Emissions Management Center --> Vehicle Operations and Service Center:
low emissions zone parameters
Definitions
low emissions zone parameters (Information Flow): The geographic boundaries, time period, and fee structure for a low emissions zone. This flow also provides the specific restrictions that are in place for the zone including admittance requirements and rules and restrictions for driving within the zone.
Emissions Management Center (Source 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) 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.
Vehicle Operations and Service Center (Destination Physical Object): 'Vehicle Operations and Service Center' (VOSC) represents centers that provide telematics services to vehicles using wide-area (e.g. cellular) communications, including traveler information, emergency services, vehicle diagnostics, over-the-air software updates, vehicle maintenance information and warnings, remote vehicle operation, and provision of service options for these vehicles. See also 'Transportation Information Center' that provides traveler information, trip planning, and routing services and 'Emergency Management Center' that provides call-taking and emergency response services that may also be implemented by a VOSC.

| Interoperability | Description |
|---|---|
| Regional | Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture). |

| Basis | This information is intentionally broadcast and is intended for public consumption. | Emissions zone information should have its integrity protected to avoid misinformation or confusion that could result from incorrect data dissemination. | Important for low emissions zone operations; without accurate and timely information, travelers may be unaware of the restrictions in place for these areas. | |
