Advanced Pedestrian-Assistance Systems

Advanced Pedestrian-Assistance Systems（APAS）is a pedestrian-side mechanism to protect pedestrians from traffic accidents. APAS roughly consists of two parts. The sensing part monitors the surrounding environment and actions of pedestrians and determines whether a traffic accident is likely to occur in the monitored situation. The notification part provides pedestrians with the information obtained from monitoring results in real time or postmortem. Several sensor and UI configurations for different users and use cases are now under consideration. Another feature of APAS is that it is designed to collaborate with external systems through communication. The APAS-sensed information on the actions and surrounding environment of pedestrians is shared with vehicles and infrastructure via communications networks such as cellular and V2X. All these work together to enable an accident-free transportation system.
