摘要

Left unmanaged, high vehicle volumes within urban traffic networks results in congested and slow moving traffic. This, in turn, leads to many negative economical and environmental consequences. It is important, then, to efficiently control the vehicles within these networks. Many researchers have made an effort to improve the efficiency of traffic signals using intelligent systems. However, many systems developed have been evaluated using unrealistic traffic models which often include single intersections and static traffic volumes. This thesis introduces a distributed/adaptive algorithm which can operate within a realistic environment. A realistic model of a section of downtown Ottawa is also developed and used to test the performance of the algorithm. Through simulation, acceptable algorithm parameters are identified and the algorithm's performance is compared to that of a fixed controller. It is found that an adaptive approach to signal control results in higher vehicle speeds than those found using a fixed controller.
