Light rail transit systems have become popular because of their relatively low cost; ability to operate both on and off city streets, with intermediate capacity for transporting passengers; and frequent stops in urban areas. Most LRT systems operate portions of their systems in city streets, within median strips and in transit malls. Successful operation of LRT systems in the urban environment depends on integrated light rail and traffic signal controls. The operation of LRT systems in shared right of way presents a situation for accidents because of other users (motorists, pedestrians, bicyclists) in the right of way. Many safety problems are the result of motorists' and pedestrians' failure to obey or understand traffic controls. The Metro Blue Line (MBL) is a 22-mi LRT system that operates from downtown Los Angeles to the city of Long Beach. Approximately half of the MBL route runs parallel to an existing Southern Pacific railroad right of way, travels at speeds of up to 55 mph, and traverses 28 at-grade street crossings in areas of high traffic volume. The MBL Grade Crossing Safety Program was initiated in March 1993 to evaluate various ways to discourage or prevent illegal movements being made by vehicles at grade crossings that are causing train and automobile accidents. The safety program includes four elements: enforcement, engineering, legislation, and bilingual public education.
