Beijing has taken measures to improve transport safety management through the use of digital technology, giving drivers 1,800 wristband sensors for the real-time monitoring of vital signs and mental stress.

Beijing Public Transport Group, the capital’s main bus operator, recently equipped drivers — particularly those driving on highways or on long cross-provincial trips — with the monitors in an effort to raise safety.

In cooperation with professional institutions, the group has tested more than 40,000 drivers for psychological suitability, with a second round of driver compatibility testing already completed.

With a population of over 21 million, Beijing’s motor vehicle ownership, congestion and traffic intensity have all increased rapidly in recent years.

As a result, accidents involving buses, as well as the driving safety of drivers, have drawn increasing attention.

“The emotion-sensing equipment is part of efforts to improve driving safety, which demonstrates care for drivers,” said Wu Ruidong, a news commentator.
