This element represents dynamic message signs owned by the Westchester County Police Department, these signs are owned and operated by the department and are not connected to HVTMC. The department does not currently have CCTV systems for monitoring roadways but they do have other detectors like license plate readers. CCTV equipment is planned for installation along peripheral roads in collaboration with New York State.
| Functional Object | Description | User Defined |
| Roadway Basic Surveillance | 'Roadway Basic Surveillance' monitors traffic conditions using fixed equipment such as loop detectors and CCTV cameras. | 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 Signal Monitoring and Enforcement | 'Roadway Signal Monitoring and Enforcement' includes the field elements that monitor vehicles entering a signalized intersection. Information is collected for vehicles illegally entering the intersection, and the signal violation is reported to the enforcement center. Control and monitoring of the signal monitoring and enforcement equipment is provided with an interface to the Traffic Management Center. | False |
| Roadway Speed Monitoring and Warning | 'Roadway Speed Monitoring and Warning' includes the field elements that monitor vehicle speeds. If the speed is determined to be excessive, an advisory or warning is displayed. Current environmental conditions and other factors that may reduce safe operating speeds may also be taken into account. The operational status (state of the device, configuration, and fault data) is provided to the center. This application can also provide an enforcement function, reporting speed violations to an enforcement agency. | 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 |
| Document Number | Title | Description |
| 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. |
