Automated operation device lets a Hitachi BRT bus run with no driver

On 26 November 2024 a Japanese transport bureau confirmed that a Hitachi BRT bus's automated operation device met the safety standards. It approved the bus as a Level 4 vehicle on about 6.1 km.

  • Not rated society

    The bureau approved the bus for service with no driver on a conformity check, and no outcome for riders or other road users is reported.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

An independent regulatory document supports the benefit.

Size

None: the benefit is not shown to have happened.

The system’s part
Not isolated. The bureau confirmed that the device met the safety standards and gives no comparison with a human driver. The release describes sensors that locate the bus and the detection of vehicles and pedestrians. The maker's 2025 presentation names AI in obstacle avoidance control, and no source shows that the device on this bus learns from data.
Learns from data

Not shown. Advanced Smart Mobility's presentation of 2 October 2025 lists AI and high-precision maps under obstacle avoidance control in its automated bus configuration, and a Hokkaido Regional Development Bureau document on the company's 2017 test bus describes deep learning image recognition of vehicles and pedestrians. No source shows that the device on the Hitachi BRT bus learns from data.

Details

AI system

Workflow

The bus finds its own position with sensors and follows a set route of about 6.1 km on the BRT's dedicated road at up to 40 km/h. It detects surrounding vehicles and pedestrians while it drives. The bureau confirmed that the automated operation device met the safety standards and set its operating environment conditions.

Follow-up

Conditions for replication

The bus drives itself only on the approved section and under the conditions of the approval. Level 4 service also needed a permit from the Ibaraki Prefectural Public Safety Commission, which Ibaraki Kotsu reports that it received on 18 December 2024.

Entry details

Sector

Road vehicle automated driving.

Purpose

Advanced Smart Mobility built the automated operation device to drive the bus on a set route with no driver under specific conditions.
