Abstract
The vehicle increase prediction was discussed in the article. Starting from the actual situation and the characters of vehicle increase on the highways, various factors such as the large base of vehicle amount, the increase of average income, rural vehicle amount, the enhancement of comprehensive vehicle amount and the increase phenomena of vehicle purchase by young people to impact the vehicle increase on highways were considered comprehensively, and the statistical analysis were made aiming at these factors one by one, and the impacts of these factors on the vehicle increase on highways and the concrete impacting modes were discussed, and the vehicle increase model were established and improved. By the statistical software SPSS, the regression analysis of the curve parameter estimation was made to confirm the function form of the concrete curve, and the Mathematica and Matlab were used to confirm the parameters and influences of various factors in the model by a series of data fitting, and the final model were established.
Highlights
The vehicle increase prediction was discussed in the article
Some new characters have occurred in the development of the vehicle on highways in recent years, and the increase of amount, the continual rise of the ratio of different vehicles, the average income and other factors all influence the increase of vehicle on highways
Evaluation and extension of the model. This model comprehensively considers the influences of numerous factors on the vehicle increase speed in China, and a comprehensively general mathematical model about the vehicle increase is established
Summary
Some new characters have occurred in the development of the vehicle on highways in recent years, and the increase of amount, the continual rise of the ratio of different vehicles, the average income and other factors all influence the increase of vehicle on highways. 2. Hypotheses of the problem (1) Under normal situation, there are not large numerous of vehicles to enter and quit. (3) The ideal vehicle entering and quitting proportion is about 1:1, and this proportion will not influence the settlement of the problem. (6) The speed of vehicle increase v is proportional to the base amount of vehicle. (8) The level of vehicle is higher, and the increase speed of vehicle amount is slower. (9) It is generally to think that the unreasonable structure of vehicle increases the increase of vehicle on highways
