The invention discloses a path navigation method, relates to the technical field of intelligent traffic information service, and solves the problem that a user cannot avoid severe weather when passing through a navigation path as a weather situation is not combined with path navigation in the prior art. The method includes the steps: acquiring raster data carrying weather information data according to preset time intervals; determining that the raster data are dangerous weather information data when the weather information data in a raster are larger than a preset threshold value; acquiring central point coordinates of an exterior rectangle of each path unit in an appointed path; building an identity table according to the central point coordinates and coordinate data of the dangerous weather information data; and determining path navigation information according to the identity table and departure place, destination and referring weather conditions transmitted by a terminal, and transmitting the path navigation information to the terminal. The path navigation method is applied to the path navigation process.
Description
technical field [0001] The invention relates to the technical field of intelligent traffic information services, in particular to a route navigation method. Background technique [0002] With the rapid development of the traffic information service industry, the scope of traffic information has expanded from the traditional simple road condition information to road travel information. Weather information is also an indispensable reference information for vehicles and people traveling in cities, especially urban The cross-city driving of inter-city vehicles puts forward higher requirements for real-time and forecast information of weather conditions. [0003] In the existing route navigation technology, only according to the starting point, destination, weather conditions and avoidance route set by the user, provide the user with a new route that is more in line with the requirements, and provide the weather conditions of the area where the new route passes, and there is no ...
