The number of vehicles queuing behind the stop line is recorded manually and the times when the fourth to the last queued vehicle cross the stop line are extracted to calculate the saturation headways. Although the field measurement method can estimate the saturation headway and hence the SFR, it has the following two limitations:
Provided that the headway of major stream follows M3 distribution, headway samples are extracted from major-stream headways when minor-stream vehicles arrive before an intersection.
Gap acceptance theory has two basic elements: the distribution of headways between priority vehicles and the usefulness of those headways to the entering vehicles.
Headways Arts creative director, Alison Walton-Robson, said: "A great piece of live theatre can illustrate a person's life experience in a way that nothing else can.
Even an alert driver may fail to maintain a safe headway from the car ahead because of a perceptual inadequacy in estimating headways (Taieb & Shinar, 2001).
It is always desirable for buses to run on a route with equal headways. Nevertheless, this is often difficult to accomplish due to complex conditions related to traffic on the road and demands from passengers at bus stops.
Consequently, past research carried out by Taieb and Shinar (2001) showed that drivers tend to overestimate their headways despite years of driving experience.
A field study was conducted to evaluate drivers' actual headways in car-following situations, their relationship to the drivers' brake reaction times, and their relationship to the drivers' ability to estimate those headways using different metrics.
