公路交叉口合理间距研究

Study on reasonable distance between road intersections

结合《公路路线设计规范》,针对不同功能的公路对平面交叉的间距要求也不一样,分析了集散公路和地方公路平面交叉间距组成,并给出了相应的间距值,以期指导设计和施工时合理选取公路交叉口合理间距,从而减少或避免交通事故。

Combining with Road Route Design Rule, the thesis made an analysis on the composition of plane cross-distance of distributed high- ways and local roads, according to the different requirements of plane cress-distance for roads with different functions. And the oorresponding value of distance was given, which was expected to direct the selection of the reasonable distance between road intersections in designs and con- struetions, so as to reduce or avoid traffic accidents.
