USPS tests autonomous semi-trailers for long-haul mail logistics

The two-week pilot with program with TuSimple – staged on one of the country’s significant trucking corridors – may be a decisive case study for the operational efficiency of autonomous logistics.

The United States Postal Service (USPS) has partnered with San Diego-based TuSimple, Inc. to test the feasibility of using self-driving trucks to haul mail-laden USPS trailers across long distances. TuSimple, which specializes in autonomous trucks, will perform five round trips between USPS distribution centers in Phoenix and Dallas over the course of a two-week pilot program. USPS will use the program to assess factors like fuel cost reduction, operational safety, and fleet utilization rates.

The Class-8 vehicles – or semi-trailer trucks – will cover more than 1,000 miles over the course of the five 22-hour trips, travelling along the I-10, 1-20, and I-30 interstate corridors through Arizona, New Mexico, and Texas. Each truck will have a safety engineer on board at all times to monitor vehicle performance and to ensure public safety.

 

 

Long-haul routes with short turnaround times are normally accomplished with two-member driving teams. Companies often face recruitment challenges when hiring long haul teams due to overnight driving requirements, the need to share close quarters with another person, and a significant shortage of qualified truck drivers – with an estimated workforce deficit of 175,000 drivers by 2024 according to the American Trucking Association (ATA).

With driverless long-haul operations, companies like TuSimple could potentially free human drivers to focus on shorter, more dynamic, and closer-to-home routes. The company’s trucks are the first in the industry to be able to navigate autonomously from depot to depot, whereas most other self-driving trucks are limited to highway-only autonomous operation.
