TMC Traffic Network Performance Evaluation

Description

Measures performance and predicts travel demand patterns to support traffic flow optimization, demand management, and incident management. Collects data from surveillance equipment as well as input from other management centers including emissions, event promoters, and other TMCs.

Included In

North Texas Tollway Authority Traffic Management Center
Local Traffic Management Center

Functional Requirements

ID Requirement
1 The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center to support overall network performance evaluations.
2 The center shall collect wide-area pollution data from emissions management centers to support overall network performance evaluations.
3 The center shall collect and store plans from event promoters for major future events possibly impacting traffic to support overall network performance evaluations.
4 The center shall collect and store anticipated route information from information service providers to support overall network performance evaluations and predictions.
5 The center shall exchange information with transit management centers including details current transit routes, the level of service on each route, and the progress of individual vehicles along their routes for use in forecasting demand and estimating current transportation network performance.
6 The center shall exchange traffic information with other traffic management centers, including incidents, congestion data, traffic data, signal timing plans, and real-time signal control information to support overall network performance evaluations.
7 The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for network performance evaluations.
8 The center shall provide an interface to the archive data repository to enable the operator to retrieve historical operating data for use in planning to predict future traffic patterns and conditions.
9 This center shall use the collected information to measure overall current and forecast network performance and predict travel demand patterns.
