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 Center 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.
Traveler Personal The 'Traveler' represents any individual who uses transportation services. The interfaces to the traveler provide general pre-trip and en-route information supporting trip planning, personal guidance, and requests for assistance in an emergency that are relevant to all transportation system users. It also represents users of a public transportation system and addresses interfaces these users have within a transit vehicle or at transit facilities such as roadside stops and transit centers.
Traveler Information Voice System Center The 'Traveler Information Voice System' provides the caller interface and voice processing (voice recognition/synthesis) that supports voice-enabled traveler telephone information systems. It provides wireline and wireless caller access to 511 systems and other telephone access mechanisms like 7 or 10 digit local access numbers. It represents the boundary of the architecture where a call is received and processed and includes voice portal capabilities in scenarios where a distinct voice portal exists between ITS Centers and telecommunications providers. The terminator gathers traveler information, alerts, and advisories from information service provider(s) and uses this information to support voice-based interactions with a traveler.
Traveler Support Equipment Field 'Traveler Support Equipment' provides access to traveler information at transit stations, transit stops, other fixed sites along travel routes (e.g., rest stops, merchant locations), and major trip generation locations such as special event centers, hotels, office complexes, amusement parks, and theaters. Traveler information access points include kiosks and informational displays supporting varied levels of interaction and information access. At transit stops this might be simple displays providing schedule information and imminent arrival signals. This may be extended to include multi-modal information including traffic conditions and transit schedules to support mode and route selection at major trip generation sites. Personalized route planning and route guidance information can also be provided based on criteria supplied by the traveler. It also supports service enrollment and electronic payment of transit fares. In addition to the traveler information provision, it also enhances security in public areas by supporting traveler activated silent alarms.

This data is informing the driver about the safety of a nearby area. It should not contain anything sensitive, and does not matter if another person can observe it. This is the information that is presented to the driver. If they receive incorrect information, they may act in an unsafe manner. However, there are other indicators that would alert them to any hazards, such as an oncoming vehicle or crossing safety lights. If this information is not made available to the driver, then the system has not operated correctly.
Light Vehicle OBE Transportation Information Center traveler request Moderate Moderate Moderate
This is likely to include the traveler location and may include traveler identity as well. This PII could be used by an attacker to the detriment of the traveler. Request needs to be correct, or the wrong data may be sent. Interface needs to be available or users will find other sources that are reliable.

Other Transportation Information Centers Transportation Information Center parking information Moderate Moderate Moderate
Does not include PII, but does include usage information for a managed facility that implies a number of vehicles. While this is observable information, it could be considered competitive, and regardless is accessible without being physically present, which is its own barrier. Generally transportation coordination information should be correct between source and destination, or inappropriate actions may be taken. Most likely not a frequently updated flow. Typically MODERATE for applications with a high degree of commercial vehicle parking, but could be LOW otherwise.
Other Transportation Information Centers Transportation Information Center road network conditions Low Moderate Moderate
No harm should come from seeing this data, as it is eventually intended for public consumption. While accuracy of this data is important for decision making purposes, applications should be able to corroborate the data in many instances. Thus MODERATE generally. Depends on the application; if mobility decisions that affect large numbers of travelers are made based on this data, then it is MODERATE. In more modest circumstances, it may be LOW.
Other Transportation Information Centers Transportation Information Center traffic image meta data Low Moderate Moderate
Traffic image data is generally intended for public consumption, and in any event is already video captured in the public arena, so this must be LOW.
