Factors associated with single-vehicle crash occurrences on Indonesian toll roads
Crashes on toll roads can be extremely hazardous, resulting in fatalities and serious injuries due to high speeds. Although multi-vehicle crashes are more commonly observed on Indonesian toll roads, single-vehicle (run-off-road) crashes should not be disregarded, as they also pose a significant risk of fatality. To identify the factors contributing to the occurrence of single-vehicle crashes on Indonesian toll roads, this study developed a crash prediction model that incorporates both geometric and traffic characteristics of toll roads, using a Negative Binomial regression model. The results indicate that higher average daily traffic, segments without roadside crash barrier, and segments with median concrete barrier are associated with a higher frequency of single-vehicle crashes. Conversely, the presence of a nearby ramp, bridge pillars, and segments with rigid pavement are associated with a lower frequency of single-vehicle crashes.
