市政道路交通事故易发路段的线形设计研究

Research on Alignment Design of Municipal High-risk Road Sections

市政道路作为城市交通事故发生的载体,在承担服务功能的同时,自身的缺陷也会导致交通事故的产生。结合城市交通事故的发生率,介绍了弯道下坡、视距不良、排水不畅及多交叉口4个区域的高危路段,并着重分析了所在区域在路线设计方面的不足,结合设计经验,对线形进行了研究分析,分别提出了改善对策。

As a carrier of urban traffic accidents, the own defects of municipal roads can also lead to the traffic accidents while undertaking the service functions. Combined with the incidence of urban traffic accidents, this paper expounds the high-risk sections of the four areas of curved downhill, poor visibility, impeded drainage and multiple intersections, and analyzes the shortcomings of route design in the areas. Based on the design experience, this paper studies and analyzes the alignment, and puts forward the improvement countermeasures. The relative experience can be referred for the similar projects.
