Abstract

Understanding the underlying structure of vehicle crashes is essential for improving safety on the roads. Past research has found that accident tend to cluster both spatially and temporally. This paper applied spatial, temporal and SPATIO-temporal techniques to investigate patterns of ROAD ACCIDENT in Karaj-Qazvin highway-Iran between 2009 and 2012, at different characters. Spider graphs were adapted to identify temporal patterns of vehicle crashes at different situation. The spatial structures of vehicle crashes were analyzed using Fuzzy Kernel Density and then result was compared with KERNEL DENSITY ESTIMATION. Comap was then used to demonstrate the SPATIO-temporal interaction effect on vehicle crashes and spatial pattern of accident at different characters. Characters that influence at spatial and temporal pattern of accident are: Time, Week day, Type of accident (Fatal, Injury and Non-Injury), Type of Collision (Vehicle with Vehicle, Vehicle with Pedestrian, Vehicle with Objects and Overturn), weather situation (Clean, Rain and Snow), Human Behavior (Hurry, Fatigue and Sleepy and Low Inattention). The results show significant differences in SPATIOtemporal patterns of ROAD ACCIDENT for various crash causes. The techniques used here have the potential to help decision makers in developing effective road safety strategies.
