Research On Income Distribution Model Of Urban Rail Transit

With the development of urban metro traffic construction in our country, the coupling degree of lines becomes high. The transferring among different lines becomes frequent. It is more difficult to make a perfect income distribution, because the scale of urban rail transit system is expanding constantly and the transfer path is not only. Therefore, the creation of a model of the income distribution to ensure the fair division is very important in the development of the urban metro traffic in our country.The artificial account division, ideal income distribution model and shortest path income distribute model are existing. These models do not satisfy the development of metro traffic constructions. A new division model is proposed after deep research on Beijing'smetro traffic is presented. It keeps the balance between impartiality and practicability.Based on the analysis of Beijing Urban Rail Transit, this article analyses the main factors that influent ticket revenue settlement and passenger's route selection. On the ground of the questionnaire of these main factors, this article gives a new idea of calculating the probability of passenger's route selection and the distributive proportions of available routes. The key idea is to get settlement ratio of each line by calculating distributive proportions of every routes and those of lines, and then to settle accounts for ticket revenue of each line. At last, this article takes Beijing Urban Rail Transit as example to explain and verify the double-proportion algorithm.In this algorithm, the stops and time of the transferred path are used as the main influence factors when passengers select a transferred path. Then the mathematical model of the income distribution by the above path searching algorithm is given. This research work meets the demand of settling account for each line during the rapid development period of Beijing Urban Rail Transit. It also enriches the theoretical research of settlement method, and can be a useful reference to the settlement of ticket revenue in urban rail transit.
