ADOT Wrong Way Driver Detection System

Status: Existing

Description

ADOT owns and operates the ADOT Wrong Way Driver Detection System. When thermal cameras in the field are tripped by a wrong way driver (WWD), an alert is issued to the ADOT TOC operators. Once a WWD is verified by a TOC operator, the TOC operator activates a Decision Support System (DSS) that automatically changes the relevant DMS signs to warn other drivers and moves CCTV cameras to attempt to follow the WWD.

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.
NEMA TS4Hardware Standards for Dynamic Message Signs (DMS) With NTCIP RequirementsThis standard provides hardware specifications for safe, dependable, functional, and easily maintained Dynamic Message Sign (DMS) equipment.
