【摘要】：城市下穿隧道是公路隧道的一种,由于城市道路隧道在城市道路中修建时一般具备下穿的性质,所以本文将之称为城市下穿隧道。近几年来,随着城市的不断扩大,发展的速度加快,对城市交通的要求也越来越高,因此城市下穿隧道被大量修建。城市下穿隧道的修建对减少城市道路用地、缩短行车里程、疏导城市交通都有积极的作用。然而近年来城市下穿隧道中的交通事故有增多的趋势,由于城市下穿隧道相对闭塞,又位于城市中心,当发生交通安全事故时,一方面事故处理难,容易引发二次事故,另一方面又会给城市中心带来污染,以城市下穿隧道为对象进行专门的交通安全研究是必要而迫切的。鉴于已有城市下穿隧道交通事故统计和安全研究较少,本文在分析城市下穿隧道与普通公路相比的特点及交通事故特性的基础上,通过对全国城市隧道交通事故数据和成都市下穿隧道交通事故数据进行分析,研究下穿隧道事故时间和空间分布特征、形态特征和车辆类型特征,并在此基础上分析交通事故影响因素,获取城市下穿隧道交通事故影响因素层次图,然后在对城市下穿隧道事故多发点定义的基础上,利用基于SPSS软件的主成分分析法和线性加权评价法来分别为隧道事故多发点进行鉴别,并根据主成分分析法的特性,改进了适合于城市下穿隧道交通事故主要影响因素鉴别的方法,随后利用成都市2011年134起城市下穿隧道交通事故数据进行了实证分析。在文章的最后,提出了基于影响因素和事故多发点鉴别结果的交通安全管理措施。
[Abstract]:The urban underpass tunnel is a kind of highway tunnel. Because the urban road tunnel is built in the city road, it usually has the property of the underpass, so this paper calls it the urban underpass tunnel. In recent years, with the continuous expansion of the city, the speed of development is accelerating, and the demand for urban traffic is becoming higher and higher, so the tunnel under the city has been built a lot. The construction of the tunnel under the city plays an active role in reducing the urban road land, shortening the mileage of the traffic and guiding the urban traffic. However, in recent years, the number of traffic accidents in urban underpass tunnels is increasing. Due to the fact that the urban underpass tunnels are relatively closed and located in the center of the city, when traffic safety accidents occur, on the one hand, it is difficult to deal with accidents, which can easily lead to secondary accidents. On the other hand, it will bring pollution to the city center, so it is necessary and urgent to study the traffic safety through the tunnel under the city. In view of the fact that there are few studies on traffic accident statistics and safety of urban underpass tunnel, this paper analyzes the characteristics of urban underpass tunnel compared with ordinary highway and traffic accident characteristics. Based on the analysis of the traffic accident data of the national urban tunnel and Chengdu underpass tunnel, the distribution characteristics of time and space, the morphological characteristics and the vehicle type characteristics of the underpass tunnel accident are studied. On the basis of analyzing the influencing factors of traffic accidents, the hierarchy map of traffic accident factors in urban underpass tunnel is obtained, and then, based on the definition of the frequent spots of traffic accidents in urban underpass tunnels, The principal component analysis (PCA) and linear weighted evaluation (LWE) based on SPSS software are used to identify the accident prone points respectively, and according to the characteristics of the principal component analysis (PCA), This paper improves the identification method suitable for the main influencing factors of urban underpass tunnel traffic accidents, and then makes an empirical analysis based on the data of 134 urban underpass traffic accidents in Chengdu in 2011. At the end of the paper, traffic safety management measures based on influencing factors and identification results of accident-prone spots are put forward.
