Yelloz says that introducing driverless operation without passengers on board trains would enable metro operators to automate such things parking trains, turning trains round at terminals, waking up trains at the start of service and depot operations such as cleaning trains. He also says recovery after disruptions would be faster than with conventional manual operation.
 
"Some metro operators want to upgrade their system but are not ready to go to full driverless operation," Yelloz told IRJ in Paris. "This would be a first step to upgrading to full driverless operation with passengers on board in the future."
