ITS Roadway Equipment --> Emissions Management Center:
air quality sensor data

Definitions

air quality sensor data (Information Flow): Measured air quality data, including measured levels of atmospheric pollutants including ozone, particulate matter, carbon monoxide, and nitrogen oxides, and operational status of the sensors.

ITS Roadway Equipment (Source Physical Object): 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway itself. In CVRIA, this physical object represents all of the other ITS field equipment that interfaces with and supports the Connected Vehicle Roadside Equipment (RSE). This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.

Emissions Management Center (Destination Physical Object): The 'Emissions Management Center' provides the capabilities for air quality managers to monitor and manage air quality. These capabilities include collecting emissions data from distributed emissions sensors (included in ITS Roadway Equipment in CVRIA) and directly from connected vehicles. The sensors monitor general air quality and also monitor the emissions of individual vehicles on the roadway. The measures are collected, processed, and used to support environmental monitoring applications.

This profile describes applicable standards for communicating between with ITS Roadway devices using the simple network management protocol (SNMP).




This profile describes an alternative set of standards used to communicate with ITS Roadway Devices that uses the NTCIP Octet Encoding Rules (OER), a standard developed specifically for the transportation industry. This template is used primarily for communication with traffic signal controllers, where second-per-second communications is required. This template also includes standards for SNMP traps, that allows an ITS Roadway Device to initiate event-driven communications with a receiver.
