Dec 15 (Reuters) - Aurora Innovation Inc (AUR.O) on Wednesday said it had launched a pilot program with the freight unit of Uber Technologies Inc (UBER.N) to transport goods in Texas and to integrate autonomous trucking into Uber Freight"s shipping platform. Aurora said it began autonomously transporting loads for Uber Freight customers between Dallas and Houston last week. The company plans to launch its commercial autonomous trucking business by the end of 2023, starting in Texas. read more Uber is an investor in Aurora after the self-driving company bought Uber"s autonomous vehicle unit ATG last year and Uber acquired a 26% ownership interest in Aurora. Uber Freight is a platform that acts as a middleman in connecting shippers who need goods hauled with available truck drivers, oftentimes independent contractors in a highly fragmented market. An Aurora spokesperson said prior to last week"s launch, the company began collaborating with Uber Freight a year ago, hauling goods over thousands of miles in Texas to gain insight. Aurora said carriers who subscribe to its self-driving product will be able to book autonomous trucks through the Uber Freight platform once commercial self-driving trucks launch in 2023. Using autonomous trucks, carriers will be able to increase utilization of the truck and haul more goods more often between terminals, Aurora said. Human truck drivers are not allowed to drive more than 11 hours per day - restrictions that do not apply to self-driving trucks. The pilot program deploys so-called drop-and-hook loads, an industry term that describes a driver dropping off a full container at a terminal and then immediately grabbing a new one, without waiting for it to be unloaded. Human-operated trucks booked through the Uber Freight network then handle the last mile to the actual destination, where the goods are being unloaded, the companies said.
