive data a wide range of vehicle classes can be derived by careful analysis of the inductive profile. Treadles permit counting the number of axles as a vehicle passes over them and, with offset-treadle installations, also detect dual-tire vehicles. Light-curtain laser profilers record
9396-504: The highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials and collector roads . On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass. Elimination of conflicts with other directions of traffic dramatically improves safety, while increasing traffic capacity and speed. Controlled-access highways evolved during
9512-435: The highway into segments, each having a price value determined by distance to the next gate (interchange). A daily gate count is calculated at midnight, and the total charge is deducted in 48 hours. Each vehicle receives a further discount after the first 200 kilometers, and eTag subscribers with prepaid accounts get a further 10% reduction. Non-subscribers are billed by license plate recognition and mail statements, or can make
9628-519: The lanes. One such example application is Alabama Freedom Pass mobile, used to link customer accounts at sites operated by American Roads LLC. The app communicates in real time with the facility transaction processing system to identify and debit customer accounts or bill a major credit card. Source: Automated vehicle classification is closely related to automated vehicle identification (AVI). Most toll facilities charge different rates for different types of vehicles, making it necessary to distinguish
9744-450: The long term, the greater the relative advantage that registering and turning one's vehicle into an electronic-toll one provides, the faster cars will be converted from manual-toll use to electronic-toll use, and therefore the fewer manual-toll cars will drag down average speed and thus capacity. In some countries, some toll agencies that use similar technology have set up (or are setting up) reciprocity arrangements, which permit one to drive
9860-469: The mayor of Cologne . The German Autobahn became the first nationwide highway system. In Canada , the first precursor with semi-controlled access was The Middle Road between Hamilton and Toronto , which featured a median divider between opposing traffic flow, as well as the nation's first cloverleaf interchange . This highway developed into the Queen Elizabeth Way , which featured
9976-400: The motorway system, whilst a junction is a crossing between motorways or a split/merge of two motorways. The motorway rules end at exits, but not at junctions. However, on some bridges, motorways, without changing appearance, temporarily end between the two exits closest to the bridge (or tunnel), and continue as dual carriageways . This is in order to give slower vehicles a possibility to use
10092-497: The need for transponders, some systems, notably the 407 ETR (Express Toll Route) near Toronto and the A282 ( M25 ) Dartford Crossing in the United Kingdom, use automatic number plate recognition. Here, a system of cameras captures images of vehicles passing through tolled areas, and the image of the number plate is extracted and used to identify the vehicle. This allows customers to use the facility without any advance interaction with
10208-563: The non-discounted passenger car toll to pass each mainline station is either $ 4.15 or $ 4.50; the discounted rates are $ 2.70 or $ 2.95. Drivers with ExpressToll accounts, E-470's automated toll collection service, and transponders mounted on their vehicle save 20 percent on posted toll rates along E-470. The toll stations no longer accept cash; E-470 was one of the first highways in the US to implement full highway-speed electronic tolling . Regarding License Plate Toll (for vehicles without ExpressToll transponders), cameras at each station photograph
10324-399: The old toll stations were replaced by distance-based pay-as-you-go all-electronic toll collection on all of Taiwan's major freeways. All tolls are collected electronically by overhead gantries with multi-lane free flow, not at traditional toll booths. Taiwan was the first country to switch from manual tolling to all-electronic, multi-lane free-flow tolling on all of its freeways. To simulate
10440-439: The other. Other methods involve constructing a service drive that shortens the long driveways (typically by less than 100 metres (330 ft)). An interchange or a junction is a highway layout that permits traffic from one controlled-access highway to access another and vice versa, whereas an access point is a highway layout where traffic from a distributor or local road can join a controlled-access highway. Some countries, such as
10556-444: The previous model, where a vehicle would not pass toll collection over short-distance travel, each vehicle receives 20 kilometers per diem of free travel and is billed NT$ 1.2 per kilometer thereafter. Buses and trailers are subject to heavy vehicle surcharges. The highway administration may alter fares (e.g. remove the per diem ) during peak travel seasons to facilitate distribution of congestion to midnight hours. The toll gates divide
10672-477: The rate is higher than the risk on urban roads. Speeds are higher on rural roads and autobahns than urban roads, increasing the severity potential of a crash. According to ETSC, German motorways without a speed limit, but with a 130 km/h (81 mph) speed recommendation, are 25% more deadly than motorways with a speed limit. Germany also introduced some 130 km/h (81 mph) speed limits on various motorway sections that were not limited. This generated
