6.2.3: Collect Transit Operations Data

This process shall collect and fuse transit services data that will be used to create broadcast or interactive messages to travelers and other operations centers as well as support trip planning and route guidance applications. Data quality checks shall be performed on all collected data. Upon receipt of traveler information alert subscriptions, this process shall output relevant transit alerts. This process shall collect transit service information including schedules, fares, deviations, incidents, and transfer points. The process shall load the incoming data into the 'transit_traveler_data' store. The data can be provided to the process either via direct request from the process or as a result of periodic (unrequested) updates. This process shall provide the media with transit information. This process shall exchange information with Other Information Service Providers to allow one ISP to act as a wholesaler and provide information to other ISPs. 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 ISP Operator Interface process and receive the data collection parameters (to define exactly what data shall be retrieved as a result of each request) from the operator interface process.

This process is associated with the Transportation Information Center physical object.
