摘要
公路快速化改造过程中,原道路平面交叉口存在通行能力有限、事故率较高等问题,用立交来代替平交,对老路平交口进行立体化改造,将有效地缓解上述问题。归纳平交口立体化改造中道路的相交方式,选取典型的工程案例,进行车辆运行速度数据调查和分析,结合路段交通特征,总结各道路相交方式的安全问题。
In the highway express reconstruction process, the problems of limited traffic capacity and higher accident rate are existing at the grade intersection of original road. The interchange instead of the grade intersection and the three-dimensional reconstruction of old road grade intersection will efficiently solve the about problems. The article concludes the intersecting mode of road in the grade intersection three-dimensional reconstruction, analyzes the vehicle running speed data survey by a typical engineering case, and summarizes the safety problems of each road intersecting mode according to the traffic features of road section.
