Abstract:
Aiming to resolve the complex traffic environment of a ten-lane expressway, considering the factors of traffic volume and proportion of trucks, a comprehensive test design method is adopted herein. Further, the VISSIM traffic simulation software is used to perform simulation research using four lane-management schemes. Using average speed, traffic capacity, and the number of conflicts as the evaluation indexes, the principal component analysis method is used to construct the lane management-scheme evaluation method. Based on the lane management-scheme scores obtained under multiple combined traffic conditions, the conditions applicable for different lane-management schemes of the ten-lane expressway are proposed. The results show that for the ten-lane expressway,when the traffic volume is≤1 000 pcu/(h·lane), trucks should be prohibited from entering the far-left lane and when the traffic volume is >1 000 pcu/(h·lane) and the proportion of trucks is ≤30%, trucks should be prohibited from entering the three lanes on the left.Further,when the traffic volume is >1 000 pcu/(h·lane) and the proportion of trucks is >30%, trucks should be prohibited from entering the two lanes on the left.
Key words: ten-lane expressway, lane management, principal component analysis, traffic volume, proportion of trucks
