FIXED ILLUMINATION FOR PEDESTRIAN PROTECTION. PHASE II
Phase II of this research consisted of the design and installation of specialized crosswalk illumination systems at seven locations in Philadelphia, Pa.; a determination of the improvement in visibility provided by these illumination systems; a determination of the improvement in driver detection of the improvement in driver detection of pedestrians at the specially illuminated crosswalks; a determination of pedestrian, driver and local resident attitudes toward crosswalk illumination; and a determination of the improvement in driver and pedestrian behavior under actual crossing situations. The major conclusions are (1) after installation of the specialized crosswalk illumination, illumination levels increased between 4:1 and 33:1; and the pavement luminance, ambient visibility (VI) and dynamic visibility (DVI) all significantly improved; (2) threshold detection increased by a almost 140%; (3) pedestrians, drivers and local resident attitudes toward the specialized illumination was extremely positive: a great majority felt safety, thought the lighting provided better visibility of pedestrians on crosswalks. The "AFTER" observational experiments indicated a safer behavior pattern at the illuminated crosswalks. This was demonstrated by (1) a longer mean search time; (2) a more complete search pattern in all directions in both first half and second half of the crossing; (3) a more distinct motivation and distraction; (4) greater use of the crosswalk area (fewer crossings outside of the crosswalk), especially in observations with potential pedestrian-vehicle conflict; and (5) brighter apparent clothing brightness.
