The NSW government is resisting calls to mandate masks on public transport and instead is rolling out a new app to warn commuters when their train is too crowded. This "world first" will be important as people return to the office.
The Opal Travel app will use real-time data from registered Opal cards and loading patterns on Sydney trains to predict whether a commuter's usual train service is too crowded, and whether physical distancing will be breached.
A push notification will then be sent to the traveller's phone, on an opt-in basis.
