Pedestrians were detected on the sidewalk at an indoor parking garage exit using two Microwave Sensors Corp., Model 1800 detectors. The sensors were directional and turned on the eyes and illuminated the appropriate pedestrian symbol depending on the direction that pedestrian was approaching. The use of this ITS device decreased the percentage of drivers that failed to look in the direction of approaching pedestrians from 25% to 6.4% and increased the percentage of drivers yielding to pedestrians from 58% to 82%. The use of the device was also associated with a reduction in vehicle exiting speed and motor vehicle/pedestrian conflicts.
