  2. Headway - Wikipedia

    en.wikipedia.org/wiki/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 ...

    en.wikipedia.org/wiki/Three-phase_traffic_theory

    The microscopic criteria are as follows (see Sec. 2.6 in the book [5]): If in single-vehicle (microscopic) data related to congested traffic the "flow-interruption interval", i.e., a time headway between two vehicles following each other is observed, which is much longer than the mean time delay in vehicle acceleration from a wide moving jam ...

  4. Traffic flow - Wikipedia

    en.wikipedia.org/wiki/Traffic_flow

    The vertical separation (distance) between parallel trajectories is the vehicle spacing (s) between a leading and following vehicle. Similarly, the horizontal separation (time) represents the vehicle headway (h). A time-space diagram is useful for relating headway and spacing to traffic flow and density, respectively.

    Headway – Distance between vehicles in a transit system measured in time or space; Passenger load factor – Capacity utilization of public transport; Traffic flow – Study of interactions between travellers and infrastructure Traffic congestion – Transport condition characterized by slower speed and high density

  6. Dwell time (transportation) - Wikipedia

    en.wikipedia.org/wiki/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. [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 ...

  9. Fundamental diagram of traffic flow - Wikipedia

    en.wikipedia.org/wiki/Fundamental_diagram_of...

    The flow and capacity at which this point occurs is the optimum flow and optimum density, respectively. The flow density diagram is used to give the traffic condition of a roadway. With the traffic conditions, time-space diagrams can be created to give travel time, delay, and queue lengths of a road segment.
