National ITS Architecture Functional Requirements
associated with KDOT TOC (Wichita Metro) Roadside Equipment:

1. The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
2. The field element shall return sensor and CCTV system operational status to the controlling center.
3. The field element shall return sensor and CCTV system fault data to the controlling center for repair.

1. The field element shall include ramp metering controllers, mainline meters, and lane controls for use on freeways, under center control.
2. The field element shall monitor operation of ramp meter, mainline meters, and lane control indicators and report to the center any instances in which the indicator response does not match that expected from the indicator control information.
3. The field element shall monitor operation of ramp meter, mainline meters, and lane control indicators and report to the center any instances in which the indicator response does not match that expected from known indicator preemptions.
4. The field element shall return ramp metering controller, mainline meters, and lane control operational status to the controlling center.
5. The field element shall return ramp metering controller, mainline meters, and lane control fault data to the maintenance center for repair.
6. The field element shall provide indications to the driver that a freeway ramp or a lane is available for use, with possible usage data for the freeway lanes they are entering.

1. The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
2. The field element shall include driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers, under center control.
3. The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
4. The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.

1. The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
2. The field element shall remotely process video data and provide an indication of potential incidents to the traffic management center.
3. The field element's video devices shall be remotely controlled by a traffic management center.
4. The field element shall provide operational status and fault data for the incident detection devices to the traffic management center.

1. The field element shall include devices (such as arterial or freeway controllers, roadway automated treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems) that provide data and status information to other field element devices (such as dynamic message signs, traffic controllers on adjacent intersections), without center control.
2. The field element shall include devices (such as arterial or freeway controllers, roadway automated treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems) that receive control information from other field element devices, without center control.

1. The field element shall include surface and sub-surface environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
2. The field element shall include environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
3. The field element's environmental sensors shall be remotely controlled by a maintenance center.
4. The field element's environmental sensors shall be remotely controlled by a traffic management center.
5. The field element shall provide environmental sensor equipment operational status to the controlling center or maintenance vehicle.
6. The field element shall provide environmental sensor equipment fault indication to the controlling center or maintenance vehicle.
7. The field element shall remotely aggregate environmental sensor data with environmental data collected from maintenance and construction vehicles.
8. The field element shall provide weather and road surface condition data to centers.
9. The field element shall provide weather and road surface condition data to maintenance and construction vehicles.

1. The field element shall collect traffic, road, and environmental conditions information.
2. The field element shall include the sensors and supporting roadside devices that sense, collect, and send traffic, road, and environmental conditions information to a center for archival.
3. The field element shall collect sensor status and sensor faults from roadside equipment and send it along with the recorded data to a center for archival.
