According to the statistics of Wuhan, the prediction model of vehicle population based on econometrics is established, the vehicle population of last year is especially considered in this model as a variable of representation of consumer psychology, and therewith regression coefficients and related statistic parameters are calculated through MATLAB in this paper, solid tests on the model are conducted as well.After model adjusted, the vehicle population of Wuhan in 2016 is eventuallycalculated.The result is comparative- ly accurate indicating it is a technically feasible method.The vehicle population of Wuhan in 2017 is predicted in this paper as well.
