A Study of the Impact of Limitation of the Amount of Vehicles in Beijing Based on Mathematic Modeling

In order to study the limitation of the amount of vehicles in Beijing and especially the impact of "Lottery" policy for controlling the car growth in Beijing, a mathematic model was built to simulate the current car growth in Beijing and compare the growth model with the Logistic growth model to see if it is effective to control the rapid growth of vehicles in Beijing by using these limitations and the new car policy. As a result, the model shows that the limitation of cars in Beijing as well as the "Lottery" policy in Beijing is effective ways to help slow down the fast growth of cars in Beijing. Moreover, based on the model in this paper, five suggestions to improve transport problems were given.
