20120078511 | METHOD AND APPARATUS FOR PROVIDING DIRECTIONAL NAVIGATION INDICATION - A method and apparatus to enhance the direction navigation capabilities of GPS-enabled devices, through the use of light indicators is proposed. The light indicators are positioned on the top, bottom, and sides of the GPS screen. The light indicators blink at different rates relatively to a distance to a destination. The light indicators show various effects to indicate various instructions, such as to go forward direction, to go onto an overhead bridge, to enter into an underground tunnel. | 03-29-2012 |
20120136570 | Device and Method for Generating Route Restriction Information of Intersection, Computer Program for Generating Route Restriction Information of Intersection, and Recording Medium for Recording Computer Program - Provided are a device for automatically generating route restriction information of intersections between main roads and narrow streets, and a method therefor. With respect to a specific intersection which is an intersection between a main road and a narrow street, firstly, it is determined to prohibit a right turn and passing through the intersection. Under these conditions, when it is sufficiently confirmed, by using external information, that the right turn and passing through the intersection can be allowed at the specific intersection, the route restriction regarding the direction is released. Probe information and traffic restriction data are used for the external information. | 05-31-2012 |
20120150433 | SYSTEMS AND METHODS FOR CROSS-STREET IDENTIFICATION - Aspects of the invention relate to the use of electronic maps and providing information about intersecting streets. A given region of interest on a map may include any number of features. Features of interest, including road segments and intersections, can be filtered to remove non-street data. The results may be analyzed according to individual street segments. Each segment may be identified by a feature ID, and the relationship each segment has with a given intersection is analyzed. Thus, the direction of a segment into or out of an intersection is determined, along with the physical locations of the beginning and end of the segment. This information is used to provide robust map information that may be displayed to a user. Heuristics can be applied to the map information to provide coherent address or direction information to the user for a given point of interest. | 06-14-2012 |
20120158292 | User Configurable Onboard Navigation System Crossroad Presentation - A computer-implemented method for road identification includes receiving a request at a vehicle computing system for a crossroad identification. The method also includes determining, via the vehicle computing system, a crossroad along a route-being-traveled corresponding to the request. The method further includes outputting, from the vehicle computing system to an output, the determined crossroad responsive to the request. | 06-21-2012 |
20120197525 | NAVIGATION APPARATUS - A control circuit of a navigation apparatus acquires exit port information in a rotary intersection for route guidance. It is determined whether a guidance point or guidance target used as an exit path from the rotary intersection is a learned road acquired by the road learning function. When the exit path is not a learned road, namely, when the exit path is an existing road in a ready-made map data, an “exit path guidance for existing roads” aimed at an exit port to an existing road is executed. In contrast, when the exit path from the rotary intersection is a learned road, an “exit path guidance for learned roads” aimed at an exit port to a learned road is executed. | 08-02-2012 |
20140067259 | METHOD OF PROVIDING INTERSECTION ASSISTANCE AND RELATED PORTABLE ELECTRONIC DEVICE - A method of providing intersection assistance with a portable electronic device to remind a user of traffic rules when the user approaches traffic intersections includes receiving an input from the user indicating a destination location for generating navigation instructions to the destination location, determining a current location of the portable electronic device according to received position signals, providing navigation instructions to the destination location according to the current location of the portable electronic device, and reminding the user of traffic rules related to intersections for a geographical location in which the portable electronic device is currently located when the portable electronic device detects that the portable electronic device is approaching an intersection, where reminding the user of traffic rules related to intersections comprises indicating a side of a second road the user should turn onto when making a turn from a first road onto the second road. | 03-06-2014 |
20140244162 | Data Mining in a Digital Map Database to Identify Insufficient Merge Lanes Along Roads and Enabling Precautionary Actions in a Vehicle - Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle, in particular, an intersection without traffic signals and without a sufficient merge lane. A database that represents the road network is used to determine locations where roads meet without a traffic signal and without a sufficient merge lane. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken about the location of the insufficient merge lane. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching a location of an insufficient merge lane. | 08-28-2014 |
20140249748 | ROUTE GUIDANCE AT INTERSECTIONS - Various embodiments relate to techniques of providing route guidance along a planned route leading through at least one intersection. Predetermined attributes for a respective transition through the at least one intersection are retrieved from a database, the attributes specifying at least a curved path modelling a geometrical form of the transition. The curved path is displayed in a map view for route guidance along a planned route. | 09-04-2014 |
20150019128 | Method and System for Representing Traffic Signals in a Road Network Database - A method and system for representing traffic control signals in a road network database is provided. The database may include lane-level modeling, intersection modeling, and traffic signal modeling of a road network. An individual traffic signal is represented in the database with data indicating the traffic signal's geographic location and other attributes of the traffic signal such as an arrangement of lenses in the signal, an indication as to whether the signal is vertically or horizontally oriented, a height of the traffic signal over the roadway, and others. The database can be used by a system in a vehicle that provides convenience features to the vehicle's driver. The system may attempt to warn or control a vehicle that is determined to be at imminent risk of violating a traffic signal. | 01-15-2015 |

20160018238 | ROUTE INSPECTION PORTALS - One or more techniques and/or systems are provided for populating a map interface with a route inspection portal and/or for generating travel route video. In an example, a map interface is populated with a map canvas illustrating a travel route. The map canvas is populated with inspection markers corresponding to imagery depicting travel route portions of the travel route. Responsive to identifying a selection of an inspection marker at an inspection location, imagery depicting the inspection location may be identified. The map canvas is populated with a route inspection portal for the inspection marker. The route inspection portal is populated with the imagery (e.g., street-side imagery of an intersection along the travel route). In an example, a travel route video, comprising video frames corresponding to an ordering of the imagery (e.g., from a start location to an end location) along the travel route, may be generated and/or played. | 01-21-2016 |
