KC Scout Traffic Center - Traffic Management Functionality
Subsystem Description
The Traffic Management Subsystem (TMS) monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. This subsystem communicates with the Roadway Subsystem to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. This subsystem coordinates with the Maintenance and Construction Management Subsystem to maintain the road network and coordinate and adapt to maintenance activities, closures, and detours. Incidents are detected, verified, and incident information is provided to allied agencies, drivers (through Roadway Subsystem highway advisory radio and dynamic message signs), and information service providers. This subsystem also manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters. When required, special traffic management strategies are implemented to support evacuation and reentry. The Traffic Management Subsystem supports HOV lane management and coordination, road pricing, and other demand management policies that can alleviate congestion and influence mode selection. It also manages reversible lane facilities and barrier and safeguard systems that control access to transportation infrastructure. The subsystem communicates with other Traffic Management Subsystems to coordinate traffic information and control strategies in neighboring jurisdictions. It also coordinates with rail operations to support safer and more efficient highway traffic management at highway-rail intersections. Finally, the Traffic Management Subsystem provides the capabilities to exercise control over those devices utilized for automated highway system (AHS) traffic and vehicle control.
Functional Area: TMC Regional Traffic Management
Coordination between traffic management centers in order to share traffic information between centers as well as control of traffic management field equipment. This may be used during incidents and special events and during day-to-day operations.
| ID | Requirement | Status |
|---|---|---|
| 1 | 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. | Near-term |
| 2 | 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.). | Near-term |
Functional Area: TMC Traffic Information Dissemination
Controls dissemination of traffic-related data to other centers, the media, and travelers via the driver information systems (DMS, HAR) that it operates.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers. | Near-term |
| 3 | The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.). | Near-term |
| 4 | The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair. | Near-term |
Functional Area: TMC Transportation Operations Data Collection
Collects real-time information on the state of the regional transportation system for operational use by the center. It establishes communications with a regional repository, requests or subscribes to information relevant to the center, and distributes the received information for use.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall collect real-time information on the state of the regional transportation system including current traffic and road conditions, weather conditions, special event and incident information. | Medium-term |
| 2 | The center shall support the capability for the system operator to monitor and control the information collection service. | Medium-term |
Functional Area: TMC Work Zone Traffic Management
Coordination with maintenance systems using work zone images and traveler information systems (such as DMS), and distribution of work plans so that work zones are established that have minimum traffic impact.
| ID | Requirement | Status |
|---|---|---|
| 6 | The center shall receive proposed maintenance and construction work plans, analyze the activity as a possible incident, and provide work plan feedback to the sending center. | Medium-term |
Functional Area: Traffic Data Collection
Collection and storage of traffic management data. For use by operations personnel or data archives in the region.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall collect traffic management data such as operational data, event logs, etc. | Long-term |
| 2 | The center shall assign quality control metrics and meta-data to be stored along with the data. Meta-data may include attributes that describe the source and quality of the data and the conditions surrounding the collection of the data. | Long-term |
| 3 | The center shall receive and respond to requests from ITS Archives for either a catalog of the traffic data or for the data itself. | Long-term |
| 4 | The center shall be able to produce sample products of the data available. | Long-term |
