Embodiment Construction
[0041] refer to figure 1 , figure 1 is an implementation flow chart of a method for urban road navigation provided by an embodiment of the present invention, the method is applied to a terminal, such as figure 1 The shown method for urban road navigation may include the following steps:
[0042] S101, the server obtains the accumulated water detection information uploaded by multiple water level detectors, and the accumulated water detection information carries position coordinates and accumulated water depth;
[0043] It should be noted that, when the server receives the weather forecast information acquisition instruction, it sends an authentication request message to the preset weather forecast platform, and the authentication request message carries the unique identification code of the server; the weather forecast platform according to The authentication request message authenticates the acquisition of weather forecast information by the server to determine whether the ...

The invention belongs to the technical field of intelligent transportation, and provides an urban road navigation method and system. The method comprises the following steps that: a server obtains accumulated water detection information uploaded from a plurality of water level detectors; according to position coordinates in the accumulated water detection information uploaded from the water leveldetectors, the depth of accumulated water in the same road section is obtained, and the maximum value of the depth of accumulated water in the same road section is used as the depth of accumulated water of the road section; when a navigation request uploaded from a navigation terminal is received, a plurality of navigation routes are selected; safe fording depth corresponding to a vehicle model number uploaded from the navigation terminal is obtained; according to the fording depth of each road section in the navigation route, the safe fording depth corresponding to the vehicle model number uploaded from the navigation terminal, and a preset safety factor generation model, the safety factor of the navigation route is generated; and the safety coefficient of each navigation route is sorted,and the navigation route which ranks first is pushed to the navigation terminal. By use of the method, the travelling safety of rainy days can be improved so as to be favorable for improving a navigation route pushing effect.
Description
technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a method and system for urban road navigation. Background technique [0002] The underground construction in many cities is far behind the above-ground construction. In case of heavy rain, affected by the city's drainage capacity, a large amount of water will accumulate on the road section with a lower water level, forming a waterlogged road section. At the same time, in the process of urban road navigation, the server of the navigation map can plan a navigation route according to the starting point and destination input by the navigation terminal, and send the navigation route to the navigation terminal. [0003] However, the existing urban road navigation method does not take into account the water accumulation on the road in the navigation route, so that the pushed navigation route is not ideal. Specifically, during the navigation process, since...
