A model of a mid-block pedestrian signal within a fixed time traffic signal system

A mid-block pedestrian traffic signal is an important traffic control device to allow pedestrians to safely cross a busy roadway. There are few methods by which the impact, on vehicles and pedestrians, of such a traffic control device can be determined. No traffic operations model allows for the direct simulation of such a traffic signal. This paper presents the theoretical background, the PEDXING computer program and the program results used to develop a model of a mid-block pedestrian traffic signal within a fixed-time traffic signal system. The output of the model is the average delay for vehicles and the average delay for pedestrians as a principal measure of effectiveness of the system operation.
