A multi-user simulator for safe emergency evacuation training

An interactive 3D emergency evacuation simulator for a US construction company, so staff in a new five-story building rehearse fire, gas, and disaster response together, with behavioral data to improve building safety.

Overview

Program-Ace built an interactive, multi-user 3D evacuation simulator so staff in a new five-story building could rehearse emergencies together safely, while the client gathered behavioral data to improve the safety design of the building.

The challenge

Staff moving into a new five-story building had never rehearsed an emergency there, and real drills are disruptive, hard to repeat, and cannot safely reproduce a fire or gas leak. The client also wanted hard data on how people behave under pressure, to improve the safety design of the building.

The solution

Program-Ace built a cooperative, multi-user 3D evacuation simulator that doubles as a behavioral-data tool.

Multiple emergencies: fire, gas leak, smoke, earthquake, tornado, and flood.
Cooperative team play with voice communication and bot-supported scenarios.
Health indicators and interactive objects that raise the pressure realistically.
A centralized rating system and statistics dashboard.
A customizable architecture for deployment across the other buildings in the client portfolio.
Technology and approach

How we built it

The simulator runs on the Ace3D engine with a LAMP back end for multi-user sessions and analytics, built in C and PHP with Visual Studio and the Windows SDK, rendered through OpenGL, and backed by Microsoft SQL Server. Trainees join as a group, communicate by voice, and work through scenarios with bot support, while every session feeds a centralized rating and statistics dashboard so the client can refine evacuation routes.

Results and value delivered

The simulator made evacuation training safe and repeatable, and turned each session into data the client could act on.

Repeatable, multi-scenario evacuation practice with no real-world risk.
Cooperative, voice-enabled drills that mirror real group behavior.
Behavioral data that helped optimize evacuation routes.
A reusable architecture deployed across multiple facilities.
