Mechanism analysis of traffic accident prone points based on The Spatial Durbin Model

Abstract

The significant increase of freight traffic related collision accidents has aroused people's increasing concern about road safety. Using data from California, this paper studies the spatial relationship between freight related traffic accidents and low-income and minority communities. The study found that household income and minority population were significantly correlated with the density of freight related crashes and freight related crashes that led to serious casualties. Compared with areas with high-income groups, areas with low economic status, such as blacks and Asians, are more than 119% more likely to have traffic accidents. Among them, areas with black populations are more than 39% more likely to have traffic accidents than areas with Asian populations. The results show that freight related collisions are affected by spatial inequality.
