地下停车场交通诱导信息设置优化
Optimisation of Traffic Guidance Information Settings in Underground Car Parks

为了改善城市化进程中地下停车场停车难、寻车难等现象，对地下停车场的区域划分、交通流线设计以及诱导标志设置等交通设计信息进行了优化设置。选取南京某地下停车场进行调研，在区域划分上提出基于使用者需求的分区方式，在交通流线设计上采用区域间主要道路应用双行交通，区域内部寻找车位的支线道路应用单行交通的设计方式，在诱导信息设计上提出诱导灯箱与墙面、柱面标志的趣味性优化方案。对交通流线的设计进行vissim仿真，证明该流线设计能有效减少地下停车场的交通冲突点，改善使用者的体验感。研究成果可为地下停车场区域的交通管理和规划设计提供理论依据。
In order to improve the phenomenon of parking difficulty and car-searching difficulty in under-ground parking lot in the process of urbanization, the traffic design information such as regional division, traffic flow design and induction sign setting was optimized. An underground parking lot in Nanjing were selected for investigation, a zoning method based on the needs of users in the regional division was put forward. In the design of traffic flow line, the design of two-way traffic is adopted for the main road application between regions, and the design method for one-way traffic is applied to the regional road applications in search of parking spaces. Besides, interesting optimization schemes in inducing light boxes, wall and cylinder signs in the design of induction information were proposed. The design of traffic flow line has been simulated by vissim, which proves that the design of the flow line can effectively reduce the traffic collision points in underground parking lots and improve the user’s experience. The research results can provide theoretical basis for traffic management, planning and design in underground parking areas.
