It can obtain the latest high-precision road network map from the road network map system or GIS system; and divide each road on the map into map grids based on the high-precision road network map, forming a corresponding map road network from all the map grids of each road. Because the map road network originates from the high-precision map, each map grid in the map road network has a corresponding map grid address. After obtaining the map road network corresponding to all roads, the traffic and meteorological cloud platform 4 can construct historical traffic information networks and historical meteorological information networks accordingly.
[0071] In the constructed historical traffic information network, each first road network corresponds to a map road network, each first grid corresponds to a map road network, the location information of each first grid corresponds to a map grid address, and the road information of each first grid corresponds to the road identifier of the road where the map grid is located.

The system generates corresponding first predicted temperature, humidity, road surface temperature, air pressure, wind force and direction, and precipitation sequences based on air humidity, road surface temperature, air pressure, wind force and direction, and precipitation. Then, based on the known predicted time point sequences for a second future specified period and the corresponding first predicted temperature, humidity, road surface temperature, air pressure, wind force and direction, and precipitation sequences, it performs predictions on each second predicted record in the second prediction list of the fourth grid corresponding to the current grid in the meteorological information network.
