Research on the method of passenger flow distribution forecast in urban agglomeration based on the improved Gravity Model

Aim to improve the traditional gravity model,this paper explores a set of suitable for urban agglomeration passenger flow distribution forecast method. Firstly,this paper puts forward the concept of the industrial connection,and described the feasibility of introducing the industry related degree of passenger flow distribution model in urban agglomeration. Then it detailedly provides a method of industry related degree between the traffic area and improves the gravity distribution model,puts forward passenger flow distribution prediction method of urban agglomeration based on industry related degree. Taking a certain city group as an example,it forecasts and analyzes the the passenger flow distribution of the urban agglomeration,confirms the improved passenger flow distribution model is scientific and reasonable.
