The invention relates to the technical field of highway traffic flow prediction, and discloses a highway traffic flow prediction method based on weather conditions, which comprises the following steps: taking a road section between two entrances in the middle of a highway section as a predicted road section; according to video recording, the number of vehicles running on the predicted road section is obtained; predicting vehicle passing time according to the predicted road section; the highway traffic flow prediction method based on the weather condition comprises the following steps: step 1, testing vehicle passing time in extreme weather, step 2, carrying out vehicle statistics on a peak time domain and a normal time domain of a predicted road section, and generating a table, and comprises the following steps: obtaining the predicted road section, obtaining the vehicle quantity, driving a vehicle from the predicted road section, and testing the vehicle passing time in extreme weather. According to the highway traffic flow prediction method based on the weather conditions, vehicle passing tests are carried out on different extreme weathers, different intervals are divided, and statistical recording is carried out on the speeds and the vehicles in the different intervals, so that a worker can predict the traffic flow of the highway more conveniently when the extreme weathers occur.
