DEMAND-RESPONSIVE DECENTRALIZED URBAN TRAFFIC CONTROL. PART 2. NETWORK EXTENSIONS

Part 1 of this study described the development of models and a strategy for optimal real-time control of traffic at a sinalized intersection. The work has been extended in a number of ways which are described in this report. First, a NETSIM based simulation study was conducted to test the effectiveness of the strategy using field collected traffic flow data. Second, the basis demand-responsive optimization module was modified to consider impacts on adjacent nodes and thus allow its integration into a decentralized network control system. Various flow estimation procedures were developed and tested for this purpose. Finally, an open-loop feedback model is described which combines simulation andd optimization within an integrated network structure. The results reported in this study indicate the feasibility and advantages of applying demand-responsive strategies for traffic signal control at individual intersections as well as at flexibly coordinated network configurations.
