Vehicle-to-pedestrian (V2P) systems detect and communicate the presence of at-risk pedestrians or bicyclists through the use of augmented sensors and communication systems. Researchers at the FHWA Turner-Fairbank Highway Research Center (TFHRC) in McLean, VA developed a multi-functional Pedestrian Technology Test Bed, consisting of two signalized intersections spaced approximately 600 feet apart and a midblock crossing. The test bed was used to conduct an assessment of commercially available V2P technologies to identify their strengths and weaknesses and reveal their potential effectiveness for improving pedestrian safety. The three systems included in field tests were grouped into two different categories based on use of either vehicle-based or smartphone-based technology.
- Camera-Based Safety Device (Aftermarket) connected to the vehicle’s data bus, with cautionary and emergency alert levels
- Camera-and-Radar-Based Detection Original Equipment Manufacturer (OEM) system, with visual/auditory alerts and automated braking
- Smartphone-Based Pedestrian-to-Infrastructure (P2I) Application which provides pedestrians with real-time signal information at a crosswalk
