| 1.6.1.1.2 | Traffic-movement control shall manage movement of traffic on highways. |
| 1.6.1.1.3 | Traffic-movement control shall include the goal of minimizing delay times. |
| 1.6.1.1.4 | Traffic-movement control shall include the goal of minimizing energy use. |
| 1.6.1.1.5 | Traffic-movement control shall include the goal of minimizing air quality impacts due to traffic. |
| 1.6.1.2 | Traffic Flow Optimization shall include a wide area optimization capability, to include several jurisdictions. |
| 1.6.1.2.1 | Wide area optimization shall integrate the control of network signal systems with the control of freeways. |
| 1.6.1.2.2 | Wide area optimization shall include features that provide preferential treatment for transit vehicles. |
| 1.6.1.2.3 | Wide area optimization shall include features that provide preferential treatment for HOV. |
| 1.6.1.3 | Traffic Flow Optimization shall be implemented in a manner that seeks to optimize traffic movement over a large geographic area. |
| 1.6.1.4 | Traffic Flow Optimization shall include a Control function that is responsive to both the current demand as well as the expected demand. |
| 1.6.1.4.1 | The Control function shall include the capability to facilitate the dissipation of traffic congestion. |
| 1.6.1.5 | Traffic Flow Optimization shall provide the capability to predict travel patterns. |
| 1.6.1.6 | The Control function shall include the use of data acquired from traffic surveillance as feedback to the control strategies. |
| 1.6.1.7 | Implementation of the Control function shall include strategies that account for at least the following: |
| 1.6.1.7(a) | Human factors. |
| 1.6.1.7(b) | Driver/traveler behavior and expectancies. |
| 1.6.2 | TC shall include a Traffic Surveillance function. |
| 1.6.3 | TC shall include a Device Control function. |
| 1.6.3.1 | The Device Control function shall include a "real-time" traffic-adaptive control capability. |
| 1.6.3.2 | The real-time traffic-adaptive control portion of the Device Control function shall be an area wide control to include several jurisdictions. |
| 1.6.3.2.1 | The area wide control shall be implemented in an integrated and consistent manner that avoids the issuance of conflicting controls. |
| 1.6.3.2.2(a) | Transit. |
| 1.6.3.3 | The Device Control function shall provide the capability to exercise control over those devices utilized for traffic control. |
| 1.6.3.3.1 | Device Control shall include the capability to control traffic signalization, including rapid modification of signalization parameters to respond to traffic requirements. |
| 1.6.3.3.2 | Device Control shall include the capability to dynamically control traffic signing. |
| 1.6.3.3.3 | Device Control shall include the capability to control freeway ramp metering. |
| 1.6.3.3.4 | Device Control shall include the capability to exercise dynamic control over the infrastructure (such as reversible-lanes, turning restrictions, etc.). |
| 1.6.3.4 | Device Control shall communicate control data to the following devices. |
| 1.6.3.4(e) | Human operator support. |
| 1.6.3.4.1 | Traffic Surveillance shall include a data process function to process the traffic data which are acquired. |
| 5.0 | EMERGENCY MANAGEMENT |
| 5.2 | EMERGENCY VEHICLE MANAGEMENT |
| 5.2.3 | EVM Service shall include a Signal Priority System. |
| 5.2.3.1 | Signal Priority System shall maintain real-time information on signal timing, emergency vehicle locations and emergency vehicle routing. |
| 5.2.3.2 | Signal Priority System shall determine signal prioritize timing sequences for relevant signals. |
