基于停车视距的高速公路中央分隔带安全性分析

Analysis on the central dividing strip safety of highway on the basis of stopping sight distance

根据小客车的行驶特性,探讨了小客车在设置中央分隔带公路弯道内超车车道行驶时,司机视点的位置,研究了停车视距及横净距的计算方法,以深中通道深圳侧接线为例,对高速公路中央分隔带停车视距的安全性进行了分析,从而提高道路交通的服务质量。

According to driving features of small passenger car,the paper explores driver’s sighting location when the small passenger car drives on the overtaking lane within central dividing strip,studies the calculation methods of stopping sight distance and cross clearance distance,pressure-pad-force channel Shenzhen lateral connection for example,and analyzes the stopping sight distance safety of central dividing strip of the highway,so as to improve the road traffic serving quality.
