摘要: 为了预防交通网络的过饱和堵塞,定义了过饱和网络相邻交叉口关联度,给出了初始拥堵区域的确定流程,提出了以关键交叉口( 交通需求超过通行能力的交叉口) 为中心的多层边界控制策略,动态确定控制边界,将超过通行能力的车辆控制在多层边界路段上.与单层边界控制策略相比,多层控制策略能够充分利用拥堵区域内路段的存储能力,解决边界路段的排队溢出问题,缩小拥堵影响范围,有效减低停车延误和停车次数.案例结果表明,文中方法是可行的.

关键词: 交通控制, 过饱和网络, 主动控制, 排队溢出

Abstract:

In order to prevent the oversaturated network from queue spillback,the oversaturated correlation degree of neighboring intersections is defined and the process of determining the initial congestion area is proposed. Then,a multi-layer perimeter control strategy,which takes the key intersection with excessive traffic demand as the center,is established. With this strategy,the control perimeter can be dynamically determined and the vehicles are
limited in the multi-layer perimeter links when the traffic demand exceeds the network capacity. The results show that,as compared with the single-layer perimeter control strategy,the proposed strategy is more feasible because it fully uses the storage capacity of links in the oversaturated area, avoids the queue spillback of perimeter links,reduces the congestion coverage,and effectively decreases the stop delay and frequency.

Key words: traffic control, oversaturated network, active control, queue spillback
