摘要/Abstract

摘要： 为提高寒区城市道路行车的安全性，使交通设施发挥最大的功能和效用，实地采集了长春市亚泰大街、亚泰大街快速路、会展大街及吉林市吉林大街等4个路段的道路分隔设施护栏高度H、行车速度V与行车安全间距W数据；用SPSS软件及数理统计方法分析了W的概率分布，构建了寒区城市道路H、V与W的函数关系模型；用算例对模型进行了验证。结果表明：在H一定的情况下，与H相对应的W、V基本服从正态分布；W与V、H显著相关，三者之间具有线性关系；推荐了考虑安全、高效和经济性的，与H相对应的寒区城市道路行车安全间距最小值和舒适值。

Abstract: In order to improve the driving safety of urban road in cold regions and maximize the function and effectiveness of traffic facilities, the data of guardrail height H, vehicle speed V and driving safety distance W of road separation facilities in four road sections of Yatai Street, Yatai Street Expressway and Huizhan Street in Changchun city and Jilin Street in Jilin city were collected on the spot. The probability distribution of W was analyzed by SPSS software and mathematical statistics. The functional relationship model between H, V and W of urban roads in cold regions was constructed, and the proposed model was verified by an example. The results show that when H is constant, W and V corresponding to H basically obey normal distribution. W is significantly correlated with V and H, and there is a linear relationship among them. Considering safety, efficiency and economy, the minimum values and comfort values for driving safety distance of urban road in cold regions corresponding to H are recommended.

Key words: traffic engineering; driving safety distance; facility height; urban road in cold regions
