Regional ITS Architecture Dec2022-Update

Freeway Management for Dallas Regional ITS Architecture Roles and Responsibilities

Stakeholder	Role and Responsibility
LBJ Express	Operate reversible lanes including warning systems, barriers and lane strategies.
	Operate and maintain field equipment that controls and sends data to other field equipment (such as environmental sensors that send data to a DMS or coordination between traffic controllers on adjacent intersections), without being controlled from a center.
	Monitor traffic conditions using field equipment (i.e. loop detectors and CCTV cameras).
	Monitor and remotely diagnose field equipment issues including detecting failures, issuing problem reports, and tracking the repair or replacement of failed equipment.
	Distribute current traffic conditions to other centers.
	Disseminate traffic–related data to other centers, the media, and travelers via the driver information systems (DMS, HAR).
	Control traffic signal controllers remotely to implement traffic management strategies at signalized intersections based on traffic conditions, incidents, emergency vehicle preemptions, pedestrian crossings, etc.
	Collect current traffic conditions from sensors and surveillance equipment.
	Monitor air quality and emissions.
North Texas Tollway Authority	Disseminate traffic–related data to other centers, the media, and travelers via the driver information systems (DMS, HAR).
	Control traffic signal controllers remotely to implement traffic management strategies at signalized intersections based on traffic conditions, incidents, emergency vehicle preemptions, pedestrian crossings, etc.
	Distribute current traffic conditions to other centers.
	Distribute current traffic conditions to other centers.
