Transportation engineering

The time gap between successive vehicles on a line

In transit and traffic engineering, headway is the time interval (or, as spacing, the distance) between successive vehicles passing a point on the same route, the gap between one bus or train and the next. Short, even headways define frequent service, while the system is unstable to bunching, in which a delayed vehicle falls further behind and the one following catches up. Nagatani's 2001 model analyses the bunching transition in a time-headway model of a bus route, and Vuchic's Urban transit systems and technology treats headway as a core service parameter. The referent is the temporal spacing between vehicles, measured in minutes or seconds and in its regularity.[1][2]
