高速公路枢纽互通交织区长度计算分析

Calculation and Analysis of Length of Expressway Interchange Hub and Interweaving Zone

高速公路枢纽互通交织区是道路通行的瓶颈,严重影响道路的通行和行车安全,增加交织区长度是提高道路通行能力和服务水平的有效措施。文中根据现有研究成果,给出了一种交织区长度的计算方法,并结合实际工作中的设计实例进行计算分析。

Interweaving zone of expressway interchange hub is the bottleneck of road traffic,which has a serious impact on road access and traffic safety.Increasing the length of the interweaving zone is an effective measure to improve the traffic capacity and service level of the road.According to the existing research results,a calculation method of the length of the interweaving zoneis put forward,and the calculation and analysis are carried out based on the design examples in practical work.
