Fatal single vehicle crashes (FSVC) have been identified as one of the most serious road-related risks; therefore, it is necessary to investigate their potential risk factors. A number of studies have been conducted to suggest the major factors and the relevant intervention strategies of FSVC. However, most of these studies ignored the spatial heterogeneity in estimating relationships between FSVC and potential factors. The aim of the study is to identify spatial patterns of FSVC in an attempt to explain its relationship with the underlying possible factors in Western Australia. Two types of factors in relation to FSVC are investigated in this research: (1) road condition (slope, sealed, wet, curve, cross and speed limits) and (2) environmental factors (light condition and rain weather). Geographic weighted regression model is applied to identify relationships between the factors and FSVC hot spots. The results show that the impact from significant risk factors is different on rural and metropolitan areas; therefore, the ways of roads accident prevention, especially for the FSVC, should be different.
