Study on an Effectiveness-Evaluation Method of Dynamic Channelization on Merging Sections of Tokyo Metropolitan Expressway

Abstract

    This paper suggests a performance-evaluation method for dynamic traffic operations, which uses two traffic simulators of different scales so that the influences of dynamic traffic operation strategy on not only the local area but also the road network are evaluated systemically. Dynamic channelization on JCT merging sections of Tokyo Metropolitan Expressway is analyzed as a case study. The result shows that, even if a strategy is effective for a local area, it is not always effective for the entire network. Thus, the method is considered to be effective for evaluating performance of dynamic traffic operations properly.
