摘要: 为分析随机动态交通网络中出行者的旅行选择与停车行为, 利用网络均衡原理和不动点理论, 建立了供需相互作用下的不动点模型, 提出了计划可靠度和停车可靠度指标, 并对随机动态交通路网的可靠性进行了评价。发现停车设施的位置和步行距离对出行者的计划可靠度和停车可靠度水平影响较大, 停车费相当时, 出行者将优先选择距离目的地近的停车设施; 在早晨上班高峰期, 距离目的地较远的停车设施的停车可靠度较高。分析结果表明: 提出的可靠度指标能有效地衡量一天中不同时段道路网络和停车设施的服务水平。Abstract: In order to analyze the travel and parking behaviors of commuter in stochastic and dynamic transport network, a fixed point model was set up by using network equilibrium rule and fixed point theory, and a schedule reliability and a parking reliability were put forward to measure the stability of the network. It is found that the location of parking facility and walking distance have significant influence on the levels of both the schedule reliability and parking reliability of commuter, specifically, commuters often park their cars at the nearer locations from their workplaces among multiple parking locations with the same parking charges; during traffic peak period in the morning, the parking reliability of farther location is higher than that of nearer location. Analysis result shows that the indices can effectively measure the service levels of road network and parking facilities in everyday different periods.
