"If a trip requires travel on roads outside of One North, the safety driver will take control of the vehicle for that portion of the trip," a joint statement by Grab and software company nuTonomy said.
The partnership follows the 15 September launch of a groundbreaking driverless car service in the US city of Pittsburgh by Uber, the world's leading car-hailing company.
The trial will run for the next two months, and may be extended for as long as it continues to yield useful feedback and data that can feed into the roll-out of driverless taxis across Singapore in 2018. The announcement came three days after Singapore-based Grab said it had raised $750 million in funding from investors, taking its total capital to more than $1.0 billion, as it looks to expand in the lucrative Southeast Asian market and bolster its lead over Uber.
But Uber's launch of a driverless car service catapulted it ahead of Detroit auto giants and Silicon Valley rivals with technology that could revolutionise transportation. In an ambitious experiment, a fleet of cars laden with lasers, cameras and other sensors-- but with no hands on the wheel - were deployed on Pittsburgh's challenging roads, steering themselves to pick up passengers.
