City of Lubbock Field Equipment Equipment Packages

 

The following equipment packages are associated with the "City of Lubbock Field Equipment" element.   Select the "Details" icon to see the detailed process specifications that support each equipment package, or consult the National ITS Architecture web site for more information.

 

Roadside Signal Priority

This Equipment package shall provide the capability to receive vehicle signal priority requests and control roadside signals accordingly.

 

Roadway Basic Surveillance

This Equipment package provides the capabilities to monitor traffic flow in major intersections and on main highways for urban areas and to monitor road conditions using fixed equipment such as loop detectors and wireline communication.

 

Roadway Equipment Coordination

This equipment package coordinates field equipment that is distributed along the roadway by supporting communications directly between the field equipment. This includes coordination between remote sensors and field devices (e.g., Dynamic Message Signs) and coordination between the field devices themselves (e.g., coordination between traffic controllers that are controlling adjacent intersections.).

 

Roadway Incident Detection

This Equipment package provides incident detection capability to reside at the roadside. For example, advanced CCTV's with built-in incident detection algorithms would allow the actual detection function to be roadside rather than transmitting images to a center for visual or automated detection.

 

Roadway Signal Controls

This Equipment package provides the capabilities to control traffic signals at major intersections and on main highways for urban areas. This Equipment package is generally constrained to a single jurisdiction.

 

Roadway Speed Monitoring

This equipment package monitors vehicle speeds. If the speed is determine to be excessive, then roadside equipment can suggest a safe driving speed. Environmental conditions may be monitored and factored into the safe speed advisories that are provided to the motorist. This equipment package can also provide an enforcement function, reporting speed violations to an enforcement agency.

 

Roadway Traffic Information Dissemination

This Equipment package provides the roadside elements of traffic information dissemination including DMS, HAR, and talking pedestrian signs.

 

Roadway Work Zone Safety

This equipment package detects vehicle intrusions in work zones and warns crew workers and drivers of imminent encroachment. Crew movements are also monitored so that the crew can be warned of movement beyond the designated safe zone.

 

Roadway Work Zone Traffic Control

This equipment package directs activity in work zones, controlling traffic through portable dynamic message signs (DMS) and informing other groups of activity (e.g., ISP, TM, other maintenance and construction centers) for better coordination management. Work zone speeds and delays are provided to the motorist prior to the work zones

 

Standard Rail Crossing

This Equipment Package manages highway traffic at highway-rail intersections (HRIs) where operational requirements do not dictate advanced features (e.g., where rail operational speeds are less than 80 miles per hour). Either passive (e.g., the crossbuck sign) or active warning systems (e.g., flashing lights and gates) are supported depending on the specific requirements for each intersection. These traditional HRI warning systems may also be augmented with other standard traffic management devices. The warning systems are activated on notification by interfaced wayside equipment of an approaching train. The equipment at the HRI may also be interconnected with adjacent signalized intersections so that local control can be adapted to highway-rail intersection activities. Health monitoring of the HRI equipment and interfaces is performed; detected abnormalities are reported through interfaces to the wayside interface equipment and the traffic management subsystem.
