Routing is the process of selecting a path for traffic in a network, or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet.
Traffic on roads consists of road users including pedestrians, ridden or herded animals, vehicles, streetcars, buses and other conveyances, either singly or together, while using the public way for purposes of travel. Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic.
Commercial Vehicle Operations is an application of Intelligent Transportation Systems for trucks.
Gridlock is a form of traffic congestion where "continuous queues of vehicles block an entire network of intersecting streets, bringing traffic in all directions to a complete standstill". The term originates from a situation possible in a grid plan where intersections are blocked, preventing vehicles from either moving forwards through the intersection or backing up to an upstream intersection.
Carpooling is the sharing of car journeys so that more than one person travels in a car, and prevents the need for others to have to drive to a location themselves.
In public transport, bus bunching, clumping, convoying, piggybacking or platooning refers to a group of two or more transit vehicles, running along the same route, which were scheduled to be evenly spaced, but instead run in the same place at the same time. This occurs when at least one of the vehicles is unable to keep to its schedule and therefore ends up in the same location as one or more other vehicles which are supposed to be behind it.
A weigh station is a checkpoint along a highway to inspect vehicular weights. Usually, trucks and commercial vehicles are subject to the inspection.
In public transport, a request stop, flag stop, or whistle stop is a stop or station or airport at which trains, buses or airline flights respectively stop only on request; that is, only if there are passengers or freight to be picked up or dropped off. In this way, stops with low passenger counts can be incorporated into a route without introducing unnecessary delay. Vehicles may also save fuel by continuing through a station when there is no need to stop.
A trip computer is a computer fitted to some cars; most modern trip computers record, calculate, and display the distance travelled, the average speed, the average fuel consumption, and real-time fuel consumption.
Everybody's Trucking is the first episode of the seventh series of the British television sitcom Dad's Army. It was originally transmitted on 15 November 1974.
Headway is a measurement of the distance or time between vehicles in a transit system. The minimum headway is the shortest such distance or time achievable by a system without a reduction in the speed of vehicles. The precise definition varies depending on the application, but it is most commonly measured as the distance from the tip of one vehicle to the tip of the next one behind it. It can be expressed as the distance between vehicles, or as time it will take for the trailing vehicle to cover that distance. A "shorter" headway signifies closer spacing between the vehicles. Freight trains might have headways measured in parts of an hour, metro systems operate with headways on the order of 1 to 5 minutes, and vehicles on a freeway can have as little as 2 seconds headway between them.
The vehicle routing problem (VRP) is a combinatorial optimization and integer programming problem which asks "What is the optimal set of routes for a fleet of vehicles to traverse in order to deliver to a given set of customers?". It generalises the well-known travelling salesman problem (TSP). It first appeared in a paper by George Dantzig and John Ramser in 1959, in which first algorithmic approach was written and was applied to petrol deliveries. Often, the context is that of delivering goods located at a central depot to customers who have placed orders for such goods. The objective of the VRP is to minimize the total route cost. In 1964, Clarke and Wright improved on Dantzig and Ramser's approach using an effective greedy approach called the savings algorithm.
The Ride is the Massachusetts Bay Transportation Authority's paratransit program for people with physical, mental or cognitive disabilities that make it difficult or impossible to ride the MBTA's fixed-route bus, train, and ferry services. The program uses wheelchair accessible vans for door-to-door service; drivers are required to assist passengers to and from the vehicle. The Ride satisfies requirements under the 1990 Americans With Disabilities Act for transit systems to provide services for those who cannot ride the fixed-route system. The service began in April 1977 with two vehicles.
In public transportation, schedule adherence or on-time performance refers to the level of success of the service remaining on the published schedule. On time performance, sometimes referred to as on time running, is normally expressed as a percentage, with a higher percentage meaning more vehicles are on time. The level of on time performance for many transport systems is a very important measure of the effectiveness of the system.
Blacksburg Transit, or simply BT, is a local government-owned urban-suburban bus line based in Blacksburg, Virginia. The system originated in 1983 with six buses, but has since expanded its operation to 48 buses and 11 vans. Ridership exceeds 3.5 million passenger trips per year. Its ridership is dominated by Virginia Tech students who account for 90 percent of all riders, with the remaining 10 percent being split between Tech faculty and staff, and other Blacksburg citizens. Blacksburg Transit serves the towns of Blacksburg, Christiansburg and limited unincorporated portions of Montgomery County.
Crew scheduling is the process of assigning crews to operate transportation systems, such as rail lines or airlines.
A vehicle tracking system combines the use of automatic vehicle location in individual vehicles with software that collects these fleet data for a comprehensive picture of vehicle locations. Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software. Urban public transit authorities are an increasingly common user of vehicle tracking systems, particularly in large cities.
An intercity bus driver is a bus driver whose duties involve driving a bus between cities. It is one of four common positions available to those capable of driving buses. Intercity bus drivers may be employed for public or private companies. It varies by country which is more common. But many countries have regulations on the training and certification requirements and the hours of intercity drivers.
Valley Metro Bus is a transit bus system for public transport in Maricopa County, Arizona, United States. Buses are operated by private companies contracted by Valley Metro and the City of Phoenix. Service currently operates throughout the broader Phoenix Metropolitan Area. All buses have wheelchair ramps or lifts, and with the exception of paratransit vehicles all buses have bike racks.
