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

为了缓解城市高速公路的交通拥堵，提出了动态车道运营方法，即根据交通状况动态改变城市高速公路JCT合流路段的车道数。作为可行性研究，提出了一种基于交通模拟的性能评价方法，并以东京都高速公路为例进行了研究，通过驾驶模拟实验对其安全性进行了评价，总结了进一步研究的实施情况。

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.
