在道路各项平纵面几何指标中,小客车交通条件下缩减行车道宽度的研究始终吸引着研究人员的关注。通过设置小客车专用车道或高速公路,既可满足小客车交通量猛增的实际需求,又可节约用地,是解决目前我国交通建设需求与土地资源有限之间矛盾的重要途径。本文旨在探索研究小客车交通条件下车道宽度对通行能力的影响,为后续的深入研究提供参照,并积累方法和经验。
In the geometric indicators of the flat surface of all roads, the study of narrowing the width of traffic lanes under the traffic conditions of passenger cars has always drawn the researchers’ attention. By setting up a dedicated bus lane or expressway for minibuses, it can not only meet the actual needs of surge in passenger cars but also save land, which is an important way to solve the contradiction between the current demand for transport construction and the limited land resources in our country. The purpose of this paper is to explore the impact of lane width on traffic capacity under the traffic conditions of passenger cars and to provide references for further research and to accumulate methods and experiences.
