3 is a flowchart illustrating an example of a process of providing a route guidance service based on weather hazard information in a route guidance service server according to an embodiment of the present invention.

Here, it is assumed that the database 240 storing information used in the path search and supplementary information providing service described above in FIG. 2 is constructed in advance.

Referring to FIG. 3, the route guidance service server 200 according to the embodiment of the present invention collects road state information and traffic flow information that are checked in real time from the road / traffic information service server (S301) Past weather disaster information and meteorological disaster information to be measured in real time are collected from the server (S302).

At this time, the road / traffic information collection step S301 and the weather information disaster information collection step S302 are not limited to the flow shown in the drawings, and the position information (the current vehicle position, , Destinations, etc.), it is possible to prevent a surge in server load.

The route guidance service server 200 generates snowfall information, rainfall amount information, wind direction information, wind speed information, temperature information, humidity information, and the like, which can affect the running of the road by region, time, Information on fog information, irradiation amount information, tsunami / flood / fire / seismic information, and the like, geo-tagging the processed weather disaster information, and processing data so that it can be used for path search (S303).

At this time, it is possible to include a step of analyzing the road / traffic influence degree according to the meteorological disaster item as illustrated in Table 1 above.

Next, the map map table as illustrated in Table 2 above is applied to the processed weather disaster information to generate processed map information reflecting the weather disaster information (S304). The processed map information is obtained by applying one or more of various mapping items included in the map mapping table, and can reproduce the processed map by changing the mapping items according to the user selection.

The information according to the execution result in each of the above-described steps is stored and managed in the database 240 in a predetermined cycle or in real time.

Thereafter, the route guidance service server 200 searches for optimal route information reflecting weather disaster information, road / traffic information, and the like based on the database 240 and services the route information to the user terminal (S305). For example, route information that can reach the destination in the shortest time can be searched while detouring the route with poor route conditions based on the map information reflecting the degree of influence of the weather information on the road.

When searching for a route, the route guidance service server 200 generates additional information such as POI information, life information, safe driving information, and the like based on weather disaster information and road / traffic information based on the database 240, (S306). The additional information may be provided at the same time as the point in time when the route information is provided or at different points of time depending on the driving situation (for example, slowing down to a certain speed, selecting the user, sudden change of the weather disaster situation, etc.).

Further, the additional information may be provided on the same screen together with the path information served in the previous step (S305), or may be provided as a separate page.

The route search step S305 and the additional information service step S306 may be repeatedly performed in real time or at predetermined intervals until the user reaches the destination and the route guidance is terminated at step S307.

Specifically, FIG. 4 shows an example in which route guidance information reflecting meteorological disaster information is served, and route search is performed by mapping weather information according to the administrative / statutory schedule on a map.

Referring to FIG. 4, the route guidance service server services one or more recommended route information as a result of searching for a route reflecting meteorological disaster information and road / traffic information on the basis of location information transmitted from a user terminal driven by the application for route guidance service .

For example, as shown in FIG. 4, when rain or snow falls between the departure place A and the destination place B entered by the user, the route guidance service server geo-tagizes such weather information, The a section 401 having a numerical value or more can perform a route search in a detour direction to provide a recommended route.

The path # 1 402 bypasses the a section 401, which is difficult to travel safely due to a vehicle jamming phenomenon according to the current weather information, to the route searched according to the embodiment of the present invention. Among the other routes reaching the destination, This indicates the route that takes place. On the other hand, the second path 403 is a path search corresponding to the shortest distance from the starting point to the destination generally used in the path search in the conventional navigation system, and it can be confirmed that the path 401 includes the a period 401. That is, when the first route 402 and the second route 403 are compared with each other, the actual driver uses the first route 402 having the long travel distance, thereby bypassing the a section 401, Can be minimized.

In addition, the weather information can be provided to the user by including the image information 404 indicating the current weather information in a certain area on the page where the route guidance information is provided.

5 is a view showing another example of a mode in which a route guidance service according to an embodiment of the present invention is provided to a user terminal.

Referring to FIG. 5, a path search can be performed by analyzing road types constituting various paths from the source to the destination.
