| 1.0 | TRAVEL AND TRAFFIC MANAGEMENT |
| 1.5.2 | TSI shall include an Information Access function that allows travelers to access the available information. |
| 1.5.2.5 | Information Access shall provide the capability for travelers to access the TSI information via any of, but not limited to, the following methods: |
| 1.5.2.5(a) | Highway advisory radio. |
| 1.6 | TRAFFIC CONTROL |
| 1.6.0 | ITS shall include a Traffic Control (TC) function. Traffic Control provides the capability to efficiently manage the movement of traffic on streets and highways. Four functions are provided, which are, (1) Traffic Flow Optimization, (2) Traffic Surveillance, (3) Control, and (4) Provide Information. This will also include control of network signal systems with eventual integration of freeway control. |
| 1.6.1.2.1 | Wide area optimization shall integrate the control of network signal systems with the control of freeways. |
| 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. |
| 1.6.2 | TC shall include a Traffic Surveillance function. |
| 1.6.2.4 | TC shall provide the capability to acquire detailed traffic measurements at specific locations. |
| 1.6.2.4.1 | Traffic Surveillance shall include a data process function to process the traffic data which are acquired. |
| 1.6.3 | TC shall include a Device Control function. |
| 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. |
| 1.6.3.2.2 | The area wide control shall be implemented in a manner that permits the following types of vehicles to have preference over other vehicles being controlled. |
| 1.6.3.2.2(b) | HOV. |
| 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. |
| 1.6.3.4.1 | Traffic Surveillance shall include a data process function to process the traffic data which are acquired. |
| 1.7 | INCIDENT MANAGEMENT |
| 1.7.0 | ITS shall include an Incident Management (IM) function. Incident Management will identify incidents, formulate response actions, and support initiation and ongoing coordination of those response actions. Four major functions are provided, which are, (1) Incidents Identification, (2) Response Formulation, (3) Response Implementation, and (4) Predict Hazardous Conditions. |
| 1.7.1 | Incident Management shall provide an Incident Identification function to identify incidents. |
| 1.7.1.1 | The Incident Identification function shall include the capability to identify predicted incidents. |
| 1.7.1.1.1 | The Incident Identification function shall use information from the following types of sources, where available, to identify predicted incidents: |
| 1.7.1.1.1(a) | Traffic flow sensors. |
| 1.7.2 | IM shall provide a Response Formulation function to formulate appropriate response actions to each identified incident and revise those actions when necessary. |
| 1.7.2.1 | The Response Formulation function shall propose and facilitate the appropriate scheduling of those predicted incidents that can be scheduled to minimize incident potential, incident impacts, and/or the resources required for incident management. |
| 1.7.3 | IM shall include a Response Implementation function to provide the services to implement a response coordinated with all appropriate agencies. |
| 1.7.3.2 | The Response Implementation function shall provide a link between Incident Management and all other user services necessary to implement incident response actions. |
| 1.7.4 | IM shall provide the capability to Predict Hazardous Conditions, including the time and location of hazardous conditions that may cause an incident. |
