What do headway, peak period, and off-peak period refer to?
Headway: The scheduled time interval between trains or buses operating on a particular transit route (e.g., the interval between the scheduled times a train or bus is planned to stop at a location to pick-up or deliver passengers.) Peak period: The period during which the maximum amount of travel (e.g. highest demand for passenger service) occurs. It may be specified as a morning (a.m.) or evening (p.m.) peak period. The peak period generally corresponds with the morning and evening commuter traveling periods as employees travel to and from their places of employment. Off-peak period: The time period outside of the morning (a.m.) and evening (p.m.) peak period. Passenger service demand at this time is less than experienced during the peak period(s).
