Simulation of Passenger Flow and Train Dynamics in Mexico City Metro Line 4 Using a Cellular Automaton Model (05:00–01:00 Operation)

This dataset contains a high-resolution simulation video of Mexico City Metro Line 4 operations, generated using a cellular automaton model based on the Nagel–Schreckenberg (NaSch) framework. The model incorporates a physically consistent representation of the railway corridor, including spatially extended stations with a length of 150 meters and a total corridor length of 9513 meters.

The simulation reproduces bidirectional train circulation between the terminal stations Martín Carrera and Santa Anita over a full operational period from 05:00 to 01:00. Passenger demand is modeled using empirically calibrated daily station inflows combined with a normalized hourly demand distribution. Passenger arrivals follow a Poisson process, while boarding and alighting dynamics are governed by capacity constraints and an origin–destination (OD) matrix.

The video includes a dynamic visualization of:

• Train positions along the corridor in both directions

• Spatially extended station segments

• Passenger queues at each station

• Accumulated passenger arrivals

• Total onboard passenger load

Additionally, the simulation accounts for dwell times dependent on station demand, stochastic train dynamics, and realistic terminal turnaround operations.

This video is intended to support reproducibility and provide a visual interpretation of the system dynamics described in the associated research work. It can be used for validation, educational purposes, and further research on urban rail transport modeling.
