Study on the Implementation of Dynamic Lane Operation for MergingSections of Urban Expressway Network

点击翻译按钮获取中文摘要

In this study, dynamic lane operation, which dynamically changes the number of lanes of JCT merging sections of urban expressway depending on the traffic condition, was proposed to mitigate the traffic congestion of urban expressways. As a feasibility study, the following works were carried out: proposal of a performance evaluation method using traffic simulation, case study for Tokyo Metropolitan Expressway, evaluation of the safety by driving simulation experiment, and summarization of the further study for the implementation.
