区域交通控制是智能交通系统的重要组成部分。本文将基于车道的优化方法推广到交通均衡网络，提高了信号控制网络的运行性能。我们制定了一种分解方法，同时优化车道标记和信号设置的信号控制网络，包括两个层次的优化。在交叉口层面，车道标记、控制序列和信号设置的其他方面针对单个交叉口进行了优化，而在网络层面，基于组的信号设置进行了优化，以考虑旅行者的重新路由特征和基于TRANSYT交通模型的信号协调效应，这是一个众所周知的评估信号控制网络性能的程序。我们用一个数值例子来证明所提出方法的有效性。
Area traffic control is an important element in Intelligent Transportation System (ITS). This paper extends the lane-based optimization method to a traffic equilibrium network, which improves the operational performance of signal-controlled network. We formulate a decomposition approach to simultaneously optimize the lane markings and signal settings for a signal-controlled network that comprises two levels of optimization. At the junction level, the lane markings, control sequence, and other aspects of the signal settings are optimized for individual junctions, whereas at the network level, the group-based signal settings are optimized to take into account the re-routing characteristics of travelers and signal coordination effects that are based on a TRANSYT traffic model, which is a well-known procedure for evaluating the performance of signal-controlled networks. We use a numerical example to demonstrate the effectiveness of the proposed methodology.
