摘　　要：为了确定城市中心区的合理停车泊位数量,使之既能满足基本出行需要,又能抑制过量出行造成路网拥堵,首先对停车泊位有限供给条件下驾驶员出行行为进行了分析,划分了不同驾驶员属性以反映不同驾驶员的出行意愿与决策特征,并在此基础上构建了最佳泊位规模优化模型,以使得在道路网络最大容量允许范围内可满足的停车总需求最大并做到泊位利用最大化.介绍了模型求解算法,数值算例表明,通过该模型的优化可确定城市中心区的最佳停车泊位数量,为停车需求管理提供科学依据.In order to determine the reasonable number of midtown berths to not only satisfy the need of basic trips but also be able to restrain excessive trips causing network congestions,an analysis was first made of the trip behavior of drivers under a restricted supply of parking berths,and different attributes of drivers were defined to characterize the trip desirability and decision behavior of different drivers.Then,a model for optimizing the number of parking berths was constructed to satisfy the maximum parking demand and to maximize berth utilization within the maximum capacity of road network.The solution of the model was introduced.A numerical example shows that with the model the optimal number of parking berths of the midtown can be determined,which can provide scientific bases for parking demand management.
