Navigation data provision system, navigation server and navigation terminal

Abstract: A navigation data provision system comprises: a broadcasting business facility for the dissemination of broadcast data that, at the least, includes drive plan data; a navigation business facility which selects, from the drive plan data, at least one set of drive plan data that matches user preference data; and a navigation terminal which receives the drive plan data and which employs the drive plan data to help prepare a route guide for a vehicle.

Dynamic Optimal Route Search Algorithm for Car Navigation Systems with Preferences by Dynamic Programming

Abstract: Optimal route search to the destination is one of the most important functions of car navigation devices. The development of road traffic infrastructure has made it possible to receive real-time information of the traffic situation. Route search algorithms for car navigation devices make use of this information to avoid the traffic congestions. Such algorithms should find the new optimal route efficiently when the traffic situation changes. Usually, the minimum traveling time or distance is considered to define the optimal route. However, the minimum traveling time or distance is not always what the user is looking for. The user may prefer to travel on a certain route even at the cost of traveling time or distance. Car navigation devices should consider such preferences when finding the optimal route. In this paper, we propose a dynamic programming algorithm to find the optimal route considering that it should deal with the changes of the traffic situation and multiple criteria. The proposed method uses the information from the previous computation to find the new optimal route considering user preferences when the traveling time of the road section changes. The proposed method was applied to a real road network to find the optimal route. Results show that the proposed method can find the user-preferred optimal route. Simulation results also show better calculation time of the proposed method compared to the Dijkstra algorithm. Copyright © 2010 Institute of Electrical Engineers of Japan.

Site Structure and User Navigation: Models, Measures and Methods

Abstract: The analysis of the structure of Web sites and patterns of user navigation through these sites is gaining attention from different disciplines, as it enables unobtrusive discovery of user needs. In this chapter we give an overview of models, measures, and methods that can be used for analysis purposes as well as for user-adaptive navigation support. Specific attention is given to the problem of identifying users getting lost. We conclude with a discussion on various personalised navigation aids that benefit from the techniques presented in this chapter.

Navigation system providing lane guidance to driver based on driver's driving habits and preferences

Abstract: A method, system and computer program product for providing lane guidance to a driver of a vehicle. Based on the current location of the vehicle, the navigation system determines a route to travel from the current location of the vehicle to a destination provided by the driver. The navigation system obtains one or more of the following types of information which is used to determine whether the navigation system should recommend a lane change: past driving patterns of the driver, driver's lane preferences, past driving history of other drivers on the route, external conditions (e.g., weather) and features of the route. The recommendation may be presented to the driver via an audio instruction and/or on a display. In this manner, the navigation system instructs the driver as to which lane in a multi-lane road the user should drive on taking into consideration the user's driving habits and preferences.

Audio/navigation system with automatic setting of user-dependent system parameters

Abstract: The invention proposes an audio and/or navigation system for a motor vehicle with increased user convenience, particularly when the vehicle is used by more than one user. The audio and/or navigation system has a memory element ( 2 ) for storing user-related system parameters, and means ( 4 ) for identifying the user as well as means ( 5 ), which are connected to the memory element ( 2 ), for selecting and setting the stored user-related system parameters for the user as current system parameters.
