考虑竞争关系的公共停车场规模优化模型

Modeling Modification on Scale of Public Parking Lots Considering Competing Relationship

通过考虑公共停车场的竞争关系,对公共停车场的供应规模进行优化。首先分析影响公共停车场供应规模的主要影响因素,总结现有的单体公共停车场的规模计算方法,在此基础上考虑公共停车场之间的竞争关系,应用蚁群算法作为公共停车需求的分配方法,进一步建立公共停车场规模优化模型。最后,通过实例对模型的有效性进行验证,优化后单体停车场供应规模减少7%,有效避免公共停车设施的重复供应。

This paper is to modify the supply scale of public parking lots by considering the competition of public parking lots. To begin with the study, this paper analyzes the main factors influencing the scale of public parking lots and summarizes the existing calculating model on scale of public parking lots. On whose basis the scale calculation model of public parking lots is established considering the competing relationship, in the model parking choice probability influenced by service radius is considered using Ant Colony Optimization. Finally, the effectiveness of the model was well validated in an example in which the optimized parking space was decreased by 7%. The model could avoid the repetition of public parking facilities supplying effectively.
