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. [1] 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 ...
An example of headway on a railway system with multiple block section. Train B can only enter a section with a green or yellow "aspect" (light), and must reduce speed when passing a yellow signal to the point where they can stop within the sighting distance. Train movements in most rail systems are tightly controlled by railway signalling ...
Three parallel escalators; the direction of the middle escalator can be changed to double capacity in one direction (↑↑↓ or ↑↓↓).. Many public transport systems handle a high directional flow of passengers— often traveling to work in a city in the morning rush hour and away from the said city in the late afternoon.
The International Union of Railways produces documents on a variety of rail related topics, and published a leaflet on rail capacity. This leaflet provides a method of calculating route capacity based on the creation of paths through a rail route. The number of paths for a "standard" train is created, and then the train paths added.
In response to the 2008 Chatsworth train collision in California, a federal law required that positive train control (PTC) be implemented nationwide by 2015. [5] After several extensions, the Federal Railroad Administration (FRA) announced on December 29, 2020, that PTC was operating on all required freight and passenger rail routes. [ 6 ]
Headway – Distance between vehicles in a transit system measured in time or space; Passenger load factor – Capacity utilization of public transport; Passenger car (rail) Passenger pusher; Route capacity – Maximum occupancy of a route in a given time; Seating capacity – Number of people who can be seated in a specific space
[citation needed] Bus rapid transit is a bus-based mass transit system, where road infrastructure has been specifically constructed to allow better on time performance, and more frequent and high-speed services. This type of bus system is far less exposed to problem of low on time performance statistics than regular bus services.
