Functional Objects

Functional ObjectDescriptionUser Defined
Roadway Field Device Support'Roadway Field Device Support' monitors the operational status of field devices and detects and reports fault conditions. Consolidated operational status (device status, configuration, and fault information) are reported for resolution and repair. A local interface is provided to field personnel for local monitoring and diagnostics, supporting field maintenance, upgrade, repair, and replacement of field devices.False
Roadway Field Management Station Operation'Roadway Field Management Station Operation' supports direct communications between field management stations and the local field equipment under their control.False
Roadway Mixed Use Crossing Safety'Roadway Mixed Use Crossing Safety' is an advanced infrastructure application that detects pedestrians, cyclists, and other non–motorized users and provides active safety warnings to drivers when cross walks or other intersecting mixed use paths are occupied.False
Roadway Signal Control'Roadway Signal Control' includes the field elements that monitor and control signalized intersections. It includes the traffic signal controllers, detectors, conflict monitors, signal heads, and other ancillary equipment that supports traffic signal control. It also includes field masters, and equipment that supports communications with a central monitoring and/or control system, as applicable. The communications link supports upload and download of signal timings and other parameters and reporting of current intersection status. It represents the field equipment used in all levels of traffic signal control from basic actuated systems that operate on fixed timing plans through adaptive systems. It also supports all signalized intersection configurations, including those that accommodate pedestrians. In advanced, future implementations, environmental data may be monitored and used to support dilemma zone processing and other aspects of signal control that are sensitive to local environmental conditions.False
Roadway Signal Preemption'Roadway Signal Preemption' includes the field elements that receive signal preemption requests from emergency vehicles approaching a signalized intersection and overrides the current operation of the traffic signals to stop conflicting traffic and grant right–of–way to the approaching vehicle.False

Physical Standards

Document NumberTitleDescription
ITE ATC 5201Advanced Transportation ControllerThis standard defines the functionality and performance requirements for a modern ITS controller known as an ATC. It is similar to the NEMA TS–2 standard in that it defines basic capabilities but leaves hardware choices up to the manufacturer.
ITE ATC 5202Model 2070 Controller StandardThis standard specifies the hardware for a modern, open–architecture controller for ITS applications that can run Linux and is capable of executing advanced signal controller logic, among other things.
ITE ATC 5301Intelligent Transportation System Standard Specification for Roadside CabinetsThis standard specifies the characteristics of a modern controller cabinet for the ITS industry.
ITE ATC 5401Application Programming Interface Standard for the Advanced Transportation ControllerThis standard defines the application programmers' interface (API) that should be supported by an ATC, which is an open–architecture controller that can host multiple ITS applications.
NEMA TS 8Cyber and Physical Security for Intelligent Transportation SystemsThis specification describes how agencies and other transportation infrastructure owner/operators should implement cyber– and physical–security for ITS.
NEMA TS2Traffic Controller Assemblies with NTCIP RequirementsThis specification covers traffic signaling equipment used to facilitate and expedite the safe movement of pedestrians and vehicular traffic.
