道路平面交叉的方格网立面设计的研究

在城市道路中,由于道路的纵横交错而形成很多的交叉口。交叉口是道路的咽喉,车辆和行人都要在交叉口处汇集通过。道路交叉口在车辆和行人较多的时段,经常会出现交通阻滞的情况,也容易发生交通事故。因此,正确地设计道路交叉口并合理地组织交通,减少车辆在道路交叉口停留的时间,并保证车辆行驶安全和提高交叉口的通行能力,具有很重要的现实意义。笔者谈谈在道路平面交叉设计过程中一些粗浅的看法,希望能抛砖引玉,进一步优化设计,提高道路交叉口的通行能力。

A Study of Elevation Design of Square Grid of Road at Grade Intersection

There are a number of crossroads at city road grid,because the roads are arranged in a crisscross pattern. Crossroad refers to the key link to roads,where the vehicles and pedestrians have to pass by.During the peak time,many vehicles and pedestrians usually cause traffic jam and accidents.In this case,rightly designing crossroads and reasonably organizing the traffic can reduce the time that vehicles stay at the crossroads and make sure vehicles＇ safety and improve the crossroads＇ passing capacity,which are meaningful in reality.The author puts forward some ideas on the design of road at grade intersection,hoping they would serve as a modest spur to induce others to come forward with this valuable contribution and further optimize the designs to improve the roads＇ passing capacity.
