摘　　要：公路沿线地块的开发程度高,对平交口的需求增大,但平交口密度的增加,会增加交通事故率。论文在综合交通安全和通行效率的前提下,研究了城镇化地区如何合理确定平面交叉间距、平交口合理渠化等问题,并结合案例进行具体分析。The development of land along the road is high,and the demand for flat interchange has increased.Under the premise of comprehensive traffic safety and traffic efficiency,this paper studies how to reasonably determine the horizontal intersection spacing and the rational channelization of the horizontal intersection in the urbanization area,and makes a specific analysis based on the case study.
