Dynamic Analysis of Drivers' Evaluation and Behavior for Parking Giudance and Information Systems

泊车指引及资讯（PGI）系统向车辆司机提供停车场的位置、方向和可用信息，以重新分配泊车需求，减少热门停车场的排队和挤塞。本研究旨在探讨PGI系统下驾驶员的实际行为，并改进带停车场的交通网络仿真模型，以评估PGI系统的效果。通过对松山市17个停车场的调查，研究了驾驶员对PGI系统的反应。尽管知晓率很高，但使用该系统的汽车司机的比例相对较低，而且司机的停车选择行为并没有像他们可能改变的那样多。这意味着司机的停车选择可能存在一些实际的约束，如购物时间和地点的约束。PGI系统有望减少这些限制。将行为分析结果纳入仿真模型，该模型由三个子模型组成；需求子模型、性能子模型和信息提供子模型。需求模型描述了驾驶员的停车选择和路径选择行为。性能子模型根据需求模型给出的路线计算网络中车辆的运动和停车情况。信息子模型提供了三种不同类型的可用性信息。比较了留言板在网络中的位置模式。我们发现，留言板的位置应该是让司机在更换第一选择的停车场后可以使用。

Parking Guidance and Information (PGI) systems provides location, direction and availability information of car parks to car drivers in order to redistribute parking demand and to reduce queues and congestion in the popular car park. This study aims to investigate actual drivers' behavior for PGI systems and to improve traffic network simulation model with car parks for estimating effects of PGI systems.Drivers' response to the PGI system was studied using the survey in Matsuyama city including 17 car parks. In spite of the high awareness rate, the percentage of car drivers who used the system was relatively low and drivers did not change car park choice behavior as much as they might be. Theis means that there might be some actual constraints for drivers' car park choice such as shopping time and place constraints. PGI systems are expected to reduce those constraints.The results of the behavioral analysis was incorporated into the simulation model, that consists of three sub models ; demand sub-model, performance sub-model and information providing sub-model. The demand model describes a driver's car park choice and route choice behavior. The performance sub-model calculates the movement of a vehicle in the network and car parks along the route given through the demand model. The information sub-model provides three different types of availability information. The location patterns of the message board in the network were compared. It is found that the message board should be located so that it would be available for drivers after changing the car parks of the first choice.
