According to Traffic Police, about 35% of deaths and more than 50% of injuries caused by traffic collision in the roads of Tehran are among drivers and car occupants. This study was conducted to determine areas with the highest number of traffic collisions and perform spatial analysis of traffic collisions involving drivers in Tehran during April 2014 to March 2017.
The present study was a cross-sectional and descriptive-analytic research. In this study, all traffic collision that driver was accounted (100 percent or less) for crash occurrence which resulted in the death of at least one person (driver, pedestrian or passenger) were included in the analyses. Geographic information system software was used to show spatial distribution of events from zoning maps. Moran index was used in the mathematical analysis in order to determine the distribution pattern of the events from and Getis-Ord G statistics was applied to analyze the hot spots (high risk points).
A total number of 519 traffic collisions were investigated in this study. Moreover, 283 cases (54.5%) of the incidents took place in direct routes and 236 cases (45.5%) occurred at intersections. The most frequent events were in the region 4 (57 cases) and the least frequent events were reported in the region 10 (6 cases). Moran statistics show that the distribution of the studied events significantly follows the cluster pattern (p<0.001).
The northeastern and northwest margins of Tehran are the most prone areas for drivers involved with traffic collisions leading to death. Most traffic collisions leading to death take place at highways located at the entrance and exit points of Tehran and highways in regions 2 and 5.
据交通警察称，德黑兰道路上发生的交通事故中，约有 35%的死亡事故和超过 50%的人员受伤事故涉及驾驶员和汽车乘客。本研究旨在确定交通事故发生率最高的区域，并对 2014 年 4 月至 2017 年 3 月期间涉及驾驶员的德黑兰交通事故进行空间分析。
本研究为横断面描述性分析研究。在本研究中，所有驾驶员全责或部分责任的交通事故，且事故导致至少 1 人（驾驶员、行人或乘客）死亡，均被纳入分析。地理信息系统软件用于从分区图显示事件的空间分布。Moran 指数用于数学分析，以确定事件的分布模式，Getis-Ord G 统计量用于分析热点（高风险点）。
本研究共调查了 519 起交通事故。此外，283 起（54.5%）事故发生在直线路段，236 起（45.5%）发生在交叉路口。发生频率最高的区域是 4 区（57 起），发生频率最低的区域是 10 区（6 起）。Moran 统计数据显示，研究事件的分布明显遵循聚类模式（p<0.001）。
德黑兰东北部和西北部边缘是驾驶员发生致死交通事故的高风险区域。大多数致死交通事故发生在德黑兰入口和出口处的高速公路以及 2 区和 5 区的高速公路上。
