About Subway Builder
Subway Builder is a hyperrealistic transit simulation game built using live data from US, UK, Irish, French, Swiss, New Zealand, and Japanese cities. Real-World Passenger Simulation Millions of commuters are generated from Census and Redistricter data and simulated using the same pathfinding algorithms you use on your phone. Your job is to design a route network that gets the most people to their destination as fast as possible. Juggle station placement, transfer dynamics, and train frequency to maximize ridership. In-Depth Analysis Explore how individual commuters weigh tradeoffs between wait times, transfers, income distribution, delays, and more, to pick their commute. Understand which routes, stations, and trains your commuters take and use that information to optimize your network. You must also find the right balance between cost and time using this analysis. Too many trains on a line or an overcrowded station may cause delays or disruptions. Authentic Data The US, UK, Ireland, France, Swiss, New Zealand, and Japanese census records home and workplace locations. The game generates millions of commuters with homes from that and then uses a distance-based gravity model to assign them all workplaces. They're also assigned times to leave to/from work in a distribution similar to real life. Please note that a broadband connection is required to maintain the real data used by the game. This decision is then made based on how long each commute method takes, how much it costs, and the value of their time (different commuters can have different incomes). If they decide to take the subway you can follow their commute (and thousands of others simultaneously) as they get to work. If a train is delayed or cancelled, it will affect their commute and future commuters will take that into account. College and airport commuters are also simulated and they behave differently since they have different income distributions and commuting times. Federal data is used for college student counts and FAA data for airports. Current cities in Subway Builder include: Atlanta, Austin, Baltimore, Boston, Charlotte, Chicago, Cincinnati, Cleveland, Columbus, Dallas, Denver, Detroit, Honolulu, Houston, Indianapolis, Miami, Milwaukee, Minneapolis, New York, Philadelphia, Phoenix, Pittsburgh, Portland, Salt Lake City, San Diego, San Francisco, Seattle, St Louis, and Washington in the US. Birmingham, Liverpool, London, Manchester, and Newcastle in the UK. Paris, Marseille,…Read more
