双层平面交叉在城市道路交叉口中的应用研究

Application of the double-crossing in the crossing of urban road

通过对城市道路平面交叉以及立体交叉的型式、占地、造价以及通行能力分析的基础上发现上述两者在城市道路交叉口中都存在一定的局限性,于是提出了双层平面交叉的概念,并对双层平面交叉的型式以及其设置的必要性、可能性、应用范围以及运用前景等进行了深入分析,认为其是城市道路交叉型式的又一补充.

According to the analysis of the form,the occupying land area and the traffic capacity between urban crossing and interchange,some limitations were found in both forms of the urban road.The concept of the double-crossing was put forward and its necessity,possibility,application and prospect were further analyzed.It is regarded as a supplement to the form of urban road crossing.
