TRAFFIC SIGNAL-DESIGN FOR PEDESTRIANS ON DIVIDED HIGHWAYS

Consideration for the safety and convenience of pedestrians is generally accepted as part of the requirements for traffic signal design at intersections. Vehicular traffic delay, number of stops, queue length, operating costs, and safety are criteria considered in traffic signal optimization. For pedestrians, however, no equivalent criteria have as yet been established, although the need for an optimal balance between the right-of-way to pedestrians and vehicles is generally recognized. A method for reducing pedestrian delay time at traffic signals on divided highways will be presented in this article. The article shows that, according to this method, vehicle efficiency criteria will be either unaffected or improved.
