【摘要】：由于经济的快速发展,我国机动车辆迅猛增加,交通需求不断膨胀,交通需求与交通供给之间矛盾日益突出,导致交通问题日益凸显,作为有效解决交通问题的智能交通系统(ITS)应运而生。先进的出行者信息系统(ATIS)是ITS重要的组成部分,能够为出行者在出行过程中提供准确、快捷的信息,因此ATIS对出行者的路径选择过程产生一定的影响,本文主要是研究在ATIS作用下出行者的路径选择模型及其算法。本文首先分析已有的路径选择原理和路径选择模型,以交通信息对出行者的基础上对原有路径选择模型加以改进,得出了符合ATIS作用下的路径选择模型：第一种是UE诱导策略下路径选择模型,第二种是SO诱导策略下的路径选择模型,并对它们进行求解,随之对ATIS下的路网可靠性进行了分析计算,最后以蚌埠市禹会区为例验证ATIS所占有的市场份额变化的情况下,该区域路网的运行情况,具体得出如下结论：(1)当车辆诱导系统所占有的市场份额不变时,随着流量的增加,主要路段和次要路段的流量都有所增加。就主要路段而言,在UE诱导策略下的分配流量要高于SO诱导策略下的分配流量。对于次要路段而言,SO诱导策略下的分配流量始终高于UE诱导策略下的分配流量。(2)对于主要路径的路段而言,随着市场份额的增加,其分配流量主要是先增大后减少；就处于次要路径的路段而言,随着市场份额的增加,其交通流量先增大后减少,然后再增大,ATIS所占有的市场份额为0.4是一个分界点。(3)随着市场份额变化,在UE和SO诱导策略下,其路网行程时间可靠性都发生变化。就整体而言,随着市场份额增大,在SO诱导策略下的行程时间可靠性始终大于在UE诱导策略下的。
[Abstract]:Due to the rapid development of economy, the rapid increase of motor vehicles in China, the continuous expansion of traffic demand, the contradiction between traffic demand and traffic supply is increasingly prominent, leading to increasingly prominent traffic problems.The Intelligent Transportation system (ITS), as an effective solution to traffic problems, emerges as the times require.The advanced traveller information system (ATIS) is an important part of ITS, which can provide accurate and fast information for travelers during the travel process. Therefore, ATIS has a certain impact on the path selection process of travelers.This paper mainly studies the path selection model and its algorithm under the action of ATIS.Firstly, this paper analyzes the existing path selection principle and path selection model, and improves the existing path selection model based on the traffic information.The path selection model under the action of ATIS is obtained: the first is the path selection model under the UE induction strategy, the second is the path selection model under the so induced strategy, and they are solved.Then the reliability of the road network under ATIS is analyzed and calculated. Finally, taking Yuhui District of Bengbu City as an example to verify the change of the market share occupied by ATIS, the operation of the regional road network is analyzed and calculated.The following conclusion is drawn: 1) when the market share of the vehicle induction system remains unchanged, the flow of the main section and the secondary section increases with the increase of the flow.For the main sections, the distribution flow under UE induction strategy is higher than that under so induction strategy.For the secondary section, the distribution flow under so inductive strategy is always higher than that under UE induction strategy. For the main route, with the increase of market share, the distribution flow increases first and then decreases;The reliability of road network travel time changes.As a whole, with the increase of market share, the reliability of travel time under so-induced strategy is always higher than that under UE induction strategy.
