TIME HEADWAYS ON CROSSING THE STOP-LINE AFTER QUEUEING AT TRAFFIC LIGHTS

Observations undertaken to determine the time headways between vehicles moving straight ahead which have stopped at traffic lights are presented, which indicate that the headways tend to converge to a value around two seconds. It is suggested that the wide differences between the values of the time taken for the first vehicle to cross the stop-line are accounted for by the lack of agreement on a standard position for this line. It is considered that a model is required to explain such observations. The author examines what determines the headway, the importance of reaction time, rate of acceleration, or whether the decision to move forward rests with the driver. A model to answer these questions has been derived following the development of road traffic simulation programs called bustle; information on this model is presented. /TRRL/
