Workers at Sydney's Olympic Park will be among the first to use a driverless shuttle bus as part of a two-year trial of autonomous vehicles launched by the state government.

The first stage of the trial starting later this month will involve tests and safety checks of the shuttle bus in an off-road environment at Newington Armoury near the former Olympic village. The vehicle will run autonomously on a pre-programmed route.

The trial will be extended next year to roads at Sydney Olympic Park where office workers and other members of the public will get a chance to ride the driverless vehicle.

Transport Minister Andrew Constance said the trial would showcase the government's bigger vision for a technology-enabled transport future in NSW.
