Method of calculating route, and method or device for obtaining route |
摘要 |
A method of determining whether there is a need to re-calculate a trip route including a departure point and a destination by using traffic information according to an embodiment of the present invention is provided. The method is performed by a server and includes: receiving the current position from a terminal when the terminal moves a specific distance from a previously reported position; obtaining the current position of a third party when the destination is the position of the third party defined as the identifier (ID) of the third party; and determining whether there is a need to re-calculate the route according to a specific condition based on the obtained current position of the third party, wherein the specific condition is (1) when the third party moves a distance equal to or greater than a predetermined value from the previously reported position or (2) when the third party moves a distance equal to or greater than a predefined value from the previously reported position and the distance between the current position of the terminal and the current position of the third party is shorter than a critical value, and if one of the specific conditions is satisfied, it may be determined that there is a need to re-calculate the route. |

1. A method of, at a server, determining whether re-calculation of a route for a trip from a terminal to a destination is required using traffic information, the method comprising:
receiving a current location of the terminal from the terminal when the terminal moves from a previously reported location by a specific distance; acquiring a current location of a third party when the destination is a location of the third party defined by an identifier (ID) of the third party; and determining whether re-calculation of the route is required according to a condition based on the acquired current location of the third party, wherein the condition includes: when the third party does not move from the previously reported location more than a predetermined distance or more and a distance between the current location of the terminal and the current location of the third party is less than a threshold value, and wherein, if the condition is satisfied, a determination is made that re-calculation of the route is required. |
