Traveler Information Devices - Personal Information Device Functionality

Subsystem Description

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 connected vehicle on–board equipment.

Functional Object: Personal Data Subscription Management

'Personal Data Subscription Management' manages data subscriptions for an end user. It provides access to a catalog of available data, manages the necessary user information and rules that govern the data subscriptions, supports communications with data providers to collect data per the subscription rules, and makes the data available to the end user. It provides the local user interface through which a user can specify and manage subscriptions. It supports different mechanisms for collecting data for the end–user including one–time query–response as well as publish–subscribe services.

Functional Object: Personal Interactive Traveler Information

'Personal Interactive Traveler Information' provides traffic information, road conditions, transit information, yellow pages (traveler services) information, special event information, and other traveler information that is specifically tailored based on the traveler's request and/or previously submitted traveler profile information. It also supports interactive services that support enrollment, account management, and payments for transportation services. The interactive traveler information capability is provided by personal devices including personal computers and personal portable devices such as smart phones.

Functional Object: Personal Intersection Safety

'Personal Intersection Safety' improves pedestrian, cyclist, and other non–motorized user safety by providing personal location information to the infrastructure that can be used to avoid collisions involving non–motorized travelers. It may also alert the non–motorized user of unsafe conditions, augmenting or extending information provided by signals and signs. The information provided and the user interface delivery mechanism (visual, audible, or haptic) can also be tailored to the needs of the user that is carrying or wearing the device that hosts the application.

Functional Object: Personal Location Determination

'Personal Location Determination' receives current location information and provides this information to other applications that use the location information to provide guidance and emergency notification services. It interfaces with and encapsulates positioning technology such as a GPS receiver that is embedded in the user's device.

Functional Object: Personal Map Management

'Personal Map Management' supports map updates and makes current map and geometry data available to other applications. It manages map data for the device and provides map data to end–user applications that provide location–based services.

Functional Object: Personal Shared Use Planning

'Personal Shared Use Planning' provides a personalized connection to shared use mobility including vehicle shared use and arranging person trips. The shared use plan is calculated based on preferences and constraints supplied by the traveler and provided to the traveler for confirmation. Many equipment configurations are possible including systems that provide a basic trip plan to the traveler as well as more sophisticated systems that can provide transition by transition guidance to the traveler along a multi–modal route with transfers. Devices represented by this functional object include desktop computers at home, work, or at major trip generation sites, plus personal devices such as tablets and smart phones.

Functional Object: Personal Traveler Information Reception

'Personal Traveler Information Reception' receives formatted traffic advisories, road conditions, traffic regulations, transit information, broadcast alerts, and other general traveler information broadcasts and presents the information to the traveler. The traveler information broadcasts are received by personal devices including personal computers and personal portable devices such as smart phones.

Functional Object: Personal Trip Planning and Route Guidance

'Personal Trip Planning and Route Guidance' provides a personalized trip plan to the traveler. The trip plan is calculated based on preferences and constraints supplied by the traveler and provided to the traveler for confirmation. Coordination may continue during the trip so that the route plan can be modified to account for new information. Many equipment configurations are possible including systems that provide a basic trip plan to the traveler as well as more sophisticated systems that can provide transition by transition guidance to the traveler along a multi–modal route with transfers. Devices represented by this functional object include desktop computers at home, work, or at major trip generation sites, plus personal devices such as tablets and smart phones.
