TuSimple公司的两辆自动驾驶卡车将在亚利桑那州的凤凰城以及德克萨斯州的达拉斯这两座西南城市之间派送邮件。卡车将在两座城市往返5趟。每次往返路程约3300公里。
The testing is aimed at seeing whether the self-driving technology can reduce transportation times and costs and improve road safety. If successful, the Postal Service could deploy the trucks permanently to move mail between major U.S. population centers.
测试旨在了解自动驾驶技术能否缩短运输时间、降低成本，改善道路安全。如果测试成功，美国邮政局或将在主要人口中心城市之间永久性部署这类卡车派送邮件。
"The work with TuSimple is our first initiative in autonomous long-haul transportation," said Postal Service official Kim Frum. She told the Reuters news agency the project is part of USPS efforts "to operate a future class of vehicles" using the latest technologies.
美国邮政局官员金·弗拉姆（Kim Frum） 表示：“与TuSimple公司的合作是我们在自主长途运输方面的第一个项目。”她告诉路透社，该项目是美国邮政局采用最新技术“运营未来一类车辆”的一部分。
TuSimple said a human "safety driver" will be sitting in the driver's seat at all times during the trips to intervene if necessary. An engineer will ride in the passenger seat as an observer and to take notes.
