Abstract: Transitional passageway connecting subway stations and commercial facilities is generally designed as the multifunctional passageway, in which the traffic function is the main and the service function is the auxiliary. The impact of the service facilities on both sides of the passage on pedestrian traffic is difficult to be quantitatively analyzed and simulated and modeled. Through measurement, it is found that the viscous effect of service facilities on pedestrian traffic is mainly slowing down the speed or changing the trajectory direction. Through analyzing the horizontal influence range of service facilities, dividing the passage into different areas, and introducing the viscosity to describe the impact of service facilities, the social force model is improving. The simulation model is used to study the width setting of the multifunctional passageway composed of different pedestrians under the same facility layout and same design flow, and the recommended value of the passage width under the condition of different types of pedestrian proportions is obtained, which provides theoretical and methodological support for the design of this type of passage.
