Abstract
Two-wheeler riders face a heightened risk of fatal and serious injuries due to their inherent lack of protection compared to occupants of other vehicles. Intersection-related crashes, in particular, have demonstrated a tendency to lead to more severe consequences. This study aims to investigate the determinants of two-wheeler crash severity at intersections in Kathmandu Valley, providing valuable insights into crucial aspects of two-wheeler safety at these locations.
Using a multinomial logit model, the analysis explores a range of contributing factors influencing the severity of two-wheeler crashes at intersections in Kathmandu Valley. Crash severity (minor injury, serious injury, and fatal injury) is used as the dependent variable while age, gender, driving under influence, over speeding, day and timing of crash, collision type, and intersection type are used as independent variables. The analysis employs coefficient estimates, significance levels, and Relative Risk Ratios (RRR) of the variables as the measure of comparisons, and uses “Fatal Injury” as the base category for comparison
