Summary
The social implementation of Level 4 autonomous driving (hereinafter referred to as L4) for commercial vehicles is being accelerated, with a target deployment date of 2027, to address the immediate issue of stagnation in logistics and human transportation. For this reason, external support is being received from various sectors, not only for technology development but also for infrastructure construction and the provision of evaluation facilities.
This report outlines the current state of external support, primarily from the public, as well as the latest technologies, notably L4 commercial vehicles that have been in demonstration / commercial operation services since the beginning of this year.
| To support the development of autonomous vehicles, JARI is enhancing the capabilities of its Special Environment Proving Ground (see photo). On-road testing under hazardous weather conditions is possible within the 200-meter-long track, which is already being used by startups to test heavy-duty trucks. | Many L4 test operations of trucks and buses have been attempted in various locations. In particular, priority road testing of trucks has been conducted on the Shin-Tomei Expressway, while L4 commercial operation of buses has been conducted on Hitachi City's bus routes (photo). |
