A Study on Crash Risk and Its Influencing Factors on Expressways

Více o knize

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.
