LifeSim is the life loss and direct damage estimation software used by the U.S. Army Corps of Engineers. LifeSim is designed to simulate the entire
warning and evacuation process for estimating potential life loss and direct economic damages resulting from floods. The following is a description of
the major capabilities of LifeSim:

- Graphical User Interface
- Agent Based Modeling
- Uncertainty
- Graphics and Reporting

The user interacts with LifeSim through a graphical user interface (GUI). The interface is designed to make it easy to use the software, while still
maintaining a high level of efficiency for the user.

LifeSim uses an agent-based approach to track individuals throughout the warning and evacuation process. During an evacuation, agents are interacting
with the roads, other vehicles, and the incoming hazard. After the warning and evacuation process has been simulated, LifeSim calculates lethality for
those people who are exposed to the hazard and the associated direct damages. By tracking individual people and their movements, LifeSim can help
identify where people are most at risk of losing their lives, whether it is on roads or in structures.

Three modes of evacuation are included in LifeSim: cars, sports utility vehicles (SUVs), and pedestrians. For vehicular evacuation, a dual regime
modified Greenshields model (USDOT) in conjunction with spillback enforcement is used for traffic propagation to represent the effects of traffic
density and road capacity on vehicle speed. Each road is assigned default values for the number of lanes, free flow speed, traffic jam densities, and
minimum stop-and-go speeds based on the Highway Capacity Manual (HCM) (TRB 2000).

To define the routes people use to evacuate, a road network is provided where each segment of the network contains information such as road category,
directionality, ground offset (for bridges), and interconnectivity. The road network can be imported from an existing GIS polyline shapefile or from
OpenStreetMap. OpenStreetMap is a collaborative project to create a free editable map of the world. During each timestep at the user defined interval
Δt, evacuating groups (PAR evacuating from a structure in a single vehicle) move as far as the model allows until the group reaches a destination
point, gets caught, or becomes stranded. More information on the evacuation simulation can be found in the (RMC 2021).

LifeSim applies both natural variability and knowledge uncertainty through Monte Carlo analysis. Multiple parameters can be entered with uncertainty
including those that influence the warning and evacuation timeline. Each iteration in a simulation represents a scenario that could occur given the
data uncertainties in the model. The results of the analysis provide a distribution of estimated consequences from a given hazard.

<CitationFootnote />
The idea for the LifeSim Applications Guide stemmed from the need to provide additional assistance and examples to the consequences field of practice. The User’s
Guide and Technical Reference Manual provide some detailed information on how to use LifeSim. The Applications Guide walks through several real-life dam projects
and studies, and details how the LifeSim model was conducted and why. Some applications focus on using LifeSim to support dam and levee safety risk assessments;
other applications walk through Flood Risk Management (FRM) and Coastal Storm Risk Management (CSRM) studies and how LifeSim was used to support plan formulation
and decision-making.

For additional information on LifeSim, please refer to the <Link to="/docs/desktop-applications/lifesim/users-guide/v1.0/preface">LifeSim User's Guide</Link>
and <Link to="/docs/desktop-applications/lifesim/technical-reference-manual/v1.0/preface">LifeSim Technical Reference Manual</Link>. The Applications Guide is not
intended to be a stand-alone document, and it is recommended that users have a basic understanding of LifeSim and/or consequence estimation before using this guide.
This guide is not intended to provide a comprehensive overview of all LifeSim features and capabilities, but rather to highlight how LifeSim can be used to support
various types of studies and analyses.
