Specific use cases - Hitachiota City

Operation support for autonomous driving electric buses

Hitachiota City has launched a service that provides bus operation status and city guidance through an AI concierge generated inside a autonomous driving electric bus that is in regular operation.
In addition to the cloud server, which serves as a general information source, information specific to Hitachiota City is imported into a local server, optimizing responses, preventing the risk of incorrect answers and providing a natural conversation experience in the car.
It has been well received and is used by many people, from children to adults.

Linking with remote operation management systems

Hitachiota City is linking its own remote operation management system, "everfleet," with the "Generative AI Concierge."
Bus operation information is recognized in real time and information is provided at the appropriate time.
In addition to audio, information is also displayed on the screen so that passengers can visually understand the operation status, supporting a safe and secure riding experience that is considerate to passengers.

Data utilization

Conversation data on buses will be statistically analyzed while respecting privacy, and the quality of customer service, in-bus announcements, operation information, safety, and more will be continuously improved.
We will use the PDCA cycle to evolve our services, improve the riding experience, increase utilization rates, and enhance local transportation services.
