Abstract

Automatic control of traffic signals in many cities are often based on a constant green-to-red cycle. The time period for green light (or red light) to be on is fixed, and is determined based on a stochastic model. In some situations, a human operator, or a fixed timer, may change the time period dyring time intervals where there is heavy traffic--typically during commuting times. Although in today's traffic controllers, the time period for green light can be changed in certain circumstances, in general they are not able to adjust dynamically to traffic changes. This paper presents the design of a controller that considers the intersection of two two-way streets and is able to adjust to environmental changes. Simulation of the proposed controller has produced results more in line with what we expected. In many cases, the proposed system has produced better results than systems that are based on a constant green-to-red cycle.
