摘要
由于路网内交通流的时变性与复杂性,固定不变的划分方案大大降低了信号控制系统的有效性与合理性.基于城市交叉口群的特点,对城市交通子区划分进行研究;分析研究国内外城市交通控制的文献资料,基于城市交通子区的交叉口群特性,提出交叉口群动态划分方法.以威海市菊花顶路干线各交叉口采集的数据对方法的实用性进行验证分析,结果表明交叉口群间进行良好的区域协调控制能够在很大程度上缓解交通拥堵现象,并可提高路网利用率.
Due to the time variability and complexity of the traffic flow in the road network,the fixed division scheme greatly reduces the validity and rationality of the signal control system.Based on the characteristics of urban intersections,this paper studies the urban traffic sub-district division,analyzes the literatures of urban traffic control at home and abroad,and puts forward the dynamic partitioning method of intersection group.By the specific case of analyzing the intersections of Juhuading Road in Weihai,it is convinced that the good regional coordination control between the intersections can alleviate the traffic congestion and improve the utilization rate of the road network to a large extent.
