Simulating the Effects of Gate Machines on Crowd Traffic Based on the Modified Social Force Model
Mathematics, 2023 Gate machines, such as ticket gates in stations and secure gates in office buildings, are very common in people’s daily lives. On the one hand, the passage between the gates is not wide enough for pedestrians to pass through, which may affect the traffic
