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.

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.
• The field element shall return sensor and CCTV system operational status to the controlling center.

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.

Roadway Speed Monitoring and Warning

• The field element shall include sensors to detect vehicle speeds, under traffic or maintenance center control.
• If the speed detected by vehicle speed sensors is determined to be excessive, the field element shall provide a safe speed advisory to passing drivers via a driver information system (such as portable messages signs, field to vehicle communications to in-vehicle signing systems, etc.).
• The field element shall return operational status for the vehicle speed sensors to the enforcement agency.
• The field element shall return fault data for the vehicle speed sensors to the controlling center for repair.

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 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 receive inputs concerning upcoming events that would effect the traffic network from event promoters and traveler information service providers.
• 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.
• The center shall coordinate planning for incidents with emergency management centers - including pre-planning activities for disaster response, evacuation, and recovery operations.
• The center shall share resources with allied agency centers to implement special traffic control measures, assist in clean up, verify an incident, etc. This may also involve coordination with maintenance centers.
• The center shall receive inputs concerning upcoming events that would effect the traffic network from event promoters, traveler information service providers, media, border crossings, and rail operations centers.
• The center shall provide road network conditions and traffic images to emergency management centers, maintenance and construction centers, and traveler information service providers.
• The center shall monitor incident response performance and calculate incident response and clearance times.
• The center shall exchange road network status assessment information with emergency management and maintenance centers including an assessment of damage sustained by the road network including location and extent of the damage, estimate of remaining capacity, required closures, alternate routes, necessary restrictions, and time frame for repair and recovery.
• The center shall coordinate information and controls with other traffic management centers.
• The center shall receive inputs from emergency management and transit management centers to develop an overall status of the transportation system including emergency transit schedules in effect and current status and condition of the transportation infrastructure.

TMC Signal Control

• The center shall remotely control traffic signal controllers.
• The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
• The center shall collect traffic signal controller fault data from the field.
• The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
• The center shall implement control plans to coordinate signalized intersections based on data from sensors.
• The center shall manage boundaries of the control sections used within the signal system.
• The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.

TMC Traffic Information Dissemination

• The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
