Abstract:
A navigation apparatus (200) comprises a processing resource (260) configured to: determine a route to a selected destination; obtain weather-related data; and modify speed data for a plurality of route segments in dependence on the weather-related data. For each route there is a respective classifier that classifies the road type for the route segment, and the processing resource is configured to modify the speed data for each route segment based on the weather-related data and the road type represented by the classifier for that route segment.
Abstract:
A navigation system comprises a processing resource (202) configured to receive destination data representative of a destination, to determine an expected travel time to the destination, and to determine a departure time in dependence upon the expected travel time to the destination, and an output device (206) for providing the departure time to a user.
Abstract:
A navigation device includes a route determiner module to formulate a first route from a first geographic location to a second geographic location. A route presentation module presents the first route to a user of the navigation device. A side trip presentation module presents a point-of-interest to the user of said navigation device and formulates a second route to said point-of- interest. An options module presents an option, during presentation of the first route, to recalculate the first route to the second geographic location to comprise the second route.
Abstract:
The accuracy of a reverse geocode for a GPS fix in a mobile phone navigation device is improved significantly by considering together the user's last known location on an original route, the elapsed time between the last known location on the original route and the latest GPS fix, and the likelihood that the user could have travelled from the last known location on the original route to one of numerous candidate locations (generated from the reverse geocode) in the elapsed time. The navigation server relies only on a GPS fix, timestamps, and a back-end routing database to provide improved or superior accuracy of reverse geocoding a GPS fix (selection of a point on a road) when a relevant user has deviated from the intended route. The reverse geocoding allows for accurate and functional re-routing capabilities.
Abstract:
Embodiments of the present invention provide a navigation apparatus (200), comprising: a data storage means (214); a processor (202); and a display device (206) controlled by the processor (202), wherein the processor (202) is arranged to store in the data storage means (214) information indicative of one or more previous routes followed by the navigation apparatus; and the processor (202) is arranged to influence subsequent operation of the navigation apparatus (200) according to a current location of the navigation apparatus and the stored information.
Abstract:
A method for a detour route search, the method including: receiving destination information of a moving object in a navigation terminal performing a geographical guidance; extracting, from a database, location information corresponding to the received destination information; and displaying map group information that includes at least one route information, based on the extracted location information corresponding to the destination information is provided.
Abstract:
Methods and apparatus, including computer program products, for a supplemental powered information receiver. A system includes a processor linked to a memory, the memory including at least a Global Positioning System (GPS) navigation process, a clock and internal timer linked to the processor, a programmable power source linked to the processor, and an information receiver module linked to the processor, the information receiver module receiving information when programmed to power up into a standby mode.
