Transit Vehicle-to-Infrastructure (V2I) Applications: Near Term Research and Development; Transit Bus Stop Pedestrian Safety Application: Operational Concept

This document serves as an Operational Concept for the Transit Bus Stop Pedestrian Safety application. The purpose of this document is to communicate user needs and desired capabilities for and expectations of the Transit Bus Stop Pedestrian Safety application. This document also serves to build consensus among transit user groups and stakeholders concerning these needs and expectations. The Transit Bus Stop Pedestrian Safety application will alert nearby pedestrians indicating the transit vehicle’s intention of pulling into or out of a bus stop. The application allows messages to be sent from transit vehicles to instrumented transit stops that in turn provide audible or visual alerts to pedestrians in the vicinity of a bus stop. This Operational Concept describes how the application applies to motor buses; however the application is also applicable to other transit types such as light rail. Three scenarios are described, including: Scenario 1. Motor Bus Approaching the Transit Bus Stop; Scenario 2. Motor Bus Departing from the Transit Bus Stop; and Scenario 3. Warning to Pedestrians of Oncoming Vehicles when Alighting the Motor Bus at the Transit Bus Stop, 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 Vehicle-to-Infrastructure (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.
