The Applications and Methods of Pedestrian Automated Detection

Pedestrian safety is a primary traffic issue in urban environment. The use of modern sensing technologies to improve pedestrian safety has remained an active research topic for years. The applications and difficulties of pedestrian automated detection were investigated, and the existing sensing technologies such as piezoelectric sensor, infrared sensor, ultrasonic sensor, microwave radar, laser scanner and computer vision were assessed for their suitability to pedestrian automated detection, their advantages and limitations were analyzed. As any one particular type of technology may have difficulties meeting all necessary requirements in various conditions, It is pointed that that a complete and reliable sensing system for pedestrian detection can benefit from the combined use of multiple sensors.
