HEADWAY CONTROL THEORY OF VEHICULAR TRAFFIC

A multi-lane theory of vehicular traffic is described. The basic tenet of the theory is that the driver's behavior is based upon whether or not he is close enough to the car ahead to interact with it. A driver programs his behavior upon catching up to a slower moving car by either passing this car or following it. When the interaction begins, passing is first considered. If the conditions for passing are not satisfied, the driver will elect to follow. He does so by attempting to maintain a constant time headway between himself and the car ahead. Acceleration or deceleration is initiated as demanded by the instant value of the headway and the velocity differential between himself and the car ahead. A behavioral algorithm for the driver is written in a form suitable for computer analysis. The car-following algorithm and the passing algorithm are implemented and examined, and the feasibility of impressing an external control scheme upon the vehicular model is also examined. /Author/
