Project Inventory:

Collect Traffic Surveillance

• The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
• The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.

Incident Command

• The center shall provide tactical decision support, resource coordination, and communications integration for Incident Commands that are established by first responders to support local management of an incident.
• The center shall provide incident command communications with public safety, emergency management, transportation, and other allied response agency centers.

Roadway Basic Surveillance

• The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.
• The field element shall collect, process, and send traffic images to the center for further analysis and distribution.

Roadway Equipment Coordination

• The field element shall include sensors that provide data and status information to other field element devices, without center control.

Roadway HOV Control

• The field element shall include freeway control devices that control use of lanes, under center control.

Roadway Probe Beacons

• The field element shall communicate with passing vehicles for traffic data link time calculations and send collected data to the controlling center; identification will be removed to ensure anonymity.

Roadway Signal Controls

• The field element shall control traffic signals under center control.
• The field element shall report the current signal control information to the center.
• The field element shall return traffic signal controller operational status to the center.
• The field element shall return traffic signal controller fault data to the center.

Roadway Traffic Information Dissemination

• The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).

TMC HOV Lane Management

• The center shall remotely control freeway control devices that control use of lanes.

TMC Incident Detection

• The center shall collect and store traffic flow and image data from the field equipment to detect and verify incidents.
• The center shall exchange incident and threat information with emergency management centers as well as maintenance and construction centers; including notification of existence of incident and expected severity, location, time and nature of incident.

TMC Incident Dispatch Coordination/Communication

• The center shall exchange alert information and status with emergency management centers. The information includes notification of a major emergency such as a natural or man-made disaster, civil emergency, or child abduction for distribution to the public. The information may include the alert originator, the nature of the emergency, the geographic area affected by the emergency, the effective time period, and information and instructions necessary for the public to respond to the alert. This may also identify specific information that should not be released to the public.

TMC Probe Information Collection

• The center shall collect traffic probe data from vehicles via roadside field equipment.

TMC Regional Traffic Control

• The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
• The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).

TMC Traffic Information Dissemination

• The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
