Research on Sub-region Division of Regional Traffic by Fuzzy Theory

摘要

For the problem of sub-region division about regional traffic in urban traffic network. This paper uses fuzzy control theory to solve the problem, and defines adjacent intersections coordination coefficient to indicates the degree of association of adjacent intersections, the coefficient considers five factors, they are the intersection distance, signal cycle, traffic flow, traffic flow impact factor and the queue length. The paper elaborated the influence degree of each influence factor and calculating method. In the end selects the traffic network to simulation, and makes intersection average delay time as evaluation index, then uses the adaptive genetic algorithm sub-region agent to control the sub-region, to demonstrate the effectiveness of the division method.
