National ITS Architecture Functional Requirements
associated with Sedgwick County Roadside Equipment:

1. The field element shall control traffic signals at intersections and on main highways for urban and rural areas, under center control.
2. The field element shall collect pedestrian images and pedestrian sensor data, and respond to pedestrian crossing requests via display, audio signal, or other manner.
3. The field element shall monitor operation of traffic signal controllers and report to the center any instances in which the indicator response does not match that expected from the indicator control information.
4. The field element shall monitor operation of traffic signal controllers and report to the center any instances in which the indicator response does not match that expected from known indicator preemptions.
5. The field element shall return traffic signal controller operational status to the controlling center.
6. The field element shall return traffic signal controller fault data to the maintenance center for repair.

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's video devices shall be remotely controlled by a traffic management center.
2. 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 collect and process, traffic sensor data in the vicinity of a highway-rail intersection (HRI).
2. The field element shall monitor the status of the highway-rail intersection (HRI) equipment, including both the current state and mode of operation and the current equipment condition, to be forwarded on to the traffic management center.
3. The field element shall monitor the status of the highway-rail intersection (HRI) equipment, including both the current state and mode of operation and the current equipment condition, to be forwarded on to the rail wayside equipment.
4. The field element shall receive track status from the rail wayside equipment that can be passed on to the traffic management center. This may include the current status of the tracks and whether a train is approaching.
5. The field element shall control the dynamic message signs (DMS) in the vicinity of a highway-rail intersection (HRI) to advise drivers, cyclists, and pedestrians of approaching trains.
6. The field element shall support the integrated control of adjacent traffic signals to clear an area in advance of an approaching train and to manage traffic around the intersection.
7. The field element shall forward rail traffic advisories received from the Wayside Equipment to the traffic management center.
