摘要: 为合理确定城乡接合部道路交通事故的影响范围,以重力模型为基础,构建城乡接合部影响 带模型。分析城乡接合部道路交通事故辐射范围的4 个影响因素:交通流特征参数、交通组成、道 路横断面、土地利用。对交通事故影响持续时间进行分析计算,进而基于烟羽模型构建城乡接合部 道路交通事故辐射范围模型。最后,根据昆明市兴呈路事故数据验证了模型的可行性。同时为便于 实际应用,建立了道路交通事故辐射范围分析系统,可得到事故在时间和空间上的动态影响范围。

Abstract: In order to identify impact area of road traffic accidents in urban-rural fringe, this paper develops an impact zones model based on gravity model. Four influential factors on the coverage of road traffic accidents in urban- rural fringe are discussed, such as characteristics of traffic flow, traffic composition, roadway cross-section, and land-use patterns. Moreover, the impact duration is generated through the developed plume model. The accidents data of Xingcheng road, Kunming is adopted as a case study to verify the feasibility of proposed model. The paper establishes an analytical system for detecting impact area within the road traffic accidents so as to generate the spatial/temporal impact of road traffic accidents.

Keywords: traffic engineering; road traffic accidents; urban-rural fringe; coverage scope; plume model
