【摘要】:以國(guó)際平整度指數(shù)為中間指標(biāo),構(gòu)建路面行駛質(zhì)量指數(shù)與出行時(shí)間費(fèi)用之間的定量關(guān)系,給出路面行駛質(zhì)量變化帶來的當(dāng)量出行時(shí)間費(fèi)用差異.通過已有四分之一車模型的動(dòng)力方程,以高速公路為研究對(duì)象,對(duì)選定的50條道路在13個(gè)速度下的國(guó)際平整度指數(shù)進(jìn)行仿真計(jì)算.以國(guó)際平整度指數(shù)為中間指標(biāo),利用已有不同速度下平整度指數(shù)與行駛質(zhì)量指數(shù)的關(guān)系,給出每條道路在不同速度下的行駛質(zhì)量指數(shù).以80km·h-1的路面行駛質(zhì)量指數(shù)為基準(zhǔn),給出了路面行駛質(zhì)量指數(shù)差異與達(dá)到相同行駛質(zhì)量時(shí)的行駛車速差異之間的關(guān)系.分析結(jié)果表明,兩者具有良好的相關(guān)性.路面行駛質(zhì)量變化對(duì)出行時(shí)間費(fèi)用有顯著影響,在出行選擇行為分析、道路維修養(yǎng)護(hù)效益評(píng)估等相關(guān)研究中應(yīng)予以考慮.
[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.
