COORDINATION OF TRAFFIC SIGNALS WITH RAILROAD GRADE CROSSING PROTECTION

Preemption sequences for various geometric conditions are presented in figures, and criteria for adequate grade crossing preemption and coordination are listed. The preemption sequences illustrated here cover signalized intersection of 4-lane undivided roadways - 2 phase operation; signalized intersection of 4-lane undivided roadways with railroad bisecting intersection - 2 phase operation; signalized intersection of 2-lane roadways with railroad bisecting intersection - 2 phase operation; and signalized intersection of 2-lane roadways with a railroad crossing on two approaches - 2 phase operation. The recommendations presented here were developed after evaluation of information from a literature review and from contracts with engineers from states, counties, and major cities.
