道路工程中侧向余宽的常见问题及改进建议

Common Problems and Improvement Suggestions for Lateral Margin in Road Engineering

侧向余宽是指从行车道边缘至路旁障碍物所应保持的横向距离。因对侧向余宽的认识不足,侧向余宽缺失成为一些路段的常见问题,给道路行驶安全留下隐患。本文研究了驾驶行为对侧向余宽的需求,梳理了我国有关规范对侧向余宽的要求,分析了道路工程中侧向余宽的常见问题并提出了改进意见。

Lateral residual width refers to the lateral distance that should be maintained from the edge of the roadway to the obstacles along the roadside.Due to the lack of understanding of the lateral surplus,the lack of lateral residual width has become a common problem in some road sections,leaving hidden dangers to road safety.This paper studied the demand of driving behavior for lateral margin,combs the requirements of China's relevant norms for lateral mar?gin,analyzed the common problems of lateral margin in road engineering and put forward suggestions for improvement.
