1.1.6: Collect Vehicle Traffic Surveillance Data

This process shall collect traffic data from passing vehicles that are equipped with a tag or a short range communications device. This could be as simple as reading a toll tag from which the link time may be calculated, or could involve communications with equipment onboard the vehicle that provides the vehicle's average speed, road conditions, and other information that may be used to determine traffic conditions. The field equipment represented by this process collects the information and sends it to a center for processing and distribution. The process may also send the information to the Map Update System. In all of these roadside systems, the tag or vehicle ID is read and translated into a unique but anonymous ID that is not traceable in any way to the tag or vehicle owner. The process shall return operational status (state of the device, configuration, and fault data) of the vehicle equipment to another process for repair. The process shall provide traffic data to the archival process.
