城市信号交叉口公交优先及模糊控制策略

城市公共交通优先(公交优先)是公交优先发展的一个重要措施,对缓解交通压力及城市的可持续发展具有重大意义,公交优先信号控制的关键是信号交叉口的公交优先控制策略。概述了交叉口公交优先技术研究的现状,介绍了一种信号交叉口的公交优先模糊控制方法,引入相序优化器,并着重分析了基于相序优化的交叉口公交优先模糊控制策略。

Study of Urban Intersection Transit Priority and Fuzzy Control Strategy

Bus priority transit in urban is an important treatment for the development of bus priority.Bus priority at intersections is of great important to relax traffic pressure of urban and assure the city to develop persistently.The key of urban transit signal priority control is bus priority strategies at intersections.The paper briefly reviews the present situation of research on bus signal priority at intersections.A fuzzy traffic control theory of bus priority at intersections is presented,and a phase sequencer is introduced.Bus priority strategy at intersections based on phase sequencer has been discussed in this paper.
