A Danish road directorate states that in town centers it is important to be able to cycle in both directions in all streets, and that in certain circumstances, two-way cycle traffic can be accommodated in an otherwise one-way street. One-way street systems can be viewed as either

Apart from signposting in and between urban areas, mountain pass cycling milestones have become an important service for bicycle tourists. They provide cyclists with information about their current position with regard to the summit of the mountain pass . Numbered-node cycle networks are increasingly used in Europe to give flexible, low-cost signage. One method for reducing potential friction between cyclists and motorized vehicles
392-475: A sharrow is a street marking that indicates the preferred lateral position for cyclists (to avoid the door zone and other obstacles) where dedicated bike lanes are not available. A 2-1 road is a roadway striping configuration which provides for two-way motor vehicle and bicycle traffic using a central vehicular travel lane and "advisory" bike lanes on either side. The center lane is dedicated to, and shared by, motorists traveling in both directions. The center lane

833-461: Is noted that further research is recommended to confirm findings. Bikeways can fall into these main categories: separated in-roadway bikeways such as bike lanes and buffered bike lanes; physically separated in-roadway bikeways such as cycle tracks; right-of-way paths such as bike paths and shared use paths; and shared in-roadway bikeways such as bike boulevards, shared lane markings, and advisory bike lanes. The exact categorization changes depending on
882-526: Is to provide "wide kerb", or "nearside", lanes (UK terminology) or " wide outside through lane " (U.S. terminology). These extra-wide lanes increase the probability that motorists pass cyclists at a safe distance without having to change lanes. This is held to be particularly important on routes with a high proportion of wide vehicles such as buses or heavy goods vehicles (HGVs). They also provide more room for cyclists to filter past queues of cars in congested conditions and to safely overtake each other. Due to

Starting in the 1970s, the city of Copenhagen , where now 36% of the trips are done by bicycle, adopted a policy of reducing available car parking capacity by several per cents per year. The city of Amsterdam , where around 40% of all trips are by bicycle, adopted similar parking reduction policies in the 80s and 90s. Direct traffic reduction methods can involve straightforward bans or more subtle methods like road pricing schemes or road diets . The London congestion charge reportedly resulted in
980-638: The European Commission policy document on cycle promotion. Shared space schemes extend this principle further by removing the reliance on lane markings altogether, and also removing road signs and signals, allowing all road users to use any part of the road, and giving all road users equal priority and equal responsibility for each other's safety. Experiences where these schemes are in use show that road users, particularly motorists, undirected by signs, kerbs, or road markings, reduce their speed and establish eye contact with other users. Results from

1225-570: The Netherlands, however, cyclists are frequently granted exemptions from one-way street restrictions, which improves cycling traffic flow while restricting motorized vehicles. German research indicates that making one-way streets two-way for cyclists results in a reduction in the total number of collisions. There are often restrictions to what one-way streets are good candidates for allowing two-way cycling traffic. In Belgium road authorities in principle allow any one-way street in 50 kilometres per hour (31 mph) zones to be two-way for cyclists if

Although AASHTO sets transportation standards and policy for the United States as a whole, AASHTO is not an agency of the federal government; rather it is an organization of the states themselves. Policies of AASHTO are not federal laws or policies, but rather are ways to coordinate state laws and policies in
1323-1095: The available lane is at least 3 metres (9.8 ft) wide (area free from parking) and no specific local circumstances prevent it. Denmark , a country with high cycling levels, does not use one-way systems to improve traffic flow. Some commentators argue that the initial goal should be to dismantle large one-way street systems as a traffic calming/traffic reduction measure, followed by the provision of two-way cyclist access on any one-way streets that remain. In general, junction designs that favor higher-speed turning, weaving and merging movements by motorists tend to be hostile for cyclists. Free-flowing arrangements can be hazardous for cyclists and should be avoided. Features such as large entry curvature, slip-roads and high flow roundabouts are associated with increased risk of car–cyclist collisions. Cycling advocates argue for modifications and alternative junction types that resolve these issues such as reducing kerb radii on street corners, eliminating slip roads and replacing large roundabouts with signalized intersections. Another approach which

