چکیده
Speeding is one of the most leading causes of almost any road traffic crash; that can increase either crash frequency or intensity. As a well-known intelligent transportation system (ITS), automated section control average speed cameras can enhance the traffic safety through spot control and section control. Previous studies looked at how much crashes might be related to speed, but they didn't look into how cameras could change crash patterns. In this regard, the present paper aims to investigate section control speed cameras' safety effects on Qazvin-Karaj freeway crash variables., eight years of police-reported crash data (۲۰۱۱–۲۰۱۸) were analyzed using the Chi-square (χ۲) test of independence. The results indicated that regardless of crash variable type, there is a statistically significant relationship between the crash frequency variations and speed camera installation. However, Cramér's V measure degree of association showed an ignorable correlation between section control speed camera installation and crash intensity and crash time variations. However, this index depicted more significant but still marginal impacts of their installation on crash category and crash type, with Cramér's V values of ۰.۲۰۸ and ۰.۱۸۸, respectively. Applied research has cleared the effects of speed cameras on crash-related variables that can assist stakeholders in the decision-making process that help them toward prioritizing budget assignment to make road safer in view of speed management.کلیدواژه ها
