The Applications of microcomputers for vehicular traffic control

Abstract

Microcomputers have the capacity of providing complex and sophisticated control techniques. One system class requiring such complexity is that controlling vehicular traffic intersections. In this research, a microcomputer algorithm is proposed to control the traffic through an isolated intersection. The operation of the proposed algorithm was simulated by a general purpose computer, under different traffic trends. A simulated pre-timed control of the same intersection was taken as a comparative strategy to assess the one proposed. The geometry and data of a real intersection was chosen to be the test area. Measured intersection data was utilized to provide appropriate inputs to the computer during the different simulation days. A mathematical model is introduced to describe the intersection dynamics. The algorithm considerations were also implemented on a microcomputer and its operation was examined for simulated intersection input data
