ABSTRACT
This study aims to investigate significant contributing factors for crash frequencies and severities on rural two-lane highways and develop corresponding injury-prevention and mitigation strategies for safety improvements. With data from the Department of Statistics and the Department of Public Security of Heilongjiang, China, from 2006 to 2012, Principal component analysis (PCA) techniques are used to extract the crash patterns behind the data and explore various contributing attributes of crash occurrence. Based on the analysis of model estimation results, five strategic prevention and mitigation countermeasures are proposed: (1) education and training, (2) management, enforcement, and punishment, (3) engineering improvements, (4) emergency, (5) accident audit and safety assessment. This research contributes to enhance traffic safety performance on rural two-lane highways.
