DDOE Air Quality Division - Emissions Management Functionality
Subsystem Description
This subsystem operates at a fixed location and may co-reside with the Traffic Management Subsystem or may operate in its own distinct location depending on regional preferences and priorities. This subsystem provides the capabilities for air quality managers to monitor and manage air quality. These capabilities include collecting emissions data from distributed emissions sensors within the roadway subsystem. These sensors monitor general air quality within each sector of the area and also monitor the emissions of individual vehicles on the roadway. The sector emissions measures are collected, processed, and used to identify sectors exceeding safe pollution levels. This information is provided to traffic management to implement strategies intended to reduce emissions in and around the problem areas. Emissions data associated with individual vehicles, supplied by the Roadway Subsystem, is also processed and monitored to identify vehicles that exceed standards. This subsystem provides any functions necessary to inform the violators and otherwise ensure timely compliance with emissions standards.
Functional Area: Emissions Data Collection
Collection and storage of air quality and emissions management information. For use by operations personnel or data archives in the region.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall collect air quality and emissions management data from various sources, including emissions sensors distributed along the roadside and wide-area sensors detecting pollution over a larger geographical area. | Planned |
| 2 | The center shall assign quality control metrics and meta-data to be stored along with the data. Meta-data may include attributes that describe the source and quality of the data and the conditions surrounding the collection of the data. | Planned |
| 3 | The center shall receive and respond to requests from ITS Archives for either a catalog of the emissions management data or for the data itself. | Planned |
| 4 | The center shall be able to produce sample products of the data available. | Planned |
Functional Area: Emissions Data Management
Assimilation and storage of air quality measures and roadside collected emissions data; distribution for general traveler information or for use in demand management programs.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall collect, analyze, and store vehicle emissions data collected from roadside sensors. | Planned |
| 2 | The center shall collect, analyze, and store wide area pollution data collected from sensors that may the general (wide area) environment. | Planned |
| 3 | The center shall configure and control emissions and air quality sensors located in the field. | Planned |
| 4 | The center shall maintain a database of pollution reference data including acceptable and tolerable emissions and pollution levels for the area served by the center. | Planned |
| 5 | The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for emissions. | Planned |
| 6 | The center shall establish violation parameters, detect emissions violators, obtain the vehicle registration data from the appropriate State Department of Motor Vehicles (DMV) office, and then provide the capability to send violation information to a law enforcement agency. | Planned |
