Abstract
In developing countries, insufficient road-hierarchy planning, and control result in signalized intersections along mixed-traffic highways. Motorcycles’ red-light running (RLR), along with insufficient enforcement, are the major causes of collisions at these intersections. The objective of this study was to determine the efficacy of automated RLR control in this scenario. Signalized intersections along Thailand’s Friendship Highway, which runs through Khon Kaen City, were used as research locations. For evaluating changes, this study used an observational before-after design with a group comparison. The study collected data on the RLR behavior, RLR tickets, as well as frequency of collisions and injuries, both before and after the RLR control implementation. The results suggest the RLR reduced by 33.3%. Crash and injury rates decreased by 17.5% and 13.6%, respectively. However, long-term studies are necessary for evaluating the impact on the rate of fatal outcomes. These results demonstrate the effectiveness of the RLR control for traffic regulation and accident prevention in the context of a developing country.
