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 Environmental Monitoring

This Equipment package measures environmental conditions and communicates the collected information back to a center where it can be monitored and analyzed. A broad array of general weather and road surface information may be collected. Weather conditions that may be measured include temperature, wind, humidity, precipitation, and visibility. Surface and sub-surface sensors can measure road surface temperature, moisture, icing, salinity, and other measures. Air quality monitoring can include point monitoring of individual vehicles as well as general monitoring of standard air quality measures.

 

Roadway Freeway Control

Ramp meters, CMS and other freeway control effects which will control traffic on freeways.

 

Roadway Probe Beacons

This Equipment package monitors traffic and road conditions by collecting information from passing vehicles that are equipped with a transponder or other short range communications device. The probe data collected by this equipment package may include link travel times, average speeds, road conditions, and any other data that can be measured and communicated by passing vehicles. This equipment package consists of roadside equipment that communicates with passing vehicles using dedicated short range communications, collects the information provided by the vehicles, and forwards this information back to the Traffic Management Subsystem.

 

Roadway Reversible Lanes

This Equipment package provides the capability for control of reversible lanes using sensor and actuator type equipment. This Equipment package also provides the capability to notify users the direction of the reversible lanes using electronic lane signs.

 

Roadway Traffic Information Dissemination

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