PGIS 信息差异化显示模型

摘要

In light of parking accumulation and imbalance problems of traditional PGIS information display method,the paper develops information differentiation display model. Combining with actual traffic conditions,it guides parking demand cars. Through simulation computation,it com-pares information differentiation display model to traditional information simulation result,which shows that:the former can actively adjust parking demand distribution,effectively improve the service efficiency of unpopular parks. As a result,it avoids ineffectively traffic flow on the urban road.%针对 PGIS 传统的信息显示方法产生停车积聚和停车场需求冷热不均等问题，开发了信息差异化显示模型，并结合路段交通情况，对寻停车辆进行引导，通过模拟计算，对信息差异化显示模型和传统的同信息法模拟结果进行对比，信息差异化显示模型可以主动调节停车需求分布，有效提高冷门停车场的使用效率，从而减少因寻停而产生的无效交通流。
