WCDPWT Communications Infrastructure

Status: Existing

Description

WCPDWT communications infrastructure includes Copper Cable, Fiber Optic Cable, and Wireless technologies. Copper Cable is part of the county's ITS communications infrastructure primarily servicing the county's traffic signal systems. WCDPWT Fiber Optic Cable supports local CCTV. WCDPWT Wireless systems provide communications for traffic detection devices in the county (e.g. Adaptive Traffic Signal System).

Functional Objects

Functional ObjectDescriptionUser Defined
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 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

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.
