Road transport Road transport The AASHO Road Test was a series of experiments carried out by the American Association of State Highway and Transportation Officials to determine how traffic contributed to the deterioration of road surfaces. This study, carried out in the late 1950s in Ottawa, Illinois, is frequently quoted as a primary source of experimental data when vehicle damage to highways is considered, for the purposes of road design, vehicle taxation and costing. ...more on Wikipedia about "AASHO Road Test"
An alley or alleyway is a type of road found in densely populated urban areas. Alleys usually run between or behind buildings to allow for delivery and collection. Originally they were required for waste collection, delivery of coal (before the widespread adoption of central heating), or rear access for fire engines and parking. Blind alleys have no outlet at one end. ...more on Wikipedia about "Alley"
An alternate route is a bannered highway that provides an alternate alignment for a highway. Originally, the term for these routes was "optional"; but in 1959, the designation became alternate. In some cases, a business route exists and a third such alignment is needed (this was the case with former Alternate US 71 which bypassed Joplin, Missouri). Alternatively, a town (or towns) desired to be on the particular highway, which was routed differently to put an important town or city on the route. The American Association of State Highway and Transportation Officials has called for the removal of alternate routes, though some still exist. In Oklahoma, U.S. Highway 412 has an alternate route where the main highway is routed down the Cherokee Turnpike; this route has been designated Scenic US 412, though it is shown as "Alternate US 412" on some maps. ...more on Wikipedia about "Alternate route (highway)"
Ancient trackway can refer to any track or trail whose origin is lost in antiquity. Such paths existed from the earliest times and in every part of the globe. The term is commonly used in the British isles to describe the ancient trackways that already existed when the Romans arrived, in Britain. Such trackways, were often built on by the Romans and form the foundations of some of the current system of roads. ...more on Wikipedia about "Ancient trackway"
An arterial road is a moderate or high-capacity road which is just below a highway level of service. Much like a biological artery, an arterial road carries large volumes of traffic between areas in urban centres. They are noted for their lack of residential entrances directly onto the road (except in older or more dense communities); they are designed to carry traffic between neighbourhoods, and have intersections with collector and local streets. Often, commercial areas such as shopping centres, gas stations and other businesses are located on them. Arterial roads also link up to expressways and freeways with interchanges. ...more on Wikipedia about "Arterial road"
An automated highway system (AHS) or Smart Roads, is an advanced Intelligent transportation system technology designed to provide for driverless cars on specific rights-of-way. It is most often touted as a means of traffic congestion relief, since it drastically reduces following distances and thus allow more cars to occupy a given stretch of road. ...more on Wikipedia about "Automated highway system"
A bannered highway is an alternate route or spur designated with a banner plate above (or occasionally below) the route shield, or a suffix after the number in the shield of U.S. Highways and state highways. Originally, the terms used were "City", "Truck", and "Optional". In 1959-1960, the terms were changed to " Business", " Bypass", and " Alternate", respectively. The American Association of State Highway and Transportation Officials (AASHTO) has called for the removal of "alternate" routes, though some still exist. In addition, "spur" routes exist (roads which leave the main route, but do not reconnect with it), and two "scenic" routes also exist (for US 40 and US 412). In the past, "temporary" routes also existed. In the case of state routes, this is generally restricted to primary state routes, not secondary state routes, though Missouri has three supplemental routes which have short spur routes. ...more on Wikipedia about "Bannered highway" Please inform your friends about http://www.shortopedia.com shortopedia
The Barnes Dance is a pedestrian crossing system that stops all traffic and allows pedestrians to cross intersections in every direction at the same time. The Barnes Dance was first used in Kansas City and Vancouver in the late 1940s. Subsequently it was adopted in other cities such as Denver, Baltimore, New York, Montreal, Beverly Hills, and the famous Shibuya crossing in Tokyo. ...more on Wikipedia about "Barnes Dance"

A bull bar (also roo bar in Australia) is a device fitted to the front of a vehicle to protect the vehicle (and its passengers) from damage in a collision with an animal. They vary considerably in size and form but are usually made out of welded steel or aluminium tubing and more recently polycarbonate materials. ...more on Wikipedia about "Bull bar"
A business route is a road in the United States that is a branch from an Interstate, U.S. or state highway route. The purpose of business routes is to link the mainline of its parent route to the business district of a city or town. Usually, the business route connects to its parent route on both ends. Until 1960, these roads were called "city routes". ...more on Wikipedia about "Business route"
Bypass routes are a type of bannered highway usually used when the main route of the highway goes through a town and an alternate route of the same highway goes around the highway. The routes were originally designated "truck routes", but the designation was changed to "bypass" in 1959-1960. In a few cases, both a bypass and a business route exist, sometimes without a non-bannered highway (this is the case in Lexington, Kentucky with U.S. Highway 60). Bypass routes are less common than business routes. ...more on Wikipedia about "Bypass route"

A Car Free Day is an event organized in different places in different ways, but with the common goal of taking a fair number of cars off the streets of a city or some target area or neighborhood for all or part of a day, in order to give the people who live and work there a chance to consider how their city might look and work with a lot fewer cars. While projects along these lines had taken place from time to time on an ad hoc basis starting with the 1973/74 “oil crisis”, it was only in October 1994 that a structured call for such projects was issued in a keynote speech by Eric Britton at the International Ciudades Accesibles (Accessible Cities) Conference held in Toledo (Spain). http://www.ecoplan.org/carfreeday/general/thursday.htm Thursday: A Breakthrough Strategy for Reducing Car Dependence in Cities) ...more on Wikipedia about "Car Free Days"
Car safety is the avoidance of car accidents or the minimization of harmful effects of accidents, in particular as pertaining to human life and health.

Car-trains are a possible key advance in transportation technology. They have the potential to alleviate congestion by increasing throughput (number of vehicles per lane per hour) by a factor of at least two. Vehicles that are physically coupled or able to follow with a gap of less than 1 foot can reduce aerodynamic drag more than 50% (see graph and image). However, significant development issues regarding the controllability, safety and new driver behavior remain to be resolved. ...more on Wikipedia about "Car-trains"
Carsharing is a system where a fleet of cars (or other vehicles) is owned and operated/overseen by a company, public agency, cooperative, ad hoc grouping, or even a single individual, and made available for use by members of the carshare group in a wide variety of ways. The costs and troubles of vehicle purchase, ownership and maintenance are transferred to a central organizer (the Carshare Operator or more familiarly CSO). It has been around in various forms for more than half a century, but it is only in the last decade that it has begun to gather force as a viable alternative to car ownership—for some people and some places. Today there are more than six hundred cities in the world ** where you can carshare this morning. ...more on Wikipedia about "Carsharing"
A cat's eye is a safety device used in road construction in the United Kingdom. It usually has some form of a retroreflective mechanism such as paint or a plastic corner reflector (Originally, these were glass spheres about 1 cm in diameter in a brass holder) built into a sturdy housing, capable of surviving as vehicles pass over it. In places where roads are subject to snow, they must also survive being driven over by a snow plough. They are placed along road markings, as they serve to highlight these markings at night, fog, or low lighting conditions. ...more on Wikipedia about "Cat's eye (road)"
