A Review of ITS-Based Pedestrian Injury Countermeasures


Crashes between motor vehicles and pedestrians caused at least 4,882 deaths and about 78,000 injuries in 2001 in the United States. In recognition of these troubling statistics, many public and private institutions look to Intelligent Transportation Systems (ITS) technologies. Few resources are available to provide a comprehensive summary of the effectiveness of these options. This report reviews previous scientific evaluation of red light enforcement cameras, illuminated walk signal push buttons, automated pedestrian detection systems for traffic signals, flashing crosswalk lights, countdown signals, and animated eyes. The research and policy implications of these summaries provide guidelines for future research as well as a practical outline of options for transportation planners.
