| 摘要： | Ah-Scout is a dynamic route guidance system with an In-Vehicle Unit (IVU) that receives routing information from a Traffic Operations Center when passing infixed communication beacons installed at strategic intersections. As part of the FAST-TRAC evaluation, The University of Michigan Transportation Planning and Evaluation Group (UM TPEG) simulated traffic in order to assess the impacts of Ah-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 document, we present and discuss the results of the evaluation of Ah-Scout using traffic modeling and simulation under a variety of scenarios. Section 2 describes the functional elements of the Ah-Scout system. Section 3 gives an overview of the simulation model. Section 4 includes a description of the simulation scope and the main simulation modules developed to represent the Ali-Scout router and guidance components. Section 5 describes the background traffic model used in simulation. In Section 6, we present and discuss the results of the Ah-Scout simulation runs. Section 7 concludes the report by summarizing the major results and providing insights as to the potential benefits of such a route guidance system The simulation findings illustrate the effect of the level of market penetration on the individual and system performance. It appears that the benefits of Ah-Scout are signiticant only when the level of market penetration is below a certain level. Moreover, results show that the use of historical and real-time information as well as the density of beacon coverage play a major role in the effectiveness of this system. |
