摘要:

为探究积水条件下最优的路网恢复决策方案,考虑了积水深度的动态变化,构建了城市三车道路段元胞自动机仿真模型。通过改进车辆换道与位置更新规则,描述积水条件下的驾驶行为变化,并仿真积水对路段通行能力的影响;分析积水导致车辆在部分路段通行受限时交通流在路网上的分布状态变化,建立以累积路网性能指标最大化为目标的恢复决策优化模型,并采用遗传算法与Frank-Wolfe算法相结合的方式求解。选取Sioux-Falls网络对模型进行验证,结果表明:求解模型得到的恢复策略对路网性能的恢复效果优于传统基于出度和基于流量的经验恢复策略,提升程度分别为3.84%、2.02%;路段恢复顺序不仅要考虑路段的受损程度,还要考虑路网的交通需求分布;恢复资源的增加会显著缩短路网的恢复时间,但边际效用逐渐降低。

Abstract:

To explore the optimal road network restoration decision scheme under waterlogged conditions, a urban three-lane road sections cellular automaton simulation model was constructed considering the dynamic change of waterlogged depth. By improving the vehicle lane change and position update rules, the changes of driving behavior under waterlogged conditions were described, and the impact of waterlogged on road sections traffic capacity was simulated. The changes in the distribution of traffic flow on the road network caused by water accumulation leading to restricted passage of vehicles on certain road sections was analyzed, a recovery decision optimization model aiming at maximizing the cumulative road network performance index was established, and the genetic algorithm and Frank-Wolfe algorithm were combined to solve the problem. Sioux-Falls network was selected to verify the model,the results show that the recovery strategy obtained by the provided model has better effect on road network performance restoration than the empirical recovery strategies based on output and flow, and the improvement degree is 3.84% and 2.02%, respectively. The road section restoration order should not only consider the damage degree of the road section, but also consider the traffic demand distribution of the road network. The increase of recovery resources will significantly reduce the recovery time of the road network, but the marginal utility will gradually decrease.

Key words: transportation planning and management, urban road network, waterlogged, cellular automaton, decision optimization, bi-level programming model
