Functional Objects

Functional ObjectDescriptionUser Defined
Roadway Emissions Monitoring'Roadway Emissions Monitoring' monitors emissions and general air quality and communicates the collected information back to the Emissions Management Center where it can be monitored, analyzed, and used. This functional object supports point monitoring of individual vehicle emissions as well as general monitoring of standard air quality measures.False
Roadway Reversible Lanes'Roadway Reversible Lanes' includes field elements that monitor and control reversible lane facilities. It includes the traffic sensors, surveillance equipment, lane control signals, physical lane access controls, and other field elements that manage traffic on these facilities. It provides current reversible lane facility status information and accepts requests and control commands from the controlling center.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.
USDOT RSUDedicated Short–Range Communications Roadside Unit Specifications (FHWA–JPO–17–589)This document will specify the requirements for roadside units (RSU) to serve as a network edge device for 5.9GHz DSRC infrastructure.
