摘要
针对当前农村交通安全存在的问题,分析了道路条件对交通安全的影响,并给出了各类道路条件的设计对策。基于农村公路线形不合理,路基、路面材质不合格、强度过低,边沟结构不规范,桥涵宽度不当和防护设施缺损,平面交叉口缺乏标线施划、信号控制及有效视距等道路条件,给出了影响交通安全的范围及程度。针对上述影响交通安全的道路条件,给出了相应的规范化设计对策,有助于改善农村公路在山区、桥涵以及平面交叉口的交通运行条件。
In order to solve the problem existing in the current rural traffic safety, the paper analyzed the influence of different road condition on traffic safety and proposed different design strategy of each road condition. Based on unreasonable routes of rural highway, unqualified material and low strength of subgrade and pavement, the non-standard structure of side ditch, the inadequate design of bridge and culvert width and the defect of protection facilities, the status of intersections which were lack of marking, signal control and effective horizon, the influence scope and degree of traffic safety were given. According to road condition effecting traffic safety above, the paper put forward the corresponding design countermeasures, which could improve the traffic operation condition of rural highway in mountainous rural areas, bridges, culverts and intersection.
