alternate mode service coordination Quintuple

Bidirectional?: True

alternate mode service coordination (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'TIC Trip Planning' application object and the 'Alternate Mode Transportation Center' physical object. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

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.

TIC Trip Planning (Source Application Object): "TIC Trip Planning" provides pre-trip and en-route trip planning services for travelers. It receives origin, destination, constraints, and preferences and returns trip plan(s) that meet the supplied criteria. Trip plans may be based on current traffic and road conditions, transit schedule information, and other real-time traveler information. Candidate trip plans are multimodal and may include vehicle, transit, and alternate mode segments (e.g., rail, ferry, bicycle routes, and walkways) based on traveler preferences. It also confirms the trip plan for the traveler and supports reservations and advanced payment for portions of the trip. The trip plan includes specific routing information and instructions for each segment of the trip and may also include information and reservations for additional services (e.g., parking) along the route.

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.
