停车场内场交通仿真模型的建立及评价

Traffic simulation and evaluation of the interior of parking lots

基于PTV Vissim软件算法和建立模型的原则,结合停车场内驾驶行为特征,分析了单个车位和成组车位在2种常见停车模式下微观建立模型的方法,对比分析了多层停车楼整体和分层建立模型2种方式的优、缺点以及适用性。根据停车场交通运行特征,明确了停车场仿真评测目的,结合各项参数测试的条件和检测器的布设位置,验证了该方法的有效性,为内部交通组织方案比选及交通改善提供科学依据。

Based on algorithm and modeling principles of PTV Vissim,with driving behavior mode in parking lots considered,the micro-simulation methods of single parking stall and group stalls were explained.Overall modeling and layered modeling were introduced and compared as two method to model multi-stories parking garage from the view of advantages,disadvantages and applicability.Traffic engineering theory was inducted to analyze the features of traffic stream in parking lots.General targets of parking lot simulation were stated with a list of evaluation parameters;the evaluation condition and the proper position of detectors were suggested.With an example illustrated,the availability of the method above-methed was verified,so that it can be used to simulate and evaluate the traffic in the parking lot quantitatively with scheme prioritization and the improvement of the traffic bottleneck.
