太原绕城高速公路功能调整枢纽通行能力研究

Study on Traffic Capacity of Functional Adjustment Hub of Taiyuan Ring Expressway

通过对太原市周边路网的调查,收集了周边高速公路交通量通行数据,预测太原市周边高速枢纽未来交通量。同时通过收集各高速枢纽型式并判断其各匝道通行能力,将匝道的服务水平作为评价指标,通过增设匝道来改善部分枢纽通行效率,在满足出行费用最优的前提下,获得较为理想的路网服务水平,可对类似项目提供一定参考。

Through the investigation of the road network around Taiyuan, the traffic volume data of surrounding expressways was collected to forecast the future traffic volume. The formation of each expressway hub was generalized and the traffic capacity of each ramp was estimated. By using the service level of the ramp as the evaluation index and adding ramps to improve the traffic efficiency of part of the hubs, which can achieve ideal service level of road network with the optimal travel cost. This paper can provide certain reference for similar project.
