Abstract

To study the influencing factors of the implementation effect of the expressway directional lanes, and also to analyze the importance of different influencing factors on the implementation effect of the directional lanes, this paper explores the degree of influence of four influencing factors, namely, the number of lanes, the length of the interweaving area, the traffic volume and the proportion of exit flow by using the VISSIM, and constructs the mathematical relationship between multiple influencing factors and the proportion of average speed improvement by using the multivariate nonlinear regression The model was used as an example to analyze the section of Fuxingmen Bridge on the West Second Ring Road in Beijing. The results show that the number of lanes, the length of the interweaving area, the traffic volume and the exit flow ratio all have significant effects on the implementation of the expressway directional lanes, and the exit flow ratio is the most important influencing factor, followed by the traffic volume, the number of lanes and the length of the interweaving area. The results of the study provide a theoretical basis for further research on the setting of expressway directional lanes.
