SAE J2945/C_202206

Connected vehicles can provide data from multiple sensors that monitor both the vehicle and the environment through which the vehicle is passing. The data, when shared, can be used to enhance and optimize transportation operations and management—specifically, traffic flow and infrastructure maintenance. This document describes an interface between vehicle and infrastructure for collecting vehicle/probe data. That data may represent a single point in time or may be accumulated over defined periods of time or distance, or may be triggered based on circumstance. The purpose of this document is to define an interoperable means of collecting the vehicle/probe data in support of the use cases defined herein. There are many additional use cases that may be realized based on the interface defined in this document. Note that vehicle diagnostics are not included within the scope of this document, but diagnostics-related features may be added to probe data in a future supplemental document. This standard provides a mechanism for vehicles to communicate environmental and sensor data to central repository. Anticipated data and situations include mobility data (understanding delays), roadway condition monitoring, adaptive signal control monitoring, local map development (including work zones), fleet vehicle maintenance, and third-party data. This proposed standard defines requirements to support V2I probe data messaging in a connected vehicle environment. The focus is on information exchanges between the infrastructure and connected vehicles.
