Operational Optimization and Simulation of Urban Arterial Road Based on Network Microcirculation

Traffic congestion has been the main problem appearing in China, only relying on a single traffic control or management has been unable to resolve the impact of increasing traffic flow, and it should be avoided from aspect of network microcirculation. Firstly, definition of traffic network microcirculation, the problem and basic strategies were introduced in the paper, operational optimization method of network microcirculation is put forward; with network microcirculation, we then make a thorough analysis of traffic organization of road sections, and case study was used to interpret operation mechanism of microcirculation network, in order to alleviate traffic jam by separating some vehicle, balance traffic network demand. At last one example was introduced to prove performance of the methods. The results indicate that traffic improvement should be accomplished by the operational system optimization theory of network microcirculation.
