Functional Objects
| Functional Object | Description | User Defined |
|---|
| Field System Executive | 'Field System Executive' includes the operating system kernel and executive functions that manage the overall device software configuration and operation and support configuration management, computer resource management, and govern software installation and upgrade. | False |
|---|
| Field System Monitoring and Diagnostics | 'Field System Monitoring and Diagnostics' includes background self–tests, diagnostics, watchdog timers, and other hardware and software that monitors the operating condition of field equipment. The status of the equipment and diagnostic information is provided to local maintenance personnel and the operating center. | False |
|---|
| Roadway Barrier System Control | 'Roadway Barrier System Control' includes the field equipment that controls barrier systems used to control access to transportation facilities and infrastructure. Barrier systems include automatic or remotely controlled gates, barriers and other access control systems. | False |
|---|
| Roadway Basic Surveillance | 'Roadway Basic Surveillance' monitors traffic conditions using fixed equipment such as loop detectors and CCTV cameras. | False |
|---|
| Roadway Incident Detection | 'Roadway Incident Detection' provides incident detection using traffic detectors and surveillance equipment. It monitors for unusual traffic conditions that may indicate an incident or processes surveillance images, watching for potential incidents. It provides potential incident information as well as traffic flow and images to the center for processing and presentation to traffic operations personnel. | False |
|---|
| Roadway Passive Monitoring | 'Roadway Passive Monitoring' monitors passing vehicles for a signature that can be used to recognize the same vehicle at different points in the network and measure travel times. Depending on the implementation and the penetration rate of the technology that is monitored, other point traffic measures may also be inferred by monitoring the number of vehicles within range over time. Today this approach is implemented most commonly using a Bluetooth receiver that passively monitors Bluetooth devices on–board passing vehicles and license plate readers that record the vehicle license plate number, but any widely deployed vehicle communications technology or feature that can be passively monitored to uniquely identify a vehicle could be used. | False |
|---|
| Roadway Safeguard System Control | 'Roadway Safeguard System Control' includes field equipment that controls safeguard systems for transportation facilities and infrastructure. Safeguard systems include blast shields, exhaust systems and other automatic or remotely controlled systems intended to mitigate the impact of an incident. | False |
|---|
| Roadway Traffic Information Dissemination | 'Roadway Traffic Information Dissemination' includes field elements that provide information to drivers, including dynamic message signs and highway advisory radios. | False |
|---|
| RSE Border Management | 'RSE Border Management' supports border operations, providing functions that measure border wait times and provide wait times and other traveler information to approaching vehicles. Short range communications with vehicles and associated equipment supports collection of traveler, vehicle, and cargo information and credentials. | False |
|---|
| RSE Road Closure Management | 'RSE Road Closure Management' communicates with qualified Connected Vehicles and barrier control systems to support local road closure management. It validates and requests implementation of road closure requests. During a closure, it can also support selective access to the closed area, only granting entry permission to allowed vehicles. | False |
|---|
| RSE Traveler Information Communications | 'RSE Traveler Information Communications' includes field elements that distribute information to vehicles for in–vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the short range communications equipment that provides information to passing vehicles. | False |

Physical Standards
| Document Number | Title | Description |
|---|
| CTI 4001 | Roadside Unit (RSU) Standard | This document establishes a non–proprietary, communications–agnostic, industry consensus Roadside Unit (RSU) Standard. An RSU is a transportation infrastructure communications device that is a part of a Cooperative Intelligent Transportation Systems (C–ITS) transportation environment. The goal of such an environment is to reduce the number of fatalities and injuries on roadways, improve mobility, and reduce environmental impacts of transportation systems. Commonly known as the Connected Vehicle (CV) environment in the United States (US), it includes both connected human–driven vehicles and connected automated vehicles (CAVs). The terms Vehicle–to–Infrastructure (V2I) and Vehicle–to–Vehicle (V2V) are used to reflect the exchanges of messages within the CV environment. The vision for this technology has expanded to include all types of travelers including pedestrians, cyclists, multimodal travelers, and other vulnerable road users (VRUs), and is referred to as Vehicle–to–Everything (V2X) technology and V2X communications. |

| ITE ATC 5201 | Advanced Transportation Controller | This 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 5202 | Model 2070 Controller Standard | This 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 5301 | Intelligent Transportation System Standard Specification for Roadside Cabinets | This standard specifies the characteristics of a modern controller cabinet for the ITS industry. |
|---|
| ITE ATC 5401 | Application Programming Interface Standard for the Advanced Transportation Controller | This 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 8 | Cyber and Physical Security for Intelligent Transportation Systems | This specification describes how agencies and other transportation infrastructure owner/operators should implement cyber– and physical–security for ITS. |
|---|
| NEMA TS2 | Traffic Controller Assemblies with NTCIP Requirements | This specification covers traffic signaling equipment used to facilitate and expedite the safe movement of pedestrians and vehicular traffic. |
|---|
| NEMA TS4 | Hardware Standards for Dynamic Message Signs (DMS) With NTCIP Requirements | This standard provides hardware specifications for safe, dependable, functional, and easily maintained Dynamic Message Sign (DMS) equipment. |
