Driverless Buses: The race to develop autonomous vehicle technology has taken an exciting turn, with companies shifting their focus from robotaxis to driverless buses. As cities face an impending shortage of qualified bus drivers and grapple with the inefficiencies of robotaxis, autonomous buses are emerging as a practical and sustainable solution. These vehicles, equipped with Level 3 autonomy, are already making waves in public transportation, offering a glimpse into the future of urban mobility.
Unlike robotaxis, which have been criticized for contributing to traffic congestion, driverless buses are designed to improve urban efficiency. Kevin DeGood, director of infrastructure policy at the Center for American Progress, highlights the stark difference between the two modes of transport. “Buses and rail reduce congestion, while robotaxis increase it,” he explains. This is primarily due to the phenomenon of “deadheading,” where ride-hailing vehicles return without passengers, a problem that buses largely avoid. With the ability to carry dozens of passengers during peak hours, autonomous buses are poised to revolutionize public transit systems.
Currently, self-driving bus trials are being conducted on private campuses like universities and medical centers, where traffic is minimal and speeds are low. These trials focus on Level 3 autonomy, which requires occasional human intervention. However, the next milestone is Level 4 autonomy, where buses can navigate public roads without human input. Leading this charge is San Jose–based Imagry, a company that develops autonomous driving software and retrofits standard electric buses with self-driving technology. Founded in 2015, Imagry initially specialized in computer vision but has since pivoted to become a key player in the autonomous bus market.

Driverless Buses FAQs
1. What is Level 3 autonomy, and how does it work in driverless buses?
Level 3 autonomy, also known as conditional automation, allows a vehicle to handle most driving tasks independently but requires human intervention in complex or unpredictable situations. In driverless buses, this means the bus can navigate predefined routes, stop at designated points, and manage traffic interactions on its own. However, a human operator may need to take control in scenarios like severe weather, road construction, or unexpected obstacles. This level of autonomy is a stepping stone toward fully autonomous (Level 4) buses, which will operate without any human input.
2. How do driverless buses reduce traffic congestion compared to robotaxis?
Driverless buses are designed to carry multiple passengers at once, often transporting dozens of people during peak hours. This reduces the number of vehicles on the road, easing traffic congestion. In contrast, robotaxis typically carry only one or two passengers and contribute to congestion through “deadheading,” where the vehicle travels without passengers to pick up the next rider. By eliminating deadheading and maximizing passenger capacity, driverless buses offer a more efficient and sustainable solution for urban mobility.
3. Are driverless buses safe for public use?
Yes, driverless buses are equipped with advanced safety features, including LiDAR, radar, cameras, and artificial intelligence systems. These technologies enable the bus to detect and respond to obstacles, pedestrians, and other vehicles in real time. Additionally, autonomous buses undergo rigorous testing in controlled environments before being deployed on public roads. While no system is entirely risk-free, the combination of advanced sensors, redundant systems, and continuous monitoring makes driverless buses a safe and reliable option for public transportation.
4. When will driverless buses be available for public use?
Driverless buses are currently in the trial phase, operating on private campuses like universities and medical centers where traffic is light and speeds are low. These trials focus on Level 3 autonomy, with plans to transition to Level 4 autonomy in the near future. A full public rollout is expected by 2025, pending advancements in technology and regulatory approvals. Cities with progressive transportation policies and infrastructure are likely to be the first to adopt this technology.
5. How much does a driverless bus cost, and is it worth the investment?
The cost of a driverless bus ranges from $500,000 to $1,000,000, depending on the level of customization and additional features. While the initial investment is significant, the long-term benefits make it a worthwhile option for municipal transit agencies. Driverless buses eliminate the need for human drivers, reducing labor costs over time. They also operate more efficiently, lowering fuel and maintenance expenses. Additionally, their ability to reduce traffic congestion and emissions aligns with sustainability goals, making them a valuable investment for cities.
6. What makes Imagry a leader in autonomous bus technology?
Imagry, a San Jose–based company, has established itself as a leader in autonomous bus technology by developing cutting-edge software and retrofitting standard electric buses with self-driving capabilities.