10788-643: The rights of light , air and access to highways, but not parkways and freeways; the latter two are distinguished in that the purpose of a parkway is recreation, while the purpose of a freeway is movement. Thus, as originally conceived, a freeway is simply a strip of public land devoted to movement to which abutting property owners do not have rights of light, air or access. Freeways, by definition, have no at-grade intersections with other roads, railroads or multi-use trails . Therefore, no traffic signals are needed and through traffic on freeways does not normally need to stop at traffic signals. Some countries, such as
10904-487: The road side devices and greatly contribute to ITS promotion. As of March 2018, in Japan, a total of approximately 2.61 million vehicles are equipped with devices compliant with the ETC 2.0. In some urban settings, automated gates are in use in electronic-toll lanes, with 5 mph (8 km/h) legal limits on speed; in other settings, 20 mph (35 km/h) legal limits are not uncommon. However, in other areas such as
11020-409: The same in electronic lanes as in manual ones, electronic tolls save registered cars time: eliminating the stop at a window or toll machine, between successive cars passing the collection machine, means a fixed-length stretch of their journey past it is traveled at a higher average speed, and in a lower time. This is at least a psychological improvement, even if the length of the lines in automated lanes
11136-421: The shape of the vehicle, which can help distinguish trucks and trailers. In modern systems simple laser light curtains are being replaced with more technically advanced Lidar systems. These safety critical systems, used in autonomous vehicles, are less sensitive to environmental conditions. Source: Transaction processing deals with maintaining customer accounts, posting toll transactions and customer payments to
11252-432: The side of a divided highway that has a lot of private access on one side and sometimes has long driveways on the other side since an easement for widening comes into place, especially in rural areas. When a third carriageway is added, sometimes it can shift a directional carriageway by 20–60 metres (50–200 ft) (or maybe more depending on land availability) as a way to retain private access on one side that favors over
11368-578: The signalized interchange, except for northbound E-470 to westbound I-70 traffic, which uses a flyover ramp. The I-70/E-470 Fly-By Interchange Complex in Aurora was recognized by the Design Build Institute of America (DBIA) with a National Design Build Award in 2008. In November 2014, an additional interchange opened at Quebec Street in Thornton. In April 2016, E-470 started construction work to widen an eight-mile (13 km) stretch of
11484-542: The south and Parker Road in Douglas County, opened to traffic June 1, 1991. Tolling began on July 15, making E-470 the first highway in the US to implement open road electronic tolling. The highway was opened segment by segment until the final stretch connecting to I-25 in the north in Adams County opened on January 3, 2003. In its early years, traffic was light as the completed portion was short and traversed
11600-422: The states of Rio de Janeiro, Rio Grande do Sul, Santa Catarina, Parana and Minas Gerais. Since 2016, National Highway Authority of Pakistan implemented electronic toll collection on its motorway network using a RFID -based tag called the "M-TAG". The tag is attached to the windscreen of vehicles and is automatically scanned at toll plazas on entry and exit, meanwhile debiting the calculated toll tax from
11716-423: The throughput of any toll lane, the fewer lanes required, so construction costs can be reduced. Specifically, the toll-collecting authorities have incentives to resist pressure to limit the fraction of electronic lanes in order to limit the length of manual-lane lines. In the short term, the greater the fraction of automated lanes, the lower the cost of operation (once the capital costs of automating are amortized). In
11832-479: The toll agency. The disadvantage is that fully automatic recognition has a significant error rate, leading to billing errors and the cost of transaction processing (which requires locating and corresponding with the customer) can be significant. Systems that incorporate a manual review stage have much lower error rates, but require a continuing staffing expense. A few toll facilities cover a very wide area, making fixed toll gates impractical. The most notable of these
11948-416: The toll gate communicates with a transponder on the vehicle via Dedicated Short Range Communications (DSRC). RFID tags have proved to have excellent accuracy, and can be read at highway speeds. The major disadvantage is the cost of equipping each vehicle with a transponder, which can be a major start-up expense, if paid by the toll agency, or a strong customer deterrent, if paid by the customer. To avoid
12064-483: The toll road to three lanes in each direction between Parker Road and Quincy Avenue in southeastern Aurora. The $ 90-million (equivalent to $ 110 million in 2023) project was completed December 2017. According to the 2015 E-470 Annual Report (page 3), "The widening is being constructed now to get ahead of the curve on future traffic volume, which has had double-digit growth in each of the past three years." Controlled-access highway A controlled-access highway