There is no single usage of segregation ; in some cases it can mean the exclusion of motor vehicles and in other cases the exclusion of pedestrians as well. Thus, it includes bike lanes with solid painted lines but not lanes with dotted lines and advisory bike lanes where motor vehicles are allowed to encroach on the lane. It includes cycle tracks as physically distinct from
1470-501: The city center. Similarly, Groningen is divided into four zones that cannot be crossed by private motor-traffic, (private cars must use the ring road instead). Cyclists and other traffic can pass between the zones and cycling accounts for 50%+ of trips in Groningen (which reputedly has the third-highest proportion of cycle traffic of any city). The Swedish city of Gothenburg uses a similar system of traffic cells. Another approach

In the US, slow-street movements have been introduced by erecting makeshift barriers to slow traffic and allow bikers and walkers to safely share the road with motorists . Removing traffic can be achieved by straightforward diversion or alternatively reduction. Diversion involves routing through-traffic away from roads used by high numbers of cyclists and pedestrians. Examples of diversion include

The cost of building a bicycle super highway depends on many things, but is usually between €300,000/km (for a wide dedicated cycle track) and €800,000/km (when complex civil engineering structures are needed). There are various measures cities and regions often take on the roadway to make it more cycling friendly and safer. Aspects of infrastructure may be viewed as either cyclist-hostile or as cyclist-friendly . However, scientific research indicates that different groups of cyclists show varying preferences of which aspects of cycling infrastructure are most relevant when choosing
1764-532: The implementation of such a scheme. Even without shared street implementation, creating 30 km/h zones (or 20 mph zone ) has been shown to reduce crash rates and increase numbers of cyclists and pedestrians. Other studies have revealed that lower speeds reduce community severance caused by high speed roads. Research has shown that there is more neighborhood interaction and community cohesion when speeds are reduced to 20 mph. German research indicates that making one-way streets two-way for cyclists results in

1911-826: The position of having to "run" red lights if no motorized vehicle arrives to trigger a signal change. Some cities use urban adaptive traffic control systems (UTCs), which use linked traffic signals to manage traffic in response to changes in demand. There is an argument that using a UTC system merely to provide for increased capacity for motor traffic will simply drive growth in such traffic. However, there are more direct negative impacts. For instance, where signals are arranged to provide motor traffic with so-called green waves , this can create "red waves" for other road users such as cyclists and public transport services. Traffic managers in Copenhagen have now turned this approach on its head and are linking cyclist-specific traffic signals on
1960-1107: The red signal phase. On large roundabouts of the design typically used in the UK and Ireland, cyclists have an injury accident rate that is 14–16 times that of motorists. Research indicates that excessive sightlines at uncontrolled intersections compound these effects. In the UK, a survey of over 8,000 highly experienced and mainly adult male Cyclists Touring Club members found that 28% avoided roundabouts on their regular journey if at all possible. The Dutch CROW guidelines recommend roundabouts only for intersections with motorized traffic up to 1500 per hour. To accommodate greater volumes of traffic, they recommend traffic light intersections or grade separation for cyclists. Examples of grade separation for cyclists include tunnels, or more spectacularly, raised "floating" roundabouts for cyclists. How traffic signals are designed and implemented directly impacts cyclists. For instance, poorly adjusted vehicle detector systems, used to trigger signal changes, may not correctly detect cyclists. This can leave cyclists in

Paths which are shared with pedestrians and other non-motorized traffic are not considered segregated and are typically called shared use path , multi-use path in North America and shared-use footway in the UK.

The term bikeway is largely used in North America to describe all routes that have been designed or updated to encourage more cycling or make cycling safer. In some jurisdictions such as the United Kingdom, segregated cycling facility is sometimes preferred to describe cycling infrastructure which has varying degrees of separation from motorized traffic, or which has excluded pedestrian traffic in
