摘　　要：传统公路横断面布设通常不考虑慢行交通,伴随国家城镇化比率日益提升,二级公路因仅有两个车道,受慢行交通影响日益显现。通过对城镇区慢行交通归类,将其分为慢行车辆混合段、短途交通混合段、交叉路口密集段三种场合,研究三场合慢行交通行驶特点,分析对快速交通产生的影响,结合设计速度控制,提出快慢车道分隔、四车道物理隔离、四车道双黄线隔离三种二级公路设置慢车道横断面布置方案。研究保证行驶安全和满足公路服务水平。The layout of traditional highway transverse sections usually does not consider slow traffic.With the increasing urbanization rate of the country,second-class highway is increasingly affected by slow traffic because it has only two lanes.By categorizing slow traffic in urban areas into three scenarios:mixed sections of slow vehicles,mixed sections of short distance traffic,and dense sections of intersections,the characteristics of slow traffic in these three scenarios are studied,and the impact on fast traffic is analyzed.Three schemes of slow lane transeverse section layout for second-class highways are proposed,that are,fast and slow lane separation,four lane physical isolation,and four lane double yellow line isolation.Research is conductive to ensure driving safety and meet the level of highway service.
