Arizona: Police have released a short video of a fatal collision between an Uber self-driving vehicle and a pedestrian, as investigators probe the accident that has put new focus on the safety of autonomous vehicles.

The video, taken from inside the Volvo XC90 sport utility vehicle that Uber has used for testing, shows the vehicle driving along a dark road when an image of a woman walking a bicycle across the road appears in the headlights.

The woman, Elaine Herzberg, 49, later died from her injuries.

Police have released few details about the accident that occurred on Sunday night in Tempe, Arizona, a suburb of Phoenix, while the SUV was driving in autonomous mode. Uber suspended its self-driving testing in North America after the incident and federal safety regulators are conducting their own probe.

The video shows the vehicle travelling in the right-hand lane of a divided four- lane roadway. Suddenly, the vehicle's headlights illuminate a woman directly in front of it who is crossing the SUV's lane with her bike.
