Passengers mining big data to keep Metro safe

RESIDENTS now can become volunteer security guards on the Metro and report bad behavior or anything suspicious they see via mobile app “Metro Daduhui.”

The app is part of a big data system that Shentong Metro Group has been working on for years. The system helps the Metro operator better understand the needs of its users and improve its services.

On the Shentong stand at the World Artificial Intelligence Conference’s smart city zone, a screen shows how the big data platform works with real-time data on Metro lines and trains, including details of congestion and the distribution of workers and volunteers.

On another page, all Metro trains are listed on the screen. When you click on a train, you can see its real-time condition and the state of its facilities, such as the air-conditioning system, for example.

“Metro Daduhui” is no longer just an app just for buying tickets or getting information. According to Shentong’s Liao Zhigang passengers can use it to report security hazards and inappropriate behavior. They can also help Metro officers to identify illegal items and suspicious people.

Liao said the system can also give advice if an emergency should occur.

The local power supply company also brought their latest big data tools to the expo.

The State Grid platform can monitor the electricity consumption of organizations and individuals in real time. It can detect the areas and companies with the highest consumption of electricity and adjust distribution.
