Software Description:
Pathfinder is an emergency egress simulatorthat includes an integrated user interface and animated 3D results.Pathfinder allows you to evaluate evacuation models more quicklyand produce more realistic graphics than with other simulators.
Robust Import Options
Pathfinder provides support for the import of AutoCAD format DXFand DWG files. Pathfinder’s floor extraction tool makes it possibleto quickly use the imported geometry to define the occupant walkingspace for the evacuation model. PyroSim or Fire Dynamics Simulator(FDS) models can also be used to extract the walking space.
If you have a blueprint, it can be imported in GIF, JPG, or PNGformat and then used as a background to help you rapidly draw yourmodel directly over the image.
Continuous Movement Mesh
Pathfinder uses a 3D triangulated mesh to represent the modelgeometry. As a result, Pathfinder can accurately representgeometric details and curves.
Triangulation also facilitates continuous movement of personsthroughout the model, compared to other simulators that subdividethe space into cells that can artificially constrain the movementof occupants.
Multiple Simulation Modes
Pathfinder supports two simulation modes. In Steering mode, agentsproceed independently to their goal, while avoiding other occupantsand obstacles. Door flow rates are not specified but result fromthe interaction of occupants with each other and with boundaries.In SFPE mode, agents use behaviors that follow SFPE guidelines,with density-dependent walking speeds and flow limits to doors.SFPE results provide a useful baseline for comparison with otherresults, but SFPE calculations do not prevent multiple personsoccupying the same space.
Optionally, Pathfinder allows you to specify door flow rates insteering mode to obtain superior visualization in a constrainedmodel. You can freely switch between modes in the Pathfinder userinterface.
Occupant Movement to Exits
By default, each occupant (agent) uses a combination of parametersto select their current path to an exit. The parameters include:queue times for each door of the current room, the time to travelto each door of the current room, the estimated time from each doorto the exit, and the distance already traveled in the room. Theagent responds dynamically to changing queues, dooropenings/closures, and changes in room speed constraints(simulating smoke and debris). The user can modify the defaultparameter weights to change the behavior. For example, occupantscan neglect queues and only look for the closest exit.
Alternately, occupants can be assigned specific goals (such as, goto a location and wait) or specific exits. For example, mostoccupants of lower floors can be assigned to use stairs, while mostoccupants of higher floors can be assigned to use elevators.
High-quality 3D Visualization
Pathfinder includes human models that represent a range ofcultures, ages, attire, and emergency responders. These make itpossible to realistically portray the population group of interest.Because we use a dynamic level-of-detail to display the models,Pathfinder can smoothly animate tens of thousands of people in realtime using a standard graphics card.
Pathfinder also provides easy tools to create movies that documentthe results.
Elevators
Pathfinder gives you the flexibility to evaluate evacuation optionsusing elevators. Each elevator has a priority list of pickup floorsand a discharge floor. People can move directly to the closestelevator or be directed to go to a refuge floor and wait untilevacuated by elevator. Emergency responders can control selectedelevators to carry them to desired locations.
A call to an elevator is initiated by a queue at the elevator door.Elevators can be grouped in banks to respond to calls.
Stairways, Escalators, Moving Walkways, andRamps
Stairways and ramps are created using simple mouse clicks onlandings. Optionally, stairways and ramps can be used to representescalators and moving walkways (sloped or flat).
Customizable Populations
Each person in the model acts as an agent with their own profile(such as size and walking speed) and their own behavior (such asexits, waits, and waypoints). Based on their characteristics, eachperson uses their local environment to make decisions on exitpaths. For example, people can dynamically avoid long queues orrespond to the closure of doors.
Multiple profiles can be created and assigned to differentpopulations. Parameters in each profile can be described usingconstant, uniform, standard normal, or log normal distributions.For example, profiles representing children and adults can becreated and then the population can be assigned to be 80% adult and20% children. Similarly, multiple different behaviors can becreated and assigned to populations. People may have different exitgoals and may proceed to waypoints or wait before proceeding.
Turnstiles and Other Flow Constraints
The flexibility provided by Pathfinder can be used to simulaterelatively complex flow situations. For example, by combining doorsthat have specified flow rates, way points, and wait times,Pathfinder can simulate queuing and proceeding throughturnstiles.
Emergency responders can be directed to proceed up a stairway(against the evacuation flow) to a specified location and waitbefore proceeding to another location.
Doors and room speed modifiers can be scripted to activate ordeactivate at prescribed times, simulating a changing environmentduring an evacuation.
Powerful Results Evaluation
Display of 3D results is available both during the calculation (toview current status) and immediately on completion. The 3D displayallows the user to interactively display occupant movement, runback and forward in time, view paths, and select people to watch. Asummary output file includes min, max, and average exit times andfirst-in and first-out times for rooms and doors. Detailedinformation is available in CSV files, including movement ofindividual people.
In addition to the 3D display, charts of room occupancy and doorflow rates help you quickly evaluate points of congestion.
