Solution by Gohji:

We developed a real-time simulation and digital twin of a major UK city district using Unreal Engine.

The platform allowed civil defence teams to:

Navigate realistic flood, fire, and chemical spill scenarios

Interact with simulated citizens, infrastructure, and emergency services

Receive performance feedback based on response time, decision-making, and resource use

Run multi-agency drills (fire, NHS, police) in a shared multiplayer environment

Sync with real GIS data and weather APIs to simulate future conditions

Outcome:

• 40% faster decision making in live drills

• Improved inter agency coordination

• Scalable to other cities and crisis types

• Now used as a national training benchmark
