TI08: Personal Wayfinding

This service package provides tailored wayfinding information in response to a traveler request. Both real-time interactive request/response systems and information systems that "push" a tailored stream of information to the traveler based on a submitted profile are supported. The traveler can obtain current information regarding pathways (e.g., sidewalks, bike lanes, moving sidewalks), open areas (e.g., pedestrian plazas, parking lots), indoor facilities, and crosswalks. The service package also offers the user pre-trip and en-route guidance services for wayfinding and navigation. It generates a wayfinding plan based on traveler preferences and constraints. Routes may be based on static information or reflect real time pathway conditions. The route determination function may be performed by the center or in the personal device. The wayfinding plan may include specific routing information that can be supplied to the traveler as general directions or as turn-by-turn route guidance depending on the level of user equipment.

Includes Physical Objects:

Physical Object Class Description
Alternate Mode Transportation Center Center 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.
Maint and Constr Management Center Center The 'Maint and Constr Management Center' monitors and manages roadway infrastructure construction and maintenance activities. Representing both public agencies and private contractors that provide these functions, this physical object manages fleets of maintenance, construction, or special service vehicles (e.g., snow and ice control equipment). The physical object receives a wide range of status information from these vehicles and performs vehicle dispatch, routing, and resource management for the vehicle fleets and associated equipment. The physical object participates in incident response by deploying maintenance and construction resources to an incident scene, in coordination with other center physical objects. The physical object manages equipment at the roadside, including environmental sensors and automated systems that monitor and mitigate adverse road and surface weather conditions. It manages the repair and maintenance of both non-ITS and ITS equipment including the traffic controllers, detectors, dynamic message signs, signals, and other equipment associated with the roadway infrastructure. Weather information is collected and fused with other data sources and used to support advanced decision support systems.

The physical object remotely monitors and manages ITS capabilities in work zones, gathering, storing, and disseminating work zone information to other systems. It manages traffic in the vicinity of the work zone and advises drivers of work zone status (either directly at the roadside or through an interface with the Transportation Information Center or Traffic Management Center physical objects.)

Construction and maintenance activities are tracked and coordinated with other systems, improving the quality and accuracy of information available regarding closures and other roadway construction and maintenance activities.
Other Transportation Information Centers Center Representing another Transportation Information Center, this object is intended to provide a source and destination for ITS information flows between peer information and service provider functions. It enables cooperative information sharing between providers as conditions warrant.
Pathway Communications Unit Field The 'Pathway Communications Unit' provides wireless communications between the pathway infrastructure (either indoor or outdoor) and nearby mobile devices; Communications with adjacent field equipment (including other PCUs) and back-office centers that monitor and control the PCU are also supported. The PCU provides basic radio communications supporting the lower layers of the OSI stack (TransNet and SubNet layers of the ARC-IT communications model). Importantly, it can also serve as a reference for mobile devices to determine their position more accurately (e.g., through triangulation or other means).
Pathway Equipment Field 'Pathway Equipment' represents the equipment that is distributed along pathways that monitors and supports movement on the pathways and interfaces with electronic devices used by travelers on the pathways. This physical object includes elevators, escalators, electronic turnstiles, pedestrian (and other VRU) detectors, electronic signage, electronic waypoints, and warning systems for pathway users.
Personal Information Device Personal The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.
Personal Safety Device Personal Personal Safety Device represents devices used by travelers (vulnerable road users) to support safe wayfinding. A personal safety device could include wearables like a specialized vest, backpack, cane, or any other safety peripheral used to enhance the safety of travelers while traveling along pathways.
TIC Operator Center This 'TIC Operator' represents the person or people that monitor and manage traveler information services provided by the Transportation Information Center.
Transit Management Center Center 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 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 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.
