1.2.6.1: Maintain Traffic and Sensor Static Data

This process shall maintain the store of static and link data (including static parking data) used by other processes within the Manage Traffic function. The process shall also maintain the store of signal timing plans. From the data sent to this process by the Traffic Operations Personnel, the process creates the link data that is placed in the data store of static data for traffic control. Link data shall then be sent to the Provide Driver and Traveler Services function to enable it to obtain data about links that are not in the geographic area which it serves.

This process is associated with the following functional objects:

• TMC Basic Surveillance
• TMC Demand Management Coordination
• TMC Regional Traffic Management
