| 20100174482 | NAVIGATION SERVER - A navigation server for assisting guidance of moving objects such as automobiles by a navigation device while considering the level of safety of each link in the area where a disaster has occurred and adequately evaluating the safety in consideration of the actual disaster situation. A navigation service extracts links included in a disaster area and evaluates the cost of each of the extracted links according to probe information. The probability of reflection of the adverse influence of the disaster on spatial and temporal movement patterns of an automobile represented by the probe information is high. Therefore, the level of safety of each link in the disaster area can be adequately evaluated so that the adverse influence of the disaster can be avoided. | 07-08-2010 |

| 20100198454 | TRAFFIC INFORMATION PROCESSING APPARATUS, TRAFFIC INFORMATION MANAGEMENT SERVER, TRAFFIC INFORMATION MANAGEMENT SYSTEM - Provided is an apparatus and the like for improving the communication efficiency of travel information and the like by taking account of the degree of necessity of collecting the travel information of a vehicle in view of an operating state or attribute of the vehicle. A traffic information processing apparatus ( | 08-05-2010 |
| 20100198500 | NAVIGATION DEVICE, NAVIGATION SERVER AND NAVIGATION SYSTEM - A navigation device and the like capable of harmonizing a navigation route for guiding a mobile body set on the basis of a support route search result by a navigation server and a navigation route for also guiding the mobile body set independently of the navigation route, from a view point of guiding the mobile body smoothly. In the case where the second navigation route r | 08-05-2010 |
| 20100223001 | NAVIGATION APPARATUS, NAVIGATION SERVER, AND NAVIGATION SYSTEM - Provided is a navigation system capable of outputting situation information of a specified area according to real-time traffic information including a traffic regulation. A navigation apparatus can make a user recognize the moment when a vehicle (Q) enters a specified area (A) where a situation which affects the travel of the vehicle (Q) along a navigation route (r) is generated and the situation (inf(A)) indicating the situation by using an icon (x) indicating an entry position (p | 09-02-2010 |
| 20100286906 | NAVIGATION SERVER, NAVIGATION APPARATUS, AND NAVIGATION SYSTEM - Provided is a navigation system capable of matching map information used by a navigation apparatus and a navigation server with an appropriate frequency and at an appropriate timing. When there is differential information between the navigation map information and the support map information, index information for identifying the differential information is transmitted from the navigation server to the navigation apparatus and the navigation apparatus outputs preliminary information indicating a brief summary of the differential information generated according to the index information. When a request signal based on a request operation by a user in the navigation apparatus is transmitted from the navigation apparatus to the navigation server, the differential information is transmitted form the navigation server to the navigation apparatus, so that the navigation map information is updated in accordance with the differential information. | 11-11-2010 |
