A self-driving vehicle scheduled to carry passengers on a Madison street this week was sidelined after a crash with a delivery truck caused by a human error in Las Vegas.

Self-driving vehicle company Navya was supposed to demonstrate its driverless shuttle in Madison this week. But now passengers in Madison will have to wait until spring, said Peter Rafferty, a researcher in UW-Madison’s Traffic Operations and Safety Laboratory.

The minor crash occurred last week after the shuttle stopped when it sensed the truck backing up. But the truck continued backing up until it grazed the front of the shuttle, causing minor damage, the Las Vegas Review-Journal reported. The driver of the truck was cited.

While the shuttle was back in service the same day, it’s not allowed to operate until the National Transportation Safety Board completes an investigation, Rafferty said.

“While this is disappointing to us, it is a temporary setback,” he said. “Safely navigating ... is part of our mission, and this definitely includes operating in mixed environments with human-driven vehicles.”

But the vehicle has arrived in Madison for public viewing.

It will be displayed Wednesday at the State Capitol from 11 a.m. to 1 p.m., Friday at the UW-Madison College of Engineering between 9 a.m. and 3 p.m. and Saturday from 8 a.m. to 4 p.m. The display location and times for Thursday haven’t been determined.

The UW-Madison-led Wisconsin Automated Vehicle Proving Grounds — a collaboration of industry professionals, the state and the university that’s focused on autonomous vehicle research and testing — was designated earlier this year by the U.S. Department of Transportation as one of 10 groups to test self-driving vehicles.
