3.1.3–Process Vehicle On-board Data (Pspec*)

This process shall be responsible for processing data received as input to sensors located on-board a vehicle and from communications with other surrounding vehicles. The process shall continuously analyze these inputs, along with a precise current location of the vehicle provided by the Location Data Source terminator. The traffic and environmental probe data may be sent to another process for roadside processing. The process may produce data from which safety, environmental, and/or position warnings and actions can be produced by another process. It shall also analyze the data to check for hazardous roadside conditions such as flooding, ice, snow, etc. and if detected shall output this data to processes in the Manage Traffic, Manage Maintenance and Construction, Manage Emergency Services, and Provide Driver and Traveler Services functions. This process shall communicate the status of the safety systems on-board to surrounding vehicles using wireless communications safety messages. For High Occupancy Vehicle lanes, this process shall determine the number of occupants on board from the Basic Vehicle inputs and provide it to the roadside for processing. This process shall calculate vehicle speed and distance traveled, and provide time-stamped data to another process as VMT data for calculation of vehicle road use charges.
