Tracking heading angle especially at or from stationary position is key for pedestrian safety, e.g., for smart cross system and pedestrian collision mitigation system. It provides pedestrian-to-vehicle (P2V) platform. It deploys smart phones or mobile devices, equipped with DSRC (Dedicated short range communication) support, to act as beacons for pedestrians: Phone can alert driver to pedestrian presence in path; Pedestrian Basic Safety Message (BSM) can aid awareness for vehicles; It can be used for bicycles, as well. It also provides pedestrian-to-infrastructure (P2I) platform. Smart phone, through DSRC/cellular, transmits pedestrian presence to crosswalks/signals: It enables advanced crosswalk lighting/warning scheme; It enables bundling of pedestrian presence to vehicles. In this presentation, we provide various examples and variations on these."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of tracking pedestrian heading angle using smart phones data for pedestrian safety applications","description":"This presentation provides methods to track pedestrians heading angle using smart phone data.
