Physical Object: Personal Information Device

Personal Pedestrian Safety

Overview

'Personal Pedestrian Safety' improves pedestrian, cyclist, and other vulnerable road user safety by providing personal location information to the infrastructure that can be used to avoid collisions involving vulnerable road users. It may also alert the vulnerable road user of unsafe conditions, augmenting or extending information provided by signals and signs. The information provided and the user interface delivery mechanism (visual, audible, or haptic) can also be tailored to the needs of the user that is carrying or wearing the device that hosts the application.
