    Abstract
  • Subway footway and passenger flux were described as a queuing system at rush hours, a queuing optimization model was built based on the analysis of parameter characteristics, and a new approach for determining subway footway width was developed by combining the level of service for passengers with the calculation of subway footway capacity.A simulation model was proposed to testify the theoretical model above, which was capable of simulating the queuing system with any arrival process and any distribution of service time.Comparison result shows that the results of queuing optimization model and stochastic simulation at the lowest level of service are both close to the values of existing design norm, but with the improvement of service level, the values calculated by the former two methods show a remarkable trend of simultaneous growth, while those derived from the existing design norm show a level trend.
