| 1.0 | TRAVEL AND TRAFFIC MANAGEMENT |
| 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. |
| 1.6.2 | TC shall include a Traffic Surveillance function. |
| 1.6.2.5 | The wide area surveillance shall acquire sufficient data to provide the system with the knowledge of the existing conditions. |
| 1.6.2.5.2 | The data process function shall process traffic data to generate near term predictions of traffic conditions. |
| 1.6.3 | TC shall include a Device Control function. |
| 1.6.3.5 | Device Control shall provide the operator with the capability to manually override the system's automatic controls. |
| 1.6.3.6 | Device Control shall provide the operator the capability to adaptively change system response in order to provide a response that is coordinated with other TMCs responding to incidents. |
| 1.6.4 | Device Control shall provide traffic control information to other elements of the ITS, including but not limited to the following: |
| 1.6.4(a) | In-vehicle navigation. |
| 5.0 | EMERGENCY MANAGEMENT |
| 5.3 | DISASTER RESPONSE AND EVACUATION |
| 5.3.0 | ITS shall provide a Disaster Response and Evacuation (DRE) function that provides for effective, coordinated management of the surface transportation system during all types of disasters including natural disasters (hurricanes, earthquakes, floods, severe winter storms, tsunamis, etc.), terrorist acts, and other catastrophic events (e.g., nuclear power plant disasters). Two primary subservices are provided: (1) Disaster Response and (2) Evacuation Coordination. The Disaster Response Subservice provides support for planning, transportation management, resource sharing, and information coordination between transportation agencies and principal responding agencies (emergency management, public safety, and other allied agencies) to improve the effectiveness and safety of a disaster response. The Disaster Response Subservice consists of eight major functions: 1) Coordinate Response Plans, 2) Monitor Alert Levels, 3) Detect and Verify Emergency, 4) Assess Infrastructure Status, 5) Coordinate Response, 6) Critical Service Restoration, 7) Manage Area Transportation, and 8) Disaster Traveler Information. The Evacuation Coordination (EC) Subservice efficiently manages an evacuation and provides evacuees with the information they need during evacuation and subsequent reentry to the evacuated area. The Evacuation Coordination (EC) subservice includes four additional major functions: 9) Evacuation Planning Support, 10) Evacuation Traveler Information, 11) Evacuation Transportation Management, and 12) Evacuation Resource Sharing. |
| 5.3.2 | Disaster Response shall provide a Monitor Alert Levels (MAL) function. |
| 5.3.2.2 | MAL shall increase system preparedness as the alert level or the likelihood of a disaster increases, taking actions including: |
| 5.3.2.2(g) | Implement traffic management strategies and traffic control plans |
| 5.3.5 | Disaster Response shall include a Manage Area Transportation (MAT) function that manages the transportation system in the vicinity of the disaster. Depending on the nature of the disaster and the status of the infrastructure, the following actions may be taken. |
| 5.3.5.4 | Special traffic control strategies to manage traffic in the vicinity of the disaster shall be implemented to limit and/or manage traffic in the area to include signal timing modifications and special traffic signal modes used in conjunction with personnel manually directing traffic. |
| 5.3.5.5 | Special traffic management strategies shall be implemented in surrounding areas to support efficient movement of personnel and resources into the disaster area. |
| 5.3.7 | Disaster Response shall include a Coordinate Response (CR) function to coordinate the disaster response between transportation, public safety, emergency management, and other allied agencies. Information may be shared with individual agency centers, emergency operations centers, and unified command systems at the scene. |
| 5.3.7.1 | CR shall provide information about the transportation system including: |
| 5.3.7.1(c) | Traffic management strategies in effect, including closures, detours, tolls, and HOV restrictions. |
| 5.3.11 | Evacuation Coordination shall provide an Evacuation Transportation Management (ETM) function to assist evacuation coordination personnel as they manage evacuation operations. |
| 5.3.11.3 | ETM shall include a strategy selection function that maximizes efficiency during evacuation and reentry operations and supports the overall response plan of the principal responding agencies. |
| 5.3.11.3.1 | The strategy shall integrate the control of freeways and surface streets. |
| 5.3.11.4 | ETM shall provide the control of devices as required by the evacuation management plan, including: |
| 5.3.11.4(a) | traffic signals, |
| 5.3.11.4(b) | dynamic message signs, |
| 5.3.11.4(c) | ramp meters, |
| 5.3.11.4(d) | reversible lane signs, |
| 5.3.11.4(e) | turning restriction signs, |
| 5.3.11.4(f) | road closure devices, |
| 5.3.11.4(g) | lane closure devices, |
| 5.3.11.4(h) | HAR, |
| 5.3.11.4(j) | shoulder use signs. |
| 5.3.11.12 | ETM shall implement special traffic control strategies including traffic diversions and closures if emergency termination of an in-process evacuation is required. |
| 7.0 | INFORMATION MANAGEMENT |
| 7.1 | ARCHIVED DATA FUNCTION |
| 7.1.0 | ITS shall provide an Archived Data Function to control the archiving and distribution of ITS data. The Archived Data User Service provides the Historical Data Archive Repositories and controls the archiving functionality for all ITS data with five major functions: 1) the Operational Data Control function to manage operations data integrity; 2) the Data Import and Verification function to acquire historical data from the Operational Data Control function; 3) the Automatic Data Historical Archive function for permanently archiving the data; 4) the Data Warehouse Distribution function, which integrates the planning, safety, operations, and research communities into ITS and processes data products for these communities; and 5) the ITS Community Interface which provides the ITS common interface to all ITS users for data products specification and retrieval. ADUS helps achieve the ITS information goal of unambiguous interchange and reuse of data and information throughout all functional areas. |
| 7.1.3 | The Archived Data Function shall include a Data Import and Verification (DIV) function to acquire historical data from the Operational Data Control function. |
| 7.1.3.1 | DIV shall be capable of importing selected ITS Operational data from the ITS Operational Repositories. |
| 7.1.3.1.9 | DIV shall be capable of importing data on ITS Physical Characteristics of Transportation Infrastructure to include: |
| 7.1.3.1.9(d) | Transportation facilities. |
