Transit Management Center --> Transportation Information Center:
transit and fare schedules
Definitions
transit and fare schedules (Information Flow): Transit service information including routes, schedules, and fare information. This also includes on-demand service information.
Transit Management Center (Source Physical Object): The 'Transit Management Center' manages transit vehicle fleets and coordinates with other modes and transportation services. It provides operations, maintenance, customer information, planning and management functions for the transit property. It spans distinct central dispatch and garage management systems and supports the spectrum of fixed route, flexible route, paratransit services, transit rail, and bus rapid transit (BRT) service. The physical object's interfaces support communication between transit departments and with other operating entities such as emergency response services and traffic management systems.
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. | While accuracy of this data is important for decision making purposes, the greatest impact if manipulated or incorrect data would be financial and likely limited in scope. For example, making all options appear less expensive than an attacker's route of fiduciary interest, driving revenue to his route. This is undesireable and significant, but not catastrophic. Thus MODERATE generally. | While accuracy of this data is important for decision making purposes, applications should be able to function without frequent updates. Thus MODERATE generally, though it could be LOW depending on the level of projected updates. |
