This document serves as an Operational Concept for the Transit Bus-Pedestrian/Cyclist Crossing Safety application. The purpose of this document is to provide an operational description of “how” the Transit Bus-Pedestrian/Cyclist Crossing Safety Warning application may operate. The Pedestrian/Bicycle Crossing Safety application will alert/warn transit bus drivers as needed based on transit vehicle’s intention of traveling across a crosswalk where pedestrians or bicycles may be present and assessed level of collision risk. The application allows messages to be sent to transit vehicle drivers via a driver-vehicle interface, providing an appropriate alert type, based on calculated level of collision risk. The Operational Concept discusses the following scenarios: • Scenario 1: Motor Bus traveling straight (Signalized intersection) • Scenario 2: Motor Bus turning (Signalized intersection) • Scenario 3: Motor Bus traveling straight (unsignalized intersection) • Scenario 4: Motor Bus turning (Unsignalized intersection) • Scenario 5: Motor Bus traveling straight (mid-block pedestrian crossing) This document is intended to convey at a high-level how the application may work, so others may design and implement systems in the future. As such, the Transit V2I Operational Concept documents are “generalized” and not specific to a geographic area, an operating entity (e.g., transit agency), existing systems that may be in place for a region, agency operating procedures, nor political environment.
