The Optimization Method For Configuration Of Automatic Fare Collection System In Subway Station With Consideration Of Dynamic Passenger Flow

At present,the urban rail transit in China is devoloping rapidly,and many cities are in the climax of planning and construction.The rational design of the internal service facilities of the subway station directly affects the user experience of passengers,the efficiency and safety of station collection and distribution.It is of great significance for the construction and operation of the subway station to discribe the passenger flow reaching regulation of the subway station and optimize the number of Automatic F are Collection System.In the previous studies,the average arrival rate of passenger flow at peak hours was only considered.However,the arrival rate of passenger flow in different periods varied greatly with time.And results show that comparing with ordinary steady-state model,the Queuing Model with consideration of dynamic passenger flow can reflect the different passenger queues with the different arrival rates of periods for AFC in subway station,which can reflect the operation of AFC for subway st ation objectively.In this paper,the dynamic changes of passenger flow are abstracted as Markov random environment,thereby establishing a queuing model under random environment.The relevant parameters of the model are calibrated,and the final queuing m odel of the ticket equipment for the subway station is established and its related performance indexes are derived.And it is popularized to the whole sale ticket queuing network through the transfer probability matrix of passenger flow.In the previous studies on the optimization of subway station facilities,only passenger safety and the economics of station operations were often considered,and there was a lack of consideration of passenger travel time costs.In this paper,the fixed cost,operation cost,maintenance cost and travel time cost of the railway station AFC are taken as the considerations,and the passenger safety index is taken as the constraint condition.Based on the performance indicators determined by queuing model of subway station AFC,the passenger travel time cost,equipment fixed cost and operation cost are characterized,and an optimization model with minimum cost as objective function is constructed...
