Dwell Time (transportation)
In transportation, dwell time or terminal dwell time refers to the time a vehicle such as a public transit bus or train spends at a scheduled stop without moving. Typically, this time is spent boarding or deboarding passengers and baggage, but it may also be spent waiting for traffic ahead to clear, trying to merge into parallel traffic, or idling time in order to get back on schedule. Dwell time is one common measure of efficiency in public transport, with shorter dwell times being universally desirable. Rail systems Dwell times are particularly important for a rail system. Rail headways increase where the dwell times are high. Dwell times are an important focus for rail systems; a reduction in a dwell time can often result in a reduced headway. Passengers who want to board and alight from a train need time to do so. Almost always passengers disembark first, and then passengers waiting on a platform board. A variety of different factors determine how long this takes, including t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Bus
A transit bus (also big bus, commuter bus, city bus, town bus, urban bus, stage bus, public bus, public transit bus, or simply bus) is a type of bus used in public transport bus services. Several configurations are used, including low-floor buses, High-floor, high-floor buses, double-decker buses, articulated buses and midibuses. These are distinct from all-seated Coach (bus), coaches used for intercity travel and smaller minibuses, for more flexible services. Specifications The US Federal Transit Administration offers some definitions of terms for a bus in public transit service. "Bus means a rubber-tired automotive vehicle used for the provision of public transportation service by or for a recipient of FTA financial assistance." FTA also adds that automotive means that the bus does not rely on external power sources for its motion; its motor and fuel or battery are contained in the bus. It defines public transportation service as "the operation of a vehicle that provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomo ...

Headway
Headway is the distance or duration 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 (front end) 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. Airplanes operate with headways measured in hours or days, freight trains and commuter rail systems might have headways measured in parts of an hour, metro and light rail systems operate with headways on the order of 90 seconds to 20 minutes, and vehicles on a freeway can have as little as 2 seconds headway between them. Headway is a key input in calculating the overall route capacity of any transit syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Transit
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separation, grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electric railway, electric railways, that unlike buses or trams operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles. Modern services on rapid transit systems are provided on designated lines between metro station, stations typically using electric multiple units on railway tracks. Some systems use rubber-tyred metro, guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typica ...

World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft. World War I was one of the List of wars by death toll, deadliest conflicts in history, resulting in an estimated World War I casualties, 10 million military dead and more than 20 million wounded, plus some 10 million civilian de ...

Spanish Solution
In railway and rapid transit parlance, the Spanish solution is a station layout with two railway platforms, one on each side of the track, which allows for separate platforms for boarding and alighting. The "Spanish solution" is used in several stations of the Madrid Metro (e.g. Avenida de América (Madrid Metro), Avenida de América) and Barcelona Metro (e.g. Sant Andreu (Barcelona Metro), Sant Andreu). Description This platform arrangement allows the separation of passenger streams by using one platform only for boarding, and the other one only for alighting. The separate designation of platforms for boarding and alighting has been proven effective at reducing Dwell time (transportation), dwell time at stations with high passenger numbers. The Spanish solution is most commonly applied at high-frequency underground Rapid transit, metro stations. Stations are sometimes retrofitted to include a Spanish solution layout to expand the capacity of existing stations when there is no ...

Airport Rail Link
An airport rail link is a service providing passenger rail transport between an airport and a nearby city. Direct links operate straight from the airport terminal to the city, while other links require an intermediate use of a people mover or airport bus, shuttle bus. Advantages for the passenger include faster travel times and easy connections with other public transport. Advantages for the airport include increased patronage and enhanced accessibility for staff. Additionally, authorities have benefitted from less highway congestion, less pollution, and more business opportunities. History Although airport rail links have been a popular solution in Europe and Japan for decades, only recently have links been constructed in North America, South America, Africa, Oceania, and the rest of Asia. Some early examples of inter-city railway stations built to serve an airport include: The first rapid transit station to connect with an airport was Berlin's Berlin U-Bahn, U-Bahn U6 (Be ...

Wheelchair Lift
A wheelchair lift, also known as a platform lift, or vertical platform lift, is a fully powered device designed to raise a wheelchair and its occupant in order to overcome a step or similar vertical barrier. Wheelchair lifts can be installed in homes or businesses and are often added to both private and public vehicles in order to meet accessibility requirements laid out by disability acts. These mobility devices are often installed in homes as an alternative to a stair lift, which only transport a passenger and not his/her wheelchair or mobility scooter. Regulations In the United States, the Americans with Disabilities Act of 1990 (ADA) required that all new mass transit vehicles placed into service after July 1, 1993, be accessible to persons in wheelchairs,"Getting on board" (July–August 1993). ''Trolleybus Magazine'' No. 190, pp. 86–87. National Trolleybus Association (UK). . and until the 2000s, this requirement was most commonly met by the inclusion of a wheelc ...

Transportation Planning
Transportation planning is the process of defining future policies, goals, investments, and spatial planning designs to prepare for future needs to move people and goods to destinations. As practiced today, it is a collaborative process that incorporates the input of many stakeholders including various government agencies, the public and private businesses. Transportation planners apply a multi-modal and/or comprehensive approach to analyzing the wide range of alternatives and impacts on the transportation system to influence beneficial outcomes. Transportation planning is also commonly referred to as transport planning internationally, and is involved with the evaluation, assessment, design, and siting of transport facilities (generally streets, highways, bike lanes, and public transport lines). Models and sustainability Transportation planning, or transport planning, has historically followed the rational planning model of defining goals and objectives, identifying ...

Public Transport
Public transport (also known as public transit, mass transit, or simply transit) are forms of transport available to the general public. It typically uses a fixed schedule, route and charges a fixed fare. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include Public transport bus service, city buses, trolleybuses, trams (or light rail) and Passenger rail transport, passenger trains, rapid transit (metro/subway/underground, etc.) and ferry, ferries. Public transport between cities is dominated by airlines, intercity bus service, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world. Most public transport systems run along fixed routes with set embarkation/disembarkation points to a prearranged timetable, with the most frequent services running to a headwa ...
