对HCM2000中有关立交匝道与主线分合流点服务水平测算方法的研习与工程实践

立交的分合流点通行能力分析是立交通行能力分析的重要组成部分,其中主线与匝道的分合流点是研究的主要对象。对于此类的研究文章较多,方法不一。该文根据新版的《道路通行能力手册》(简称HCM2000)所阐述的方法,结合国内立交设计的实际情况,以及工作中通常所使用的流量数据,对该方法进行简化、归纳,并运用于实际工程。

Study on Sub-confluence Point Service Level Calculation Method of Grade Separation Ramp and Main Line in HCM2000 and Its Engineering Practice

The sub-confluence point traffic capacity analysis of the grade separation is the important composed part of the grade separation traffic capacity analysis,in which the sub-confluence point of the main line and the ramp is the main object of the study.There are more these study articles,but the methods are different.Based on the methods set forth in the new edition of Highway Capacity Manual(for short HCM2000),and according to the practical design condition of grade separation in China and the volume data commonly used in the work,the article simplifies and sums up this method,and uses it into the engineering practices.
