摘要
针对城市高架道路匝道的功能,分析了其车流在地面路网的分布特征,提出了衔接评估理论的体系及指标,并给出了评估理论在匝道定位优化比选阶段应用的流程。
Based on the study of the function of elevated-road ramp,the distribution characterization of traffic-flow on the road network is analyzed.The theory and index to evaluate the connection between ramp and its road network are founded.Graphology for application based on the evaluation theory,to optimize and compare the ramp location,is also given.
