Uber is putting its autonomous vehicles back on Pittsburgh’s city streets, four months after a fatal accident involving one of its self-driving cars prompted the ride-hailing company to halt testing on public roads. But for now, Uber’s modified self-driving Volvo XC90 vehicles will only be driven manually by humans and under a new set of safety standards that includes real-time monitoring of its test drivers and efforts to beef up simulation. 

The sensors, including light detection and ranging radar known as LiDAR, will be operational on these self-driving vehicles. They won’t be operated in autonomous mode, however. Uber will use these manually operated self-driving vehicles to update its HD maps of Pittsburgh.
