State DOT Field Equipment Equipment Packages

 

The following equipment packages are associated with the "State DOT Field Equipment" element.   Select the "Details" icon to see the detailed requirements associated with each equipment package, or consult the National ITS Architecture web site for more information.

 

Field Barrier System Control

Field elements that control barrier systems such as gates and other systems that manage entry to roadways, transportation facilities and infrastructure.

 

Roadway Basic Surveillance

Field elements that monitor traffic conditions using loop detectors and CCTV cameras.

 

Roadway Environmental Monitoring

Environmental sensors, surface and sub-surface, that collect weather and road surface information. Weather conditions measured include temperature, wind, humidity, precipitation, and visibility. Sensors measure road surface temperature, moisture, icing, salinity, etc.

 

Roadway Equipment Coordination

Field elements that control and send data to other field elements (such as environmental sensors that send data to a DMS or coordination between traffic controllers on adjacent intersections), without center control.

 

Roadway Probe Data Communications

Field elements that collect probe data from vehicles using short range communications.

 

Roadway Traffic Information Dissemination

Driver information systems, such as dynamic message signs and Highway Advisory Radio (HAR).

 

Roadway Traffic Metering

Control equipment including ramp, interchange, and mainline meters and the dynamic message signs that provide information about the meters and any special bypass lanes.

 

Roadway Work Zone Traffic Control

Field elements in maintenance and construction areas including CCTV cameras, driver information systems (such as DMS), and gates/barriers that monitor and control traffic and provide information directly to drivers in affected areas.
