摘要: 交通仿真模型在先进的交通系统管理、控制和优化中得到了广泛的应用,研究提出了先进的出行者信息系统ATIS的多用户路径选择仿真系统框架,根据ATIS环境下的不同出行者行为和信息属性,把出行者分为传统型TR、固定路径型PS、理性型BR、用户均衡型UE、系统最优型SO以及VMS型,运用基于仿真的DTA给出了各类出行者的路径诱导算法,开发了ATIS环境下的微观仿真系统TESS,并以杭州市中心区路网为例进行了仿真分析。精度分析表明,基于模拟的方法可以详细刻画ATIS环境下不同类型的出行者的路径选择行为;敏感性分析表明,当受导用户市场占有率为0.2左右时,整个交通系统的总效益最高。

Abstract: Traffic simulation models have been widely used in traffic system management,control and optimization.The model framework to evaluate the performance of Advanced Traveler Information System(ATIS) and dynamic driver route choice behavior is presented.According to the driver behavior and information,six types of driver route choice behavior are studied based on the simulation-based DTA (Dynamic Traffic Assignment) methods,Six types route selection algorithms are put forward and the micro-simulation model TESS (Tongji transportation nEtwork Simulation System) is programmed,meanwhile TESS is used in modeling the network in Hangzhou city.It is demonstrated that the simulation based approach can describe the complicated traffic situations under ATIS and the most benefits are gained when the guided users market penetration is 0.2.
