Wireless Phone Based Emergency Response System (WIPER)

Laboratory prototype: Proof­of­Concept

Monitors a real­time stream of cell phone activity

Evaluates crises using Agent­Based Models (ABM)

Presents results and guidance for emergency responders

Simulation Tools Eclipse      Software for developing Java code

GeoTools   Loading geometrical information from                                           shapefiles

Repast       Agent­based modeling toolkit for simulating                                  agent behaviors 

OpenMap  Display tool for geographic information

PostGIS     Works with PostgreSQL as a spatial                                                database

GRASS     Tool for geo­spatial data management and analysis

Movement Models Fundamental Models    Null Movement                         A placeholder,  no movement 

   Random Movement                   Moving in a random fashion  

  Move And Return Movement     Back and forth between home and work                                                                 location     

   Basic Flee Movement               Moving along a straight line.

   Bounded Flee Movement         Agents stop after they reach a safe distance  

Extended Models     Road Flee                               Moving path constrained by road network   

    Congestion Flee                      Limited road sources generate traffic jams 

    Mixed Flee                              Pedestrians and cars evacuate simultaneously

Conclusions

Integrates  GIS­enabled Agent­Based Simulations and visualization tools together.

More realistic simulation: accurate Geo­spatial constrains on agent behavior. 

Enhance the decision making process of emergency management.

Geographic Information System(GIS)

GIS is an information system that integrates, stores, analyzes, and displays geographic information

Multiple applications:        Emergency response in the event of disasters

      Land protection from pollution
