In recent years, low-carbon logistics has received more and more attention, and the problem of cold chain logistics distribution route of fresh products under low-carbon conditions has also become a rsearch hotspot. Therefore, this paper adds carbon emission costs based on vehicle fixed cost, transportation cost, energy cost, cargo damage cost and time window penalty cost. Taking the minimum cost as the objective function and considering the traffic congestion that may occur in actual transportation, a low-carbon cold chain logistics distribution optimization model based on traffic congestion is proposed. By combining small-scale examples and using the optimization solver to solve the model, the analysis results show that the model is effective and practical in minimizing distribution cost.
