Subway Builder

Design a hyper‑realistic subway / transit simulation
Build a subway network from scratch, subject to real‑world constraints: foundations, geography, roads, cost tradeoffs
Millions of commuters are generated from U.S. Census data and assigned homes and workplaces; they choose routes based on time, cost, transfers, and incomes
Delays, cancellations, and overcrowding influence future commuter decisions and network performance
The simulation distinguishes between regular commuters, college, and airport traffic, each with different behaviors and income distributions
The game offers a “lightweight” performance footprint—if your computer can run Google Earth in Chrome smoothly, it should handle Subway Builder
