Portland Traffic Visualizer

Browser-based traffic simulation for Portland metro area using parcel-level geospatial data, agent-based demand modeling, and WebGL2 rendering.

Quick Start

# Build data files (requires Python 3.10+)
make data

# Build WASM simulation
make wasm

# Run development server
make dev

Architecture

• Pipeline (Python): Fetches OSM, RLIS, Census, LEHD data and generates synthetic population
• Simulation (Rust/WASM): Agent-based traffic simulation with IDM car-following model
• Web (TypeScript/WebGL2): Interactive visualization with agent inspection

Requirements

• Python 3.10+ with pip
• Rust with wasm-pack
• Node.js 18+

Data Sources

• OpenStreetMap (road network)
• Oregon Metro RLIS (parcel data)
• US Census ACS (demographics)
• LEHD LODES (commute flows)
