The Moscow metro is looking to develop traffic lights to regulate the flow of passengers on escalators, the Moskva news agency reported Thursday.
Red and green lights will be used to convey instructions from escalator operators to passengers — directing them to stand on one or both sides of the escalator, says Nikolai Volosov, head of the Vidor company tasked with building the light prototype for the Moscow metro.
When such traffic lights will be incorporated and which stations will be equipped with them remains unclear.
