Fujitsu’s digital twin-based traffic simulation system has been adopted for public transportation planning in Maebashi City, Japan. The system, developed under a project led by Japan’s Ministry of Land, Infrastructure, Transport and Tourism, provides data-driven support for reorganisation of bus routes.

The simulation platform utilises Fujitsu’s social digital twin technology to replicate human and social behaviour using statistical data on resident movement and passenger transit patterns from MaaS applications. It is the first system in Japan capable of simultaneously simulating fixed-route and demand-responsive transportation. The technology is intended to help municipalities address driver shortages and the needs of residents with limited mobility.

Fujitsu plans to commercialise the simulation system as a service by fiscal year 2026. The system simulates both fixed-route and demand-responsive transportation. It uses statistical data on resident movement and ridership obtainable from MaaS applications. The technology supports the pre-verification of urban transportation measures by simulating human and social behaviour.

The adoption of the system in Maebashi City follows its selection for the COMmmmONS regional transportation promotion project in April 2025. Fujitsu stated that the technology supports the pre-verification of transportation measures, contributing to carbon neutrality goals and the modernisation of regional public transportation systems.
