[email protected] a1111111111 a1111111111 Abstract a1111111111 a1111111111 Aimed at the complicated problems of attraction characteristics regarding passenger flow in a1111111111 urban rail transit network, the concept of the gravity field of passenger flow is proposed in this paper. We establish the computation methods of field strength and potential energy to reveal the potential attraction relationship among stations from the perspective of the collec- tion and distribution of passenger flow and the topology of network. As for the computation OPEN ACCESS methods of field strength, an optimum path concept is proposed to define betweenness cen- Citation: Li M, Wang Y, Jia L (2017) The modeling trality parameter. Regarding the computation of potential energy, Compound Simpson's of attraction characteristics regarding passenger Rule Formula is applied to get a solution to the function. Taking No. 10 Beijing Subway as a flow in urban rail transit network based on field theory.

Firstly, the bigger field strength value between two stations is, Editor: Xiaolei Ma, Beihang University, CHINA the stronger passenger flow attraction is, and the greater probability of the formation of the largest passenger flow of section is.
