Transportation Information Center --> Alternate Mode Transportation Center:
service information request

Definitions

service information request (Information Flow): Request to multimodal (possibly non-roadway) transit provider for general services information and specific trip information or reservation.

Transportation Information Center (Source 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.

Alternate Mode Transportation Center (Destination Physical Object): The 'Alternate Mode Transportation Center' provides the interface through which non-ITS transportation systems (e.g., airlines, ferry services, passenger-carrying heavy rail) can exchange data with ITS. This two-way interface enables coordination for efficient movement of people across multiple transportation modes. It also enables the traveler to efficiently plan itineraries which include segments using other modes.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: TCIP - Secure Internet (ITS)

Solution Description

This solution is used within the U.S.. It combines standards associated with US: TCIP with those for I-I: Secure Internet (ITS). The US: TCIP standards include upper-layer standards required to implement transit-related communications. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Rating Moderate Moderate Low
Basis Individual service response implies activity by an individual, which could be PII. Confirmation of service to be provided needs to be intact so that the end transportation user does not make alternate arrangements, but given that this is an individual, the impact to the overall system should be minimal. Could be low. If the information never arrives the service might still take place. Worst case, the user makes new arrangements with low impact to everyone but him and the provider.
