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

停车引导和信息 (PGI) 系统向汽车驾驶员提供停车场的位置、方向和可用性信息，以便重新分配停车需求并减少热门停车场的排队和拥堵。本研究旨在调查 PGI 系统的实际驾驶员行为，并改进带有停车场的交通网络模拟模型，以估计 PGI 系统的效果。通过对松山市（包括 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驾驶员比例相对较低，并且驾驶员没有尽可能地改变停车场选择行为。 Theis意味着，驾驶员的停车场选择可能存在一些实际限制，例如购物时间和地点限制。 PGI系统有望减少这些限制。行为分析的结果被纳入仿真模型中，该模型由三个子模型组成；需求子模型、绩效子模型和信息提供子模型。需求模型描述了驾驶员的停车场选择和路线选择行为。性能子模型计算车辆在网络和停车场中沿着需求模型给出的路线的移动。信息子模型提供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，留言板的位置应便于司机在更换首选停车场后可以使用。

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.
