【摘要】：交通网络潜在瓶颈路段是随着需求变化将来可能会成为瓶颈的路段.准确识别出潜在瓶颈路段并进行优化管理,可以更好地适应未来交通需求的变化.基于交通网络储备容量模型,提出了交通网络潜在瓶颈路段识别方法,并设计了储备容量模型的求解算法.算例分析比较了现状需求和路网可容纳最大需求下的交通均衡流量模式.结果表明,不能简单地根据现状需求去推断潜在瓶颈路段,而论文提出的方法可以识别出路网达到最大需求时的潜在瓶颈路段.此外,利用交通网络储备容量模型设计了一种次要潜在瓶颈路段识别方法,次要潜在瓶颈路段是在优化潜在瓶颈路段之后随需求增长新出现的瓶颈路段.算例表明该识别方法具有一定的适用性.
[Abstract]:The potential bottleneck of traffic network is the road that may become bottleneck in the future with the change of demand. Identification of potential bottlenecks and optimal management can better adapt to the change of traffic demand in the future. Based on the traffic network reserve capacity model, a method for identifying potential bottleneck sections of traffic network is proposed, and an algorithm for solving the reserve capacity model is designed. An example is given to analyze and compare the traffic equilibrium flow model under the condition of the current demand and the maximum capacity of the road network. The results show that the potential bottleneck section can not be inferred simply according to the demand of the present situation, and the method proposed in this paper can identify the potential bottleneck section when the road network reaches the maximum demand. In addition, using the traffic network reserve capacity model, a method of identifying secondary potential bottleneck sections is designed. The secondary potential bottleneck sections are emerging with the increase of demand after the optimization of potential bottleneck sections. An example shows that the method is applicable to some extent.
