With the increasing scale of urban subway, total energy consumption subway has increased dramatically and poses a great challenge to comfort passengers punctuality train operation. In order ensure on-time operation passenger comfort, at same time reduce operation, this paper proposes Proximal Policy Optimization (PPO)-based optimization algorithm for optimal control Firstly, reinforcement learn...

This research aimed investigate Subway's 4ps (Product, Promotion, Place, and Price) marketing approach in the Chinese market intense rivalry business China, also revealed reason why Subway less competitive China other than U.S. Europe. must continue strive improved performance strengthen custom...

Robustness studies on integrated urban public transport networks have attracted growing attention in recent years due to the significant influence overall performance of system. In this paper, topological properties and robustness a bus–subway coupled network Beijing, composed both bus subway as well their interactions, are analyzed. Three new models depicting cascading failure processes propos...

Abstract. Urban rainstorms and floods often occur, causing serious loss of life property, bringing great challenges to the safe operation subways. In response need for prevention control urban subway waterlogging, this project is based on geographic information technology, basis "one map" subway, using intelligent sensing camera equipment, independent research development monitoring water level...
