1.1.1.5: Provide Sensor Interface to Other Roadway Devices

This process shall provide the interface between roadway sensors and other roadway devices (considered to be contained in the Other ITS Roadway Equipment terminator) for the exchange of data, status, and control. The other roadway devices can be adjacent geographically, under control of a different jurisdiction, or part of a more complex hierarchy. The data input to this process shall include sensor data from the sensors such as the following- traffic, environmental, and work zone intrusion detection. Additionally status and fault indications from the sensors shall be input to the process and passed along to the Other ITS Roadway Equipment terminator. Control data shall come from the Other ITS Roadway Equipment terminator into the process that shall output the control information to the correct sensor process. This process supports the collection of data locally on surface streets or freeways that might be needed to update nearby dynamic message signs with, for example, messages regarding road conditions or individual vehicle speed. This process and its companion process, Provide Device Interface to Other Roadway Devices, support autonomous traffic information dissemination without the need for direct control from a Manage Traffic function.

This process is associated with the ITS Roadway Equipment physical object.
