It can be used for following situations:

  • Non-Event Simulations or normal
  • Ingress/Egress (baseline)
  • Event driven evacuations or shelter-in-place
    simulations such as:
    • Event Evacuation
    • Bomb threat
    • Fire
    • Power
    • Natural disaster
    • Civil disturbance used
      Active shooter
    • Chemical-biological-radiological-nuclear
      -explosive (CBRNE) incident
    • Hot spots
    • Process evacuations

E-SIM can be used to model movement
from large areas such as:

  • Campuses
  • Fairs
  • Amusement parks
  • Expositions
  • Sports venues

from confined spaces such as:

  • Mass-transit systems
  • Ships
  • Observation Towers
  • Tunnels
  • Hospitals
  • Hotels

and can be used to evaluate:

  • Crowd movement
  • Reaction time
  • Evacuation strategy
  • Operational Processes
  • Manpower Utilization
  • Directed/self-directed evacuations
  • Number of required first responders
  • First responder training and expertise
  • Number of required ambulances/transport vehicles
  • Local medical personnel capability/expertise
    for treatment

E-SIM Visualization Capabilities:

  • Use custom sky and ground graphics
  • Fully explore the environment and structure(s)
  • First person controls for ease of movement
  • Zoom in for greater detail or out to see the
    bigger picture
  • Use the camcorder mode to create custom
    camera movements for video recording
  • Easy to use panning in all directions that allows continuous movement without having to constantly move the mouse
  • Lock the camera to any place in the
    environment to focus view

Agent (people)-based approach to modeling behavior:

  • Bases behavioral perspective on rules and
    artificial intelligence
  • Accounts for people-to-people interactions
    and people-to-environment interactions
  • Distinguishes between first responders and
    patrons and between children and adults
  • Accounts for impaired movement of
    handicapped individuals
  • Accounts for impaired movement and/or
    death of agents in affected areas based on localconditions and exposure
  • Assign individual agent characteristics or
    distribute characteristics across facility population

Showcased Projects:

  • Life safety design support for a U.S.
    Federal Courthouse
  • Evacuation analysis of a government office
    building subjected to an explosive attack
  • Evacuation analysis of three potential bottleneck locations for a major league baseball team
  • Human affects analysis for a chemical attack on a convention center and a museum



E-SIM Event Simulator software is a tool to realistically model the movement and interaction of people in multiple event scenarios.

E-SIM scenarios take in to account individual human behaviors through agent-based modeling.

The E-SIM simulation tool uses detailed two-dimensional (2-D) or three-dimensional (3-D) models of facilities to evaluate ingress/egress in emergencies and complex operations and processes. This tool enables users to determine the best routes, foreseeing potential obstructions, addressing the chaos/panic factor and orchestrating the evacuation.

ESIM Visualization Capabilities

E-SIM view showing only agents, floors and stairs with custom colors

Example E-SIM views

  • Showing first floor with walls
  • Showing three floors and walls
  • Stairwell with agents using all custom colors

E-SIM Videos

E-SIM Video This video shows the camcorder function of the E-SIM visualizer following a  pre-recorded path around the exterior and through the interior of a 3D model; a hotel in this instance. The camcorder allows the user to create a path for the camera to follow and then “replay” it with fluid motion, thereby removing the common, jerky movements of manually controlling a camera. The model in this video has little to no transparency in order to create a better sense of depth to the user.

E-SIM Video

This video shows a flyover of a 3D model of a stadium using the camcorder feature while a simulation is being displayed. The visualizer allows for the resultant data of a simulation to be displayed in 3D so that it is easier to understand; especially at glance. This simulation, in particular, shows the predicted/simulated movement of a crowd attempting to exit this building during an evacuation.


E-SIM Video

Threat Evacuation Simulation-Directed

This movie demonstrates the results of a sarin gas (a fast acting nerve agent) attack where people are directed to avoid the lobby

Threat Evacuation Simulation-Un-directed

This movie demonstrates the results of a sarin gas (a fast acting nerve agent) attack where people are told to exit the facility, but are given no additional directions. The modeled attack is located in the main lobby, where most people enter and exit the facility. The modeled individuals in the movies are color coded based on their chemical exposure/health:

Blue minimal exposure/Unaffected;
Green– minor exposure/limited health affects;
Yellow – moderate exposure/Incapacitated and needs assistance;
Red– severe exposure/ fatal.
