A Study on Crash Risk and Its Influencing Factors on Expressways

Mehr zum Buch

The study explores the interplay between geometric design, traffic flow, and ambient conditions in relation to crash occurrences. It introduces a Crash Risk Estimation Model (CREM) tailored for urban and intercity expressways, allowing for a comparative analysis of crash causes based on expressway type. CREM effectively predicts hazardous conditions and assesses the safety benefits of geometric design, identifying crash-prone areas as dependent on traffic conditions. This model serves as a valuable tool for evaluating and improving roadway safety.
