Emissions Management Center --> Transportation Information Center:
low emissions zone operations information for public
Definitions
low emissions zone operations information for public (Information Flow): Information on the state of transportation system operations within the low emissions zone including emissions zone parameters, traffic and road conditions within the zone, advisories, incidents, transit service information, weather information, parking information, and other related data. This version includes no detailed operational data (e.g., where the emissions sensors are located) that might be used to subvert the operation.
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.
Transportation Information Center (Destination Physical Object): The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.

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 | Generally, center-originating flows destined for a TIC don't contain any personal or confidential information, and are eventually intended for some kind of public consumption. | Important for low emissions zone operations; without accurate and timely information, travelers may be unaware of the restrictions in place for these areas. | Important for low emissions zone operations; without accurate and timely information, travelers may be unaware of the restrictions in place for these areas. |
