minibus begins operation in Tokyo for the first time
On June 18th, a Level 4 self-driving minibus commenced operations in Tokyo. This driverless bus operates without a driver under specific conditions, such as predefined routes and speeds. It received permission from the Tokyo Metropolitan Public Safety Commission and is currently operating within the grounds of a complex facility near Haneda Airport. The 10-seater minibus travels at a speed of less than 12 kilometers per hour, with a tour guide on board, covering a distance of approximately 800 meters. After further testing and inspections, the plan is to allow the general public to ride the bus starting next month. The company responsible for operating the bus has previously run Level 2 minibuses with drivers in 17 locations nationwide and is gradually transitioning to Level 4 autonomy

Level 4 autonomy レベル4の自動運転
■上級向けAI解説
Level 4 autonomy is a significant step towards fully autonomous vehicles, but it still has limitations compared to Level 5, which aims for complete autonomy in all conditions.
Level 4 autonomy, also known as “high driving automation,” refers to vehicles that can operate fully autonomously in specific conditions without human intervention. Here are some key points about Level 4 autonomy:
Full Autonomy in Specific Areas: Level 4 vehicles can handle all driving tasks within a defined operational design domain (ODD), such as certain geographic areas or specific types of roads.
No Human Intervention Needed: Unlike Level 3, where a human driver must take over if the system requests, Level 4 vehicles do not require human intervention in most situations
Geofencing: These vehicles often use geofencing to limit their operation to specific areas where they can safely navigate
Safety Measures: If the system encounters a problem, it can bring the vehicle to a safe stop without human input.
Level 4 autonomy is a significant step towards fully autonomous vehicles, but it still has limitations compared to Level 5, which aims for complete autonomy in all conditions.

レベル4の自動運転は完全自動運転車への重要な一歩ですが、すべての条件で完全な自律を目指すレベル5と比べると、まだ制限があります。
レベル4の自動運転、別名「高度運転自動化」は、特定の条件下で人間の介入なしに完全に自律的に運転できる車両を指します。以下はレベル4の自動運転に関する主なポイントです:
特定エリアでの完全自動運転:レベル4の車両は、特定の地理的エリアや特定の種類の道路など、定義された運用設計領域(ODD)内であれば、すべての運転タスクを処理できます。
人間の介入不要:システムが要求した場合に人間のドライバーが引き継ぐ必要があるレベル3とは異なり、レベル4の車両はほとんどの状況で人間の介入を必要としません。
ジオフェンシング:これらの車両は、特定のエリア内で安全にナビゲートできるように、ジオフェンシングを使用することがよくあります。
安全対策:システムが問題に遭遇した場合、人間の入力なしで車両を安全に停止させることができます。
レベル4の自動運転は完全自動運転車への重要な一歩ですが、すべての条件で完全な自律を目指すレベル5と比べると、まだ制限があります。
