摘要
针对四车道高速公路不能满足交通需求迅速增加的状况,对四车道高速公路改为准六车道的优势、技术方案进行分析,通过对准六车道高速公路通行能力、服务水平的研究,认为准六车道高速公路可以在节约土地的基础上,较大地提高高速公路通行能力,对促进公路交通的可持续发展具有极大的现实意义。
The four-lane expressway can not meet the rapidly increasing traffic demand.On this basis,it makes some research on the advantages and technical solutions to the change of four-lane expressway to quasi-six-lane.Through studying the traffic capacity and service level of quasi-six-lane expressway,it is concluded that quasi-six-lane,which is land saving,is of great help to enhance the capacity of expressway and has great practical significance for the sustainable development of highway traffic.
