Red light running is a risky traffic violation leading to traffic conflicts at intersections that may result very serious injury. Crashes related to red light running compose a substantial part of urban road safety. It has been estimated that pedestrians’ relative crash risk is eight times higher when they cross an intersection at red light instead of green (or yellow) light. Another study estimated a 10 to 15 times increase in fatal crash risk for all transport modes due to red light running. Red light running is fairly scarce amongst drivers (a few drivers per 1,000 vehicles), but fairly frequent among cyclists and pedestrians (percentages may run up to over 50% at specific days, times and locations). Red light running is influenced by several factors, including age and gender, static and dynamic characteristics of the intersection, day and time, and weather. Most research has been done in busy, large metropolitan city areas in China, Europe and the USA. (Author/publisher)
