TABLE OF CONTENTS Avoidance of collisions with vulnerable road users (pedestrians, bicycles, and motorcycles) was discussed in Chapter 7 for vehicle-based sensor systems. Additionally, a unique cooperative approach within the European PROTECTOR project is being explored. In addition to direct-sensing approaches, PROTECTOR has investigated enhancing the performance of vehicle-based systems by means of transponders or microwave/optical reflectors carried by vulnerable road users. These techniques are being evaluated at test sites.
