The invention relates to the technical field of artificial intelligence, is applied to the field of smart cities, and discloses a tracing method and device based on a road condition state prediction model, computer equipment and a storage medium. The method comprises steps of acquiring a real-time image; inputting the real-time image into a road condition state prediction model to obtain a predicted road condition level; acquiring a specified tail gas concentration calculation formula; calculating the simulated tail gas pollution concentration, and constructing a simulated tail gas pollution concentration sequence [A1, A2,..., An]; obtaining the real tail gas concentration, and constructing a real tail gas concentration sequence [C1, C2,..., Cn]; calculating a Pearson correlation coefficient value; if the Pearson correlation coefficient value is greater than a coefficient threshold value, judging that an automobile of the specified automobile type is the main source of tail gas pollution, and adding the specified automobile type into a traffic control list. The method is advantaged in that the main source of tail gas pollution is found out and limited, control efficiency of tail gas pollution is improved, in addition, the invention further relates to a blockchain technology, and a road condition state prediction model can be stored in a blockchain.