12180-561: The town of Parker. In addition to all of these jurisdictions, E-470 also passes through the city and county of Denver near Denver International Airport . Affiliate, nonvoting members of the Authority, which the highway does not directly serve, are the cities of Arvada , Lone Tree , and Greeley ; Weld County ; and the city and county of Broomfield . Ex officio members are the Colorado Department of Transportation (CDOT),
12296-425: The unincorporated community of Henderson before reaching the northern end at the interchange with I-25, where the toll road continues west as Northwest Parkway north of Thornton . The quasi-government entity that manages the highway, the E-470 Public Highway Authority, consists of eight member jurisdictions: Adams, Arapahoe, and Douglas counties and the cities of Aurora, Brighton, Commerce City , and Thornton and
12412-586: The vehicle's use of the road, and an electronic payment system charges the user the toll. A major advantage is the driver does not have to stop, reducing traffic delays. Electronic tolling is cheaper than a staffed toll booth, reducing transaction costs for government or private road owners. The ease of varying the amount of the toll makes it easy to implement road congestion pricing , including for high-occupancy lanes, toll lanes that bypass congestion, and city-wide congestion charges. The payment system usually requires users to sign up in advance and load money into
12528-453: The vehicles passing through the toll facility. The simplest method is to store the vehicle class in the customer record, and use the AVI data to look up the vehicle class. This is low-cost, but limits user flexibility, in such cases as the automobile owner who occasionally tows a trailer. More complex systems use a variety of sensors. Inductive sensors embedded in the road surface can determine
12644-444: The windshield, with readers located in overhead gantries. After tests in 1974, in 1975, Singapore became the first country in the world to implement an electronic road toll collection system known as the Singapore Area Licensing Scheme for purposes of congestion pricing on its more urbanized roads. It was refined in 1998 as Electronic Road Pricing (ERP). Italy deployed a full ETC in motorways at national scale in 1989. Telepass ,
12760-471: The world's first 100% full speed electronic tolling with transponders crossing through the city's core (CBD) in a system of several concessioned urban freeways ( Autopista Central and Autopista ). The United Arab Emirates implemented in 2007 a similar road toll collection in Dubai , called Salik . Similar schemes were previously implemented but only on bypass or outer ring urban freeways in several cities around
12876-485: The world's first successful congestion pricing scheme implemented with manual control (see also Singapore's Area Licensing Scheme ), and was refined in 1998 (see Singapore's Electronic Road Pricing ), Bergen (1986), Oslo (1990), and Trondheim (1991) (see Trondheim Toll Scheme ); Rome in 2001 as an upgrade to the manual zone control system implemented in 1998; London in 2003 and extended in 2007 (see London congestion charge ); Stockholm , tested in 2006 and made
12992-509: The world: Toronto in 1997 ( Highway 407 ), several roads in Norway (AutoPASS), Melbourne in 2000 ( CityLink ), and Tel Aviv also in 2000 ( Highway 6 ). Congestion pricing or urban toll schemes were implemented to enter the downtown area using ETC technology and/or cameras and video recognition technology to get the plate numbers in several cities around the world: urban tolling in Norway's three major cities: Singapore in 1974 introduced
13108-406: The year 2010, comparing overall fatality rates with motorway rates (regardless of traffic intensity): The German autobahn network illustrates the safety trade-offs of controlled access highways. The injury crash rate is very low on autobahns, while 22 people died per 1,000 injury crashes—although autobahns have a lower rate than the 29 deaths per 1,000 injury accidents on conventional rural roads,
13224-443: Was European route E4 from Gävle to Axmartavlan , Sweden. The high rate of crashes with severe personal injuries on that (and similar) roads did not cease until a median crash barrier was installed, transforming the fatal crashes into non-fatal crashes. Otherwise, freeways typically have at least two lanes in each direction; some busy ones can have as many as 16 or more lanes in total. In San Diego, California , Interstate 5 has
13340-562: Was extended through December 2011 and in January 2012 was replaced by a congestion pricing scheme called Area C . New York City considered the implementation of a congestion pricing scheme. New York City Council approved such a plan in 2008, but it was not implemented because the New York State Assembly did not approve it. (see New York congestion pricing ) In 2006, San Francisco transport authorities began
13456-403: Was the first country to deploy a full electronic toll collection system in motorways at national scale in 1989. In 1959, Nobel Economics Prize winner William Vickrey was the first to propose a similar system of electronic tolling for the Washington Metropolitan Area . He proposed that each car would be equipped with a transponder: "The transponder's personalized signal would be picked up when
