Abstract: Aiming at the low efficiency of taxi operation and management in railway passenger transport hub, the optimization model of the number of taxi operation lane was studied. Firstly, the problem of taxi operation organization in railway passenger transport hub was analyzed, and was abstracted into M/M/C queuing system to obtain the steady state index of the system. Then, the number of service desks in system was taken as a decision variable, the traffic mode choice model of railway passenger transport hub was taken as a constraint, and the optimization model of the number of taxi operation lane in railway passenger transport hub was established, with the goal of minimizing the sum of system operating costs and waiting costs of passengers. Finally, an example was given. The research results show that: the scheme obtained by the proposed model can make the comprehensive cost minimum and the service level higher than the actual situation; the feasibility of the proposed model is verified, which has important theoretical value for improving the operation efficiency of railway passenger transport hub and the service quality of taxi system.
