Towards Better Railway Service: Passengers Counting in Railway Compartment

Counting passengers in railway compartments is an essential problem for improving service quality, user experience, public security, and disaster relief in the railway system. Considering many limitations in the compartment, the infrared sensor, 3D camera, etc. are not practical in this scene. Due to the flexibility and lower cost, solutions with standard cameras attract much attention in real applications. However, since the problem with scale variation in the narrow space is different from universal detection or counting problems, the specific benchmark of dataset and methods should be provided and proposed for this task. In this paper, we provide a passenger counting dataset. Relying on this dataset, we propose a passenger counting method. The solution contains a motion supervised multi-scale representation method which provides proposals against scale variation, a spatially-temporally enhanced counting which provides precise counting numbers, and a partial proposal method which conducts methods to be utilized in reality. With the proposed solution, the passengers counting task is solved in higher accuracy and practicable in the compartment environment. In experiments, the results show that all the modules in our solution are useful and efficient, and our method outperforms in comparison with others in the compartment scene.
