在综合考虑速度和线形为主的影响高速公路安全性各方面因素的基础上,对浏醴高速公路路线设计安全性进行了分析。分析结果表明:浏醴高速公路中设计直线长度均满足安全评价要求,但其中28个曲线路段,建议在曲线前方设置限速标志,以满足停车视距的要求;左线、右线无相邻路段运行速度协调性不良路段,路段间线形指标协调,衔接合理。
On the basis of comprehensively considering the various factors that affect the safety of expressway, such as speed and linearity, safety of route design of Liu-li expressway is analyzed. The analysis results show that the designed straight line length in Li-li expressway meets the requirements of safety evaluation. However, in 28 of the curve sections, it is suggested to set the speed limit sign in front of the curve to meet the requirement of parking line of sight distance; Bad coordination of road sections, coordination of linear indicators between road sections and reasonable connection.
