6.2.2: Collect Traffic Data
This process shall collect traffic, reversible/hov lane restriction data, toll, vehicle probe, commercial vehicle restrictions and permitting data as well as maintenance and construction data to be used for traveler information, trip planning, route guidance, and ridesharing applications and sent to the media. Data quality checks shall be performed on all collected data. Upon receipt of traveler information alert subscriptions, this process shall output relevant traffic alerts. This process shall exchange information with Other Transportation Information Centers (TIC) to allow one TIC to act as a wholesaler and provide information to other TICs. This process shall use the parameters in the data store of 'traffic data retrieval parameters' to define exactly what data shall be retrieved as a result of each request. The process shall select the appropriate subset of data which will be sent to each ITS application or entity that is requesting data. The process shall provide all of the received information to the TIC Operator Interface process and receive the data collection parameters from the operator interface process.
This process is associated with the Transportation Information Center physical object.
This process is associated with the following functional objects:
- TIC Data Collection
- TIC Road Weather Advisories and Warnings
- TIC Situation Data Management
