This recommended practice will provide guidance on Traffic Probe Use data to manufacturers that are either Transportation System Management (TSM) core or aligned entities. The recommended practice originates from prior work of the Society of Automotive Engineers (SAE) Dedicated Short Range Communication (DSRC) Technical Committee, as well as existing practices implemented by industry, academia and government. The recommended practice informs manufacturers and practitioners of message use and operation within an automated collection system involved in the orchestration of safe, efficient, and reliable movement of people and goods. The recommended practice for Traffic Probe Use and Operation will support practitioners through the definition of message structure, on-board processing and storage requirements, the operational preservation of vehicle anonymity, and message event management criteria.
Rationale: The rationale behind this recommended practice is to decrease the spatial density of trusted devices (RSU) required by an individual TSM operator to conduct business on a specific facility under management (FUM). This recommended practice will guide the entire TSM cohort, thereby providing opportunity for reallocation of RSU to a greater total number of FUM (e.g. intersections).
