道路交叉设计中应注意问题及优化措施

Problems and Optimization Measures Should be Paid Attention to in the Road Crossing Design

道路交叉设计是道路设计的重要组成部分,其目的是实现各不同方向道路的交汇与联络,保证交通的安全及畅通。中国道路交通事故发生率居高不下,道路交叉口更是事故多发区,这与复杂的道路交通环境和交叉口设计不当有很大关系。论文首先阐述了道路平面交叉设计中应注意的基本要求、控制因素、设置方法等内容;接着论述道路立体交叉设计中的适用范围、控制因素等问题;最后提出了道路交叉设计中应采取的几点优化措施,包含合理选材、加强联系、预测交通量等主要影响因素,以进一步完善道路交叉设计方案。

Road cross design is an important part of road design,its purpose is to realize the intersection and contact of roads in different directions,to ensure the safety and smooth traffic.The incidence of road traffic accidents in China is high,and road intersections are accident-prone areas.This has a lot to do with the complex road traffic environment and the improper design of intersections.This paper first expounds the basic requirements,control factors,setting methods of the road plane crossing design,and then discusses the applicable scope and control factors of road stereo cross design,and finally proposed the optimization factors,including reasonable material selection,strengthening contact,predicting traffic volume and other main factors,to further improve the road cross design scheme.
