Abstract

In this paper, we investigate some new dynamic phenomena of Braess's paradox in transportation networks when both the departure time and route choices are considered simultaneously. The classical Wardropian user equilibrium principle is used to characterize route choice behavior, and the traditional bottleneck models with deterministic queues are employed to describe user's departure time choice behavior. New Braess's paradoxes with dynamic user response have been found in respect to the point queue and physical queue assumptions, and the mechanisms of such paradoxes are analyzed in details. Furthermore, it is shown in a numerical example that a paradox may occur in network when physical queue assumption is made, but the paradox may not be found in network if the point queue assumption is adopted in the proposed dynamic traffic assignment model. Due to the significant difference between point queue and physical queue assumptions, spatial dimension of queues has to be considered carefully in dynamic traffic assignment models. Finally, some traffic management measures are suggested and examined to resolve the potential paradoxes, such as link closing, ramp metering, dynamic road pricing, lane partitioning, and adaptive traffic control etc.
同时出发时间和路线选择的动态交通分配中的Braess悖论
本文研究了同时考虑出发时间和路线选择的交通网络中布雷斯悖论的一些新的动态现象。采用经典的“衣橱”用户均衡原理描述路线选择行为,采用传统的具有确定性队列的瓶颈模型描述用户出发时间选择行为。在点队列和物理队列假设下,发现了具有动态用户响应的新Braess悖论,并详细分析了这种悖论的产生机制。此外,数值算例表明,在采用物理队列假设时,网络中可能出现悖论,而在本文提出的动态流量分配模型中采用点队列假设时,网络中可能不会出现悖论。由于点队列与物理队列假设存在显著差异,在动态交通分配模型中必须仔细考虑队列的空间维度。最后,提出并检验了一些交通管理措施,如封闭路段、匝道计量、动态道路收费、车道划分和自适应交通控制等,以解决潜在的矛盾。
