| 摘要： | Ali-Scout is a dynamic route guidance system with an In-Vehicle Unit (IVU) that receives routing information from a Traffic Operations Center when passing infrared communication beacons installed at strategic intersections. As part of the FAST-TRAC evaluation, The University of Michigan simulated traffic in order to assess the impacts of Ali-Scout as the system scales up to higher levels of market penetration. Ultimately, the UM will apply traffic simulation to determine the combined impacts of Ali-Scout and SCATS (Sydney Coordinated and Adaptive Traffic System) on traffic in the Oakland County deployment area. In this paper, we present and discuss the results of the evaluation of Ali-Scout using traffic modeling and simulation under a variety of scenarios. Section 2 gives an overview of the Ali-Scout system and describes its main functional elements. Section 3 includes a description of the simulation scope and the main simulation modules developed to represent the Ali-Scout router and guidance components. In Section 4, we present and discuss the results of the Ali-Scout simulation runs. Section 5 concludes by summarizing the major results and providing insights as to the potential benefits of such a route guidance system. |
