![]() ![]() They observed the pedestrian flows in both cases and analyzed the barrier's effectiveness by running 100 simulation experiments. In the simulation, the team considered two scenarios – with and without barriers. For this model, they also used the software’s 3D animation feature. And, for the subway trains, they used the AnyLogic Rail library – the library allowed them to accurately simulate the dimensions of individual cars, the exact locations of tracks and switches, and so on. To simulate pedestrian flows, they used the AnyLogic Pedestrian library. ![]() They considered two agents – pedestrians and trains. The research team built an agent-based simulation model of the Zocalo subway station in Mexico City. Simulation model of the Zocalo subway station without and with barriers This pedestrian flow simulation research supported the decision-making process of the Mexico City government with regards to the installation of physical barriers on a subway platform to prevent suicides. These barriers run the length of a platform, separating the platform from the tracks, and only have small openings to allow pedestrians on and off trains. Such accidents usually happen due to distraction, psychological problems or if a person is under the influence of alcohol or drugs.Ī possible solution to this problem is the installation of physical barriers. According to the local government, if a pedestrian on a platform crosses the yellow safety line, there is a high probability they will fall onto the tracks. In the last few years, there has been an increase in the number of accidents involving pedestrians in Mexico City subway. ![]()
