Summary
This report details the outcomes of Phase One of the CapMetro Automated Driving Systems (ADS) Yard Automation Research and Deployment (YARD) project, funded by the Federal Transit Administration. The study addressed the need for practical data on transit bus automation by evaluating the feasibility, benefits, and challenges of SAE Level 4 autonomous maneuvers within a real-world depot environment. The primary objectives were to test automated battery electric buses (BEBs) in routine yard operations, assess workforce impacts, share lessons learned with industry stakeholders, and determine the long-term viability of fleet-wide automation. The project was conducted at CapMetro’s North Operations bus depot in Austin, Texas, involving partners including WSP, Clever Devices, Texas A&M Transportation Institute (TTI), and Perrone Robotics, Inc. (PRI). The technical implementation involved retrofitting a New Flyer Xcelsior BEB with PRI’s ADS technology. The team executed two demonstrations: an initial educational demo using a cutaway vehicle and a final operational demo using the retrofitted bus. This second phase tested four specific use cases: automated bus wash navigation, precision parking, remote start/stop, and automated charging via an overhead pantograph. Concurrently, TTI conducted a workforce analysis using position interviews and site visits, while WSP performed a benefit-cost analysis (BCA) and capacity assessment. The results demonstrated the technical viability of the system, achieving a 94.97% test pass rate with an operator and a 100% pass rate without an operator during validation stages. The ADS-equipped bus successfully completed all maneuvers, including autonomous charging and bus wash navigation, with no documented sensor damage. The BCA projected a net present value of $114.1 million and a benefit-cost ratio of 3.25 over 23 years for a fleet of 104 automated buses, driven by operational, safety, and infrastructure savings. Capacity analysis suggested automation could increase yard capacity by up to 35% and reduce charger requirements by 25%. Workforce findings indicated that while roles like service island attendants might see reduced labor hours, new positions such as Yard Hostlers and Supervisors would be required to manage the automated fleet. The study concludes that automated bus yard operations are practically viable and offer substantial economic and operational benefits. The project successfully met its goals of improving safety, promoting American competitiveness, and providing data-driven insights into workforce development. These findings support the Federal Transit Administration’s Strategic Transit Automation Research Plan and provide a foundational framework for future deployments, highlighting the importance of standardized testing protocols and the integration of automation into existing transit infrastructure.
Key finding
The deployment of SAE Level 4 automated driving systems in a transit bus depot demonstrated technical viability with high test pass rates and projected substantial long-term economic benefits, including a benefit-cost ratio of 3.25 over 23 years.
