A novel research on the relation between the number of passengers and the braking distance of a metro

Abstract

This paper on the relation between the number of passengers and the braking distance of a metro is from the proceedings of the 12th International Conference on Computer System Design and Operation in Railways and Other Transit Systems, held in Beijing, China, in 2010. The authors remind readers that, due to heavy traffic at peak times, it is necessary to ensure that trains have an absolute safety braking distance. To address this problem, the authors not only analyze various factors that influence a metro’s stopping time, but also analyze a time model of a metro’s stopping in the station. Based on the model and combined with the physical process of a metro’s approach, they calculate the braking distance of oncoming trains. Finally, a novel relation between the number of passengers and the braking distance of an oncoming metro is established. The authors conclude through their theoretical analysis and simulation experiments that the braking distance of an oncoming metro can be effectively calculated according to the number of passengers on the platform.
