  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 ...

  3. Passenger car equivalent - Wikipedia

    en.wikipedia.org/wiki/Passenger_car_equivalent

    Passenger car equivalent (PCE) or passenger car unit (PCU) is a metric used in transportation engineering to assess traffic-flow rate on a highway. [1]A passenger car equivalent is essentially the impact that a mode of transport has on traffic variables (such as headway, speed, density) compared to a single car.

  4. Traffic flow - Wikipedia

    en.wikipedia.org/wiki/Traffic_flow

    In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.

  5. Passengers per hour per direction - Wikipedia

    en.wikipedia.org/wiki/Passengers_per_hour_per...

    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.

  6. Dwell time (transportation) - Wikipedia

    en.wikipedia.org/wiki/Dwell_time_(transportation)

    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.

    How to calculate the current ratio. You can calculate the current ratio by dividing a company’s total current assets by its total current liabilities. Again, current assets are resources that ...

  8. On-time performance - Wikipedia

    en.wikipedia.org/wiki/On-time_performance

    To calculate the percentage of vehicles on time, comparison is needed with the timetable. A comparison is often completed for arrival time rather than departure time, but both are common. Departure times are normally more on-time than arrival times, as incidents and breakdowns occur that reduce the on time performance.

  9. Saturation (traffic) - Wikipedia

    en.wikipedia.org/wiki/Saturation_(traffic)

    A DoS value of 100% meaning that demand and capacity are equal and no further traffic is able to progress through the junction. The formula to calculate DoS is: Degree of saturation = (demand x cycle time) / (saturation flow x effective green time) Values over 85%-90% typically indicate traffic congestion, with queues of vehicles beginning to form.
