Abstract:Compound corridors is the main component of large public buildings. In order to quantitatively describe the pedestrian traffic flow characteristic at compound corridors, and solve the pedestrian traffic problem in public buildings, the queue waiting for service at compound corridors was described as a queuing system, and a mathematical model to calculate the pedestrian flow rates was built based on the analysis of parameter characteristics. The pedestrian service level is evaluated combining with the HCM method and based on the investigation data obtained from Jiageng Stadium station in Xiamen and a university mess hall.
