Taisei, TIER IV Win MLIT Autoflow Road Autonomous Logistics Trial
Tokyo – October 14, 2026 -- Taisei Corporation, TIER IV, Inc. and Taisei Rotec Corporation have been selected by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) for a FY2026 demonstration project to accelerate deployment of the Autoflow Road, a logistics system that moves cargo with unmanned, automated vehicles in purpose-built lanes.
Three autonomous vehicles will test core multi-vehicle maneuvers in tunnels
The trial will evaluate platooning, bidirectional driving, lane changes, merging and diverging, and obstacle avoidance in tunnel environments and other dedicated space. Three autonomous vehicles will run on straight and curved sections.
The project will verify following, stopping, passing oncoming vehicles, merging and diverging, obstacle avoidance and berth stopping accuracy. It will also measure the driving space widths required, defined as standard, intermediate and minimum.
