Tests have started on a new driverless bus system which could pave the way for an evening public transport service.
The RDM Group is using self-driving pods along the guided busway in Cambridge to test the feasibility of running 10-seater shuttles along the route.
If successful, the buses will run between Trumpington Park and Ride and Cambridge Station after 20:00.
The Greater Cambridge Partnership said it could meet the demand for services.
The feasibility study will deliver its findings in June 2018, the RDM Group said.
It said the £5m scheme to bring a fleet of buses could start soon afterwards.
Richard Fairchild, from the RDM Group, said the Trumpington to Cambridge guided busway was an “ideal route” for the driverless vehicles.
