1.2.2.1: Determine Indicator State for Freeway Management

This process shall implement selected traffic control strategies and transit vehicle overall priority on some or all of the indicators covering the freeway network served by the Manage Traffic function. It shall implement the traffic control strategies only using the indicators (e.g., reversible lane signals) specified in the implementation request and shall coordinate its actions with those of the process that controls the road network. The process shall also be capable of monitoring the extra inputs that will arise where tunnels are involved, including the detection of fire and the consequent requirement to re-route traffic.

This process is associated with the Traffic Management Center physical object.

This process is associated with the following functional objects:

• TMC Dynamic Lane Management and Shoulder Use
• TMC Multi-Modal Coordination
• TMC Restricted Lanes CV Application
• TMC Traffic Metering
