The waiting hall is an important part for railway passenger station. To optimize and analyze the usage of waiting hall has great significance for improving operation efficiency of railway passenger station. Based on the research on the passenger volume and passenger flow construction, distribution regularities of passenger arrival time, passenger waiting time and the capacity of checking tickets windows can be obtained. By analyzing the distribution function of the above regularities, methods of calculating the efficient time of passengers occupying waiting halls can be achieved, so is the minimum departure time interval for trains in the same waiting area. On the basis of optimization and analysis of large scale railway passenger stations, algorithm for passenger stream lines of different platforms can be obtained and 0-1 planning model of the minimum waiting areas divided can be established. Based on the above work, constrains on whether there exist parallel operations for railway staffs are established,
