T2 Achieves Milestone: First 500km Autonomy on Japanese Highway

A Historic Achievement in Autonomous Driving

In March 2026, T2, a pioneering technology company based in Chiyoda, Tokyo, demonstrated a groundbreaking achievement in the realm of autonomous driving by successfully completing a nearly 500km journey on the main highway connecting Kanto and Kansai regions. This milestone was significant as it marked Japan's first complete highway run without a single manual intervention from a driver, utilizing T2's Level 2 autonomous truck technology.

The completion of this 500km journey is a testament to T2’s commitment to advancing autonomous transportation. Looking ahead, T2 has set ambitious goals to roll out Level 4 autonomous truck services by 2027, which promises improved efficacy in freight transport. In preparation for this leap, the company engineered enhancements to ensure their autonomous trucks can handle real-world scenarios, including unexpected situations such as road construction and merging vehicles, without requiring driver intervention.

On the day of the historic completion, T2’s autonomous truck navigated the Tomei Expressway between Ayase Smart IC in Kanagawa and Kobe Nishi IC in Hyogo smoothly. This journey serves as a pivotal step toward achieving T2's goal of fully autonomous freight transport. The truck was designed to recognize and respond to various road conditions, including construction signs and merging vehicles, ensuring it could adapt while maintaining a safe driving speed.

Advanced Technology at Work

The technology employed during the journey includes several key features aimed at enhancing safety and efficiency:

- Rapid Recognition of Road Conditions: When faced with sudden lane closures due to construction, the truck’s onboard sensors quickly identified the signs and markers, allowing for timely lane changes.
- Adaptive Speed Control: The system accurately detected situations with temporary speed limits and adjusted the truck’s speed seamlessly.
- Yielding to Merging Vehicles: The truck is equipped to reduce speed and yield to merging traffic at interchanges, an essential safety feature for highway driving.
- Strengthened Stability on Slopes: Enhanced capabilities ensure smooth navigation even on inclines.

The successful navigation of these complexities speaks volumes about the advancements T2 is achieving in making autonomous transport a viable option.
