Exhaust gas from an internal combustion engine whose fuel includes nitromethane will contain nitric acid vapour, which is corrosive, and when inhaled causes a muscular reaction making it impossible to breathe. People who are likely to be exposed to it should wear
468-602: A flat fee either when they enter or when they exit the toll road. In a variant of the closed toll system, mainline barriers are present at the two endpoints of the toll road, and each interchange has a ramp toll that is paid upon exit or entry. In this case, a motorist pays a flat fee at the ramp toll and another flat fee at the end of the toll road; no ticket is necessary. In addition, with most systems, motorists may pay tolls only with cash or change; debit and credit cards are not accepted. However, some toll roads may have travel plazas with ATMs so motorists can stop and withdraw cash for
546-442: A specific infrastructure (e.g. roads, bridges). These concepts were widely used until the last century. However, the evolution in technology made it possible to implement road tolling policies based on different concepts. The different charging concepts are designed to suit different requirements regarding purpose of the charge, charging policy, the network to the charge, tariff class differentiation, et cetera: Some toll roads charge

Examples include the Sydney Harbour Bridge , Sydney Harbour Tunnel , and Eastern Distributor (these all charge tolls city-bound) in Australia, in the United States, crossings between Pennsylvania and New Jersey operated by Delaware River Port Authority and crossings between New Jersey and New York operated by Port Authority of New York and New Jersey . This technique
702-555: A toll payer's transponder or uses automatic number-plate recognition to charge drivers by debiting their accounts. Criticisms of toll roads include the time taken to stop and pay the toll, and the cost of the toll booth operators—up to about one-third of revenue in some cases. Automated toll-paying systems help minimise both of these. Others object to paying "twice" for the same road, namely in fuel taxes and in tolls. In addition to toll roads, toll bridges and toll tunnels are also used by public authorities to generate funds to repay

EGT is also a measure of engine health in gas-turbine engines (see below). During the first two minutes after starting the engine of a car that has not been operated for several hours, the amount of emissions can be very high. This occurs for two main reasons: Comparable with
1326-603: Is practical where the detour to avoid the toll is large or the toll differences are small. Traditionally, tolls were paid by hand at a toll gate. Although payments may still be made in cash, it is more common now to pay using an electronic toll collection system. In some places, payment is made using transponders which are affixed to the windscreen. Three systems of toll roads exist: open (with mainline barrier toll plazas ); closed (with entry/exit tolls); and open road (no toll booths, only electronic toll collection gantries at entrances and exits or at strategic locations on

Similar systems include SunPass in Florida , FasTrak in California , Good to Go in Washington state , and ExpressToll in Colorado . The systems use a small radio transponder mounted in or on a customer's vehicle to deduct toll fares from a pre-paid account as the vehicle passes through the toll barrier. This reduces manpower at toll booths and increases traffic flow and fuel efficiency by reducing

Most roads were not freely open to travel on in Europe during the Middle Ages, and the toll was one of many feudal fees paid for rights of usage in everyday life. Some major European "highways", such as the Via Regia and Via Imperii , offered protection to travelers in exchange for paying
3510-480: The gases resulting from combustion of the fuel and air mix are called exhaust gases. The composition varies from petrol to diesel engines, but is around these levels: The 10% oxygen for "diesel" is likely if the engine was idling, e.g. in a test rig. It is much less if the engine is running under load, although diesel engines always operate with an excess of air over fuel. The CO content for petrol engines varies from ≈15 ppm for well tuned engine with fuel injection and

It is also possible for motorists to enter an 'open toll road' after one toll barrier and exit before the next one, thus travelling on the toll road toll-free. Most open toll roads have ramp tolls or partial access junctions to prevent this practice, known in the U.S. as " shunpiking ". With a closed toll system, vehicles collect a ticket when entering
3978-523: The maintenance and improvement of most of the main roads in England and Wales, which were used to distribute agricultural and industrial goods economically. The tolls were a source of revenue for road building and maintenance, paid for by road users and not from general taxation. The turnpike trusts were gradually abolished from the 1870s. Most trusts improved existing roads, but some new roads, usually only short stretches, were also built. Thomas Telford 's Holyhead road followed Watling Street from London but

(This is different from "open road tolling", where no vehicles stop to pay a toll.) While this may save money from the lack of need to construct toll booths at every exit, it can cause traffic congestion while traffic queues at
4290-423: The motorways subject to toll payment must only proceed at a maximum speed of 30 kilometres per hour (20 mph) without the need to stop. The amount is directly proportional to the distance travelled by the vehicle, the coefficient of its class and a variable coefficient from motorway to motorway, called the kilometre rate. Unlike the closed motorway system, in the open system, the road user does not pay based on
4368-549: The need for better roads than the few and poorly-maintained tracks then available. Turnpike trusts were set up by individual Acts of Parliament , with powers to collect road tolls to repay loans for building, improving, and maintaining the principal roads in Britain . At their peak, in the 1830s, over 1,000 trusts administered around 30,000 miles (48,000 km) of turnpike road in England and Wales, taking tolls at almost 8,000 toll-gates. The trusts were ultimately responsible for

Many modern European roads were originally constructed as toll roads in order to recoup the costs of construction and maintenance, and to generate revenue from passing travelers. In 14th-century England, some of the most heavily used roads were repaired with money raised from tolls by pavage grants. Widespread toll roads sometimes restricted traffic so much, by their high tolls, that they interfered with trade and cheap transportation needed to alleviate local famines or shortages. Tolls were used in

Tolls are often collected at toll plazas, toll booths , toll houses , toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, many tolls are collected with electronic toll collection equipment which automatically communicates with
