本研究探讨洛杉矶市汽车碰撞的空间分布，并分析影响汽车碰撞风险的社会和物理因素。更具体地说，这项研究调查的社会人口，土地上升，密度，城市形态和交通特征对行人碰撞率的影响。我们首先提供了一个探索性的空间和统计分析的行人碰撞数据在城市的洛杉矶，以确定碰撞的频率和社会人口和土地利用特征之间的初步关系，在人口普查区的水平。这种聚合水平的分析点主要集中的行人碰撞数据，用于在研究的第二阶段，更定性和详细的分析，具体的案例研究的交叉口与高频率的行人碰撞。
This research explores the spatial distribution of pedestrian-automobile collisions in Los Angeles and analyzes the social and physical factors that affect the risk of getting involved in such collisions. More specifically, this Study investigates the influence of socio-demographic, land rise, density, urban form, and traffic characteristics on pedestrian collision rates. We first provide an exploratory spatial and statistical analysis of pedestrian collision data in the city of Los Angeles to identify preliminary relationships between the frequency of collisions and socio-demographic and land use characteristics at the census tract level. This aggregate level analysis points to major concentrations of pedestrian collision data which are used at a second stage of the research for more qualitative and detailed analysis of specific case studies of intersections with high frequency of pedestrian collisions.
