CONTROL OF BUS HEADWAYS BY TRAFFIC SIGNAL TIMING METHODS

Bus bunching causes uneven passenger loadings and increases the average passenger waiting time. Bunching is caused by an unstable relationship between delay in the actual bus arrival time and passenger loading time requirements. An appropriate mathematical representation of this process is provided, and the general mathematical requirements for stabilizing the process are described. It is shown that if the time of arrival of the buses at specified points on a route such as signalized arterial can be obtained, it is possible to develop traffic signal algorithms which can essentially eliminate this instability and generally control the headway variations to acceptable levels. An example demonstrating the performance of the algorithm on a particular bus route is provided.
