摘　　要：Traffic crashes are a prominent cause of fatalities around the world.This study focuses on the dynamics of traffic safety by analysing factors influencing crash frequency during both nighttime and daytime conditions.Four years’data derived from the Fatality Analysis Reporting System(FARS)database were analysed statistically based on the negative binomial regression model,to identify the contributions of several factors affecting crash outcomes.The findings reveal significant related factors,including area type,roadway alignment,speeding-related factors,sex of driver,number of lanes,grade,surface type and weather conditions,that contributed to the expected crash frequency during both daytime and nighttime conditions.Through quantitative analysis,the extent to which each factor contributes to the expected crash frequency was determined,offering effective insights for policymaking to boost roadway safety.The findings highlight the necessity of implementing targeted strategies to minimize the risk of crashes by creating safer road environments.
