- Autonomous Truck technology achieved Japan's first autonomous toll gate passage.
- LiDAR and sensor fusion enabled precise navigation through ETC lanes.
Japan has reached an important milestone in autonomous logistics as T2 Inc., an autonomous truck developer headquartered in Tokyo's Chiyoda Ward, announced on June 15 that it had successfully conducted field testing of Level 2 autonomous trucks navigating expressway toll gates without driver intervention. The achievement marks the first instance of an autonomous truck passing through a toll gate in the country, highlighting continued advancements in advanced driver assistance technologies for freight transportation and highway automation.
The demonstration was carried out at the Tomei Expressway Ayase Smart Interchange in Ayase City, Kanagawa Prefecture, and the Chugoku Expressway Nishinomiya Kita Interchange in Nishinomiya City, Hyogo Prefecture. During the tests, the autonomous vehicle completed a continuous sequence of operations independently, including entering the toll area, navigating through the gate, and exiting the toll zone. The successful operation demonstrates the feasibility of deploying automated trucking systems in real-world highway environments where toll infrastructure remains a key operational challenge.
To enable highly accurate vehicle localization, the company utilized pre-generated high-precision three-dimensional point cloud maps. The system compared these maps with real-time environmental information captured by LiDAR sensors mounted on the truck. By matching live sensor data against the stored maps, the vehicle achieved centimeter-level self-position estimation, enabling precise lane positioning and navigation in complex toll gate environments where accuracy is critical for safe operation.
Additional sensors were integrated to determine the operational state of electronic toll collection barriers. The system continuously monitored whether the ETC bar was open or closed, allowing the truck to safely initiate movement through the toll gate. Through the coordinated use of LiDAR and multiple sensing technologies, the vehicle autonomously completed all required driving functions from toll entry to departure, demonstrating the maturity of advanced driver assistance capabilities for commercial transportation applications.
Frequently Asked Questions
What makes T2 Inc.'s autonomous truck test significant?
The demonstration represents the first successful autonomous truck passage through an expressway toll gate in Japan, marking a key milestone for commercial autonomous driving deployment. The achievement validates the ability of autonomous trucks to handle complex toll infrastructure using Level 2 driver assistance technologies. By combining high-precision mapping, LiDAR sensing, and barrier detection systems, the company demonstrated that autonomous freight vehicles can perform real-world highway operations with high levels of accuracy and safety.
How did the autonomous truck navigate through the toll gate?
The truck used high-precision 3D point cloud maps together with real-time LiDAR data to determine its exact position with centimeter-level accuracy. Multiple sensors also monitored the status of the electronic toll collection barrier to determine whether it was open or closed. Using these technologies in combination, the vehicle autonomously executed all operations, including entering the toll lane, passing through the gate, and exiting the toll area without manual intervention.
