Current lighting control methods for urban rail transit platforms suffer from simplistic control mechanisms and low accuracy, leading to significant energy waste and failure to provide passengers with a comfortable lighting environment. Based on the characteristics of passenger flow, zonal functional features, and psychological needs of passengers, this paper proposes an energyefficient lighting control method for urban rail transit platforms using passenger density as the primary parameter. The method first establishes a functional relationship between passenger density in different zones and time periods and the required illuminance levels by analyzing the spatial characteristics of platforms and temporal variations in passenger psychology. Subsequently, a linear programming optimization model is developed with the goal of minimizing platform lighting energy consumption, subject to illuminance requirements, using luminaire dimming coefficients as control variables. The model is solved using the simplex method, and case studies are conducted. The results show that in lowpassengerflow stations, compared to conventional control methods, the proposed method reduces platform lighting energy consumption by 27.68%, 38.16%, and 38.87% during morning peak, evening peak, and offpeak periods, respectively, while maintaining illuminance levels within the appropriate range. This method effectively reduces energy consumption and enhances the lighting comfort of urban rail transit platforms.
