Suburban Community Field Equipment

Status: Existing

Description

Generic element representing local cities' ITS roadside field equipment not specifically enumerated in other inventory elements. This suggests that these traffic signal systems that are widely scattered throughout the WAMPO area should be integrated in a consistent fashion, when circumstances require. ITS field equipment may include traffic signals, vehicle detectors, CCTV cameras, dynamic message signs, etc., to control and monitor traffic.

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.
