In most countries, occurrence of traffic causalities is high in pedestrians. The aim of this study is to geographically analyze the traffic casualties in pedestrians in downtown Tehran city.
The study population consisted of traffic injury accidents in pedestrians occurred during 2015 in Tehran city. Data were extracted from offices of traffic police and municipality. For analysis of environmental factors and site of accidents, ordinary least square regression models and geographically weighted regression were used. Fitness and performance of models were checked using the Akaike information criteria, Bayesian information criteria, deviance, and adjusted .
Totally, 514 accidents were included in this study. Of them, site of accidents was arterial streets in 370 (71.9%) cases, collector streets in 133 cases (25.2%), and highways in 11 cases (2.1%). Geographical units of traffic accidents in pedestrians had statistically significant relationship with a number of bus stations, number of crossroads, and recreational areas.
Distribution of injury traffic accidents in pedestrians is different in downtown Tehran city. Neighborhoods close to markets are considered as most dangerous neighborhoods for injury traffic accidents. Different environmental factors are involved in determining the distribution of these accidents. The health of pedestrians in Tehran city can be improved by proper traffic management, control of environmental factors, and educational programs.
在大多数国家，行人交通事故发生率很高。本研究的目的是对德黑兰市中心行人交通事故进行地理分析。
研究人群包括2015年发生在德黑兰市的行人交通伤害事故。数据从交警部门和市政部门提取。为了分析环境因素和事故地点，使用了普通最小二乘回归模型和地理加权回归。使用赤池信息准则、贝叶斯信息准则、偏差和调整后的指标来检验模型的拟合度和性能。
本研究共纳入514起事故。其中，事故发生地点为干线街道的有370起（71.9%），集散街道的有133起（25.2%），高速公路的有11起（2.1%）。行人交通事故的地理单元与多个公交站点、十字路口数量和娱乐区域存在统计学上的显著关系。
德黑兰市中心行人伤害交通事故的分布情况不同。靠近市场的社区被认为是行人伤害交通事故最危险的社区。不同的环境因素参与了这些事故分布的确定。通过适当的交通管理、环境因素控制和教育项目，可以改善德黑兰市行人的健康状况。
