The aim of this report is to suggest how to make signalized intersections safer, in particular in respect to crashes caused by red-light violations. The report includes a review of literature, analysis of crashes, and interviews with Maine drivers. One conclusion is that the drivers are completely unaware that there was a red light in about a quarter of the crashes caused by red-light running violations. One way of improving the safety of the location may be to replace it with a modern roundabout. Another conclusion is that signalized intersections should be vehicle actuated if possible or else coordinated with nearby signals. More enforcement by police or automatic surveillance are considered by the public the most effective ways to reduce red-light running. Finally, the most important factor in reducing red-light running frequency, as well as the number of serious crashes caused by red-light running, is never having a posted speed limit greater than 35 mph through a signalized intersection.
