行人-非机动车慢行共享路段交通冲突及服务水平分析

Traffic Conflict and Service Level of Pedestrian and Non Motor Vehicle Slow Sharing Road Section

受红线宽度所限,部分城市道路采用了行人与非机动车共享空间的断面形式。近年来,共享单车、外卖快递发展迅猛,慢行共享空间中行人和非机动车相互影响,交通冲突显著增加。根据深圳市4条行人与非机动车共享路段上交通调查获取的数据,对交通冲突的类型和数量进行统计分析,采用模糊C均值聚类分析方法,提出基于交通冲突数的慢行共享路段服务水平划分方法,得到完整连续的基于冲突数的服务水平划分标准及状态描述表,可为慢行空间的规划设计和管理提供参考。

Limited by the width of the red line,some urban roads adopt the cross-section form of shared space for pedestrians and non motorized vehicles.In recent years,shared bicycles and takeaway express delivery have developed rapidly,the pedestrians and non motor vehicle in the slow-moving shared space interact with each other,and traffic conflicts have increased significantly.Based on the data obtained from traffic surveys on four pedestrian and non motorized vehicle shared lanes in Shenzhen,the types and quantities of traffic conflicts are statistically analyzed.Using the fuzzy C-means clustering analysis method,a service level division method for slow shared lanes based on the number of traffic conflicts is proposed.A complete and continuous service level division standard and state description table based on the number of traffic conflicts are obtained,which can provide reference for the planning,design and management of slow-moving space.
