The following equipment packages are associated with the "City of Sherman ITS 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 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.
Field elements that provide video images of traffic conditions, including advanced CCTV cameras with built-in incident detection algorithms.
Field elements to collect traffic and road conditions from passing vehicles; both anonymous toll/parking tag readings for link time calculations and smart probe data supported.
Field elements including traffic signal controllers for use at major intersections and on main highways for urban areas; also supports pedestrian crossings.
Field elements that provide the capability to receive vehicle signal priority requests and control traffic signals accordingly.
Roadway Traffic Information Dissemination
Driver information systems, such as dynamic message signs and Highway Advisory Radio (HAR).
Work zone intrusion detection devices (to detect vehicle intrusion upon a work zone or crew worker movement across a work zone boundary) and intrusion alerting devices that provide alerts to crew and drivers.
Roadway Work Zone Traffic Control
Field elements in a work zone that manage traffic conditions using CCTV cameras and driver information systems (such as DMS) to provide information directly to drivers affected by the work zone activity.
Field elements 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). Includes traditional HRI warning systems augmented with other standard traffic management devices.
