【摘要】：以国际平整度指数为中间指标,构建路面行驶质量指数与出行时间费用之间的定量关系,给出路面行驶质量变化带来的当量出行时间费用差异.通过已有四分之一车模型的动力方程,以高速公路为研究对象,对选定的50条道路在13个速度下的国际平整度指数进行仿真计算.以国际平整度指数为中间指标,利用已有不同速度下平整度指数与行驶质量指数的关系,给出每条道路在不同速度下的行驶质量指数.以80km·h-1的路面行驶质量指数为基准,给出了路面行驶质量指数差异与达到相同行驶质量时的行驶车速差异之间的关系.分析结果表明,两者具有良好的相关性.路面行驶质量变化对出行时间费用有显著影响,在出行选择行为分析、道路维修养护效益评估等相关研究中应予以考虑.
[Abstract]:Taking the international smoothness index as the intermediate index, the quantitative relationship between the road quality index and the travel time cost is constructed. The difference of equivalent travel time cost caused by the change of pavement driving mass is given. Through the dynamic equation of the existing 1/4 vehicle model, the expressway is taken as the research object. The international smoothness index of 50 selected roads at 13 speeds is simulated and calculated. With the international smoothness index as the intermediate index, the relationship between the smoothness index and the driving mass index at different speeds is used. The driving mass index of each road at different speeds is given. The road quality index of 80km 路h ~ (-1) is taken as the benchmark. The relationship between the difference of road quality index and the difference of driving speed at the same driving quality is given. The results show that there is a good correlation between them, and the change of road quality has a significant effect on the travel time cost. It should be considered in the analysis of travel choice behavior and the evaluation of road maintenance and maintenance benefits.
