摘要
依托阳江山外东至海陵大堤段公路工程,采用运行速度法对道路线形进行优化设计。传统设计速度法未考虑车速不断变化的实际情况,导致线元指标与实际速度不匹配,运行速度法充分顾及驾驶者的心理预期,具有人性化优势及科学性。介绍了协调性评价指标及运行速度法的应用流程,实践表明运行速度法能有效克服传统设计速度法的固有缺陷,对提高道路线形设计质量,提升交通安全具有重要意义。
Basing on the highway project from the east of Yangjiang Mountain to the Hailing embankment,the running speed method is adopted to design the line of the road in this paper. Without considering the actual situation of constantly changing speeds of the vehicles,the traditional design speed method makes the line element index not match the actual speed. However,the running speed method fully takes the driver’s psychological expectations into consideration, which is more humanized. Additionally, the coordinated evaluation index and the application process of the running speed method are introduced in this paper. Practice has proved that the running speed method can effectively overcome the inherent shortcomings of the traditional design speed method,and is of great significance for improving the quality of road alignment design and traffic safety.
