THE EFFECT OF ADVANCED WARNING FLASHERS ON RED LIGHT RUNNING--A STUDY USING MOTION IMAGING RECORDING SYSTEM TECHNOLOGY AT TRUNK HIGHWAY 169 AND PIONEER TRAIL IN BLOOMINGTON, MINNESOTA

Advanced warning flashers, which provide advanced warning to the motorist on high-speed approaches that the signal system will be turning yellow during their approach, are used by the Metro Division of the Minnesota Department of Transportation (MnDOT). They are used as an additional dynamic signing tool available for specific signalized intersections that have a combination of documented accident, sight line, isolated, and problematic operation. This study used Motion Imaging Recording System (MIRS) technology to collect data on the number, vehicle speed, vehicle type (cars or trucks), elapsed time into the red period, and time of day vehicles ran the red period of the southbound approach of the trunk highway signal system at U.S. Trunk Highway 169 and County State Aid Highway 1/Pioneer Trail in Bloomington, Minnesota, both before and after the installation of the advanced warning flashers. The intent of the study is to evaluate the effectiveness of advanced warning flashers at this location. While earlier studies within MnDOT have investigated and evaluated the operation of advanced warning flashers, MIRS technology provides large amounts of reliable data on red light running that were previously unavailable.
