Red Light Running Violations of Four Intersections in Colombo Suburban

Abstract

Four signalized intersections were selected which located in Colombo suburban, Battaramulla, Pelawatte, Thalawthugoda and Denzil kobbekaduwa. The observational survey was conducted for both peak and off-peak hours. Totally, 118,837 vehicles were observed and categorized them into three types; motor vehicles, motorcycles, and three wheelers. The Red Light Running (RLR) violation rate was 0.94% for motor vehicles, 2.44% for motorcycles, and 1.33% for three wheelers. The rate for motorcyclists was high in off-peak hours than peak hours. The RLR violation rate of motor vehicle drivers is lower than those for motorcyclists. The observed drivers were classified into two age groups: young and adult and more RLR violation rate was observed by young drivers than adults. Young drivers were found to be more likely to have risk-taking and adult drivers were found to be more likely to have opportunistic behaviors.
