摘要： A navigation system includes a display which provides a 3-D perspective view. The angle of viewing in the perspective view is increased based upon the complexity of the intersection being displayed. Intersections of increased complexity are displayed at an increased viewing angle to facilitate understanding. A sky above a horizon on the display changes color based upon the time of day.

摘要： A navigation system is used to assist a user in proceeding from a current location to a desired destination. The navigation system includes a processor for storing a database of roads and a system for determining the current position of a vehicle in relation to the database. A user can select a desired destination in the database by using an input device which sends the selection to the processor. The navigation system determines a route to the selected destination. An output device displays the route and the vehicle's current position by automatically scaling the display to include the route and the current position.

摘要： In a navigation apparatus Anavil, a CPU 1 searches for a plurality of routes from a starting point to a destination. Those route share the same starting point and the destination, but vary in course on the way. Then for route selection, the CPU 1 refers to position information provided by a locator 9 to determine which route the user is now moving. In this manner, the navigation apparatus can automatically select one route from several others derived through route search.

摘要： An Integrated Routing/Mapping Information System (IRMIS) links desktop personal computer cartographic applications to one or more handheld organizer, personal digital assistant (PDA) or “palmtop” devices. Such devices may be optionally equipped with, or connected to, portable Global Positioning System (GPS) or equivalent position sensing device. Desktop application facilitates user selection of areas, starts, stops, destinations, maps and/or point and/or route information. It optionally includes supplemental online information, preferably for transfer to the PDA or equivalent device. Users' options include route information, area, and route maps. Maps and related route information are configured with differential detail and levels of magnitude. Used in the field, in conjunction with GPS receiver, the PDA device is configured to display directions, text and map formats, the user's current position, heading, speed, elevation, and so forth. Audible signals identifying the next turn along the user's planned route are also provided. The user can pan across maps and zoom between two or more map scales, levels of detail, or magnitudes. The IRMIS also provides for “automatic zooming,” e.g., to show greater detail or closer detail as the user approaches a destination, or to larger scale and lower resolution to show the user's overall planned route between points of interest. The IRMIS also enables the user to mark or record specific locations and/or log actual travel routes, using GPS position information. These annotated location marks and/or “breadcrumb” or GPS log data can be saved, uploaded, displayed, or otherwise processed on the user's desktop geographic information or cartographic system. The IRMIS application and data may be distributed online and/or in tangible media in limited and advanced manipulation formats.

摘要： When a facility is specified from a facility list indicating facilities which satisfy a facility searching condition, a path searching processing section searches for a driving path with the specified facility being set as a destination, and obtains information such as driving distance and driving time required when a vehicle travels the driving path to the destination. A text-information generating and drawing section generates drawing data for displaying text information, such as the driving distance and the driving time, and stores the drawing data in a VRAM. A map drawing section generates drawing data for displaying a map image of an area which includes the driving path and stores the drawing data in the VRAM. An image synthesis section synthesizes the drawing data stored in the VRAM and the drawing data supplied from an operation-screen generation section, and causes a display apparatus to display a search image which includes the facility list, the text information, and the map image on one screen.

摘要： Humans identify location and directions based on visual cues, such as landmarks, rather than a precise coordinate grid. A database of landmarks can be used to determine the location of a user who can merely describe their location in the same manner they would to any human contact. The location of the user can be determined based on the landmarks described in the input, and the areas from which all of those landmarks are visible. Various databases can be used, including text-based and three-dimensional. Similarly, various mechanisms can be used to determine the user's location, including hierarchical approaches, query optimization approaches, and visibility percentage approaches. Ultimately, the user's location can be determined without the need for expensive, dedicated infrastructure, without compromising the user's security, and without subjecting the user to system outages.

摘要： A method for representing a route along a road network in a geographic region is disclosed. A database includes data representations of intersections of roads in the geographic region. Associated with the data representation for each intersection of roads are data indicating one or more nominal paths through the intersection. The nominal paths through an intersection identify, for each road segment by which the represented intersection can be entered, one and only one road segment from which the represented intersection is exited. The route is represented by indicating each intersection at which the route deviates from the nominal path into the intersection.

摘要： A navigation system provides information about railroad crossing locations. A geographic database used by the navigation system includes data that indicate whether an at-grade railroad crossing is located along a road segment. Using this information, a route calculation function in the navigation system calculates a route to a destination that avoids road segments that have at-grade railroad crossings. In this way, the delays associated with waiting for a train to cross a road are avoided.

摘要： When an approaching crossroad is detected on a target route, the method and apparatus of the invention determine if the relevant turn signal is operated before the crossroad, as well as informing the driver of the crossroad. According to the invention, if the relevant turn signal is not operated, routes different from the target route are calculated before the vehicle arrives at the crossroad, and if the vehicle does not follow the target route at the crossroad, the target route is changed according to the vehicle position.
