Spatially Agent-Based Model Demo

Project Overview

This project is a demonstration of a Geographic Information System (GIS) Agent-Based Model using Repast Simphony. It simulates the creation of agents based on real-world geographical data and integrates external datasets to enrich agent attributes.

The core functionality involves initializing agents from a vector Shapefile (.shp) and matching them with travel time data from a CSV file using a common identifier.

Key Features

• GIS Integration: Loads agents spatially using GeoTools/Repast Geography from Shapefiles.
• Data Fusion: Merges attribute data from CSV files into spatial agents. Implements an efficient lookup mechanism (HashMap-based) to merge.
  • Spatial Attributes : From Shapefiles (e.g., Region, Cluster ID, Urban/Rural status).
  • Socio-Economic Attributes : From CSV files (e.g., Travel Times, Access Costs).
• Scheduled Monitoring: Includes a monitoring class that dumps agent states to the console at specific simulation ticks.
• Utility Testing: Includes a standalone CSV parser test.
