Calculate ridership changes for new or modified services using Foursquare ITP’s Ridership Estimators. For any transit mode, we can provide accurate ridership estimates using our thoroughly-researched ridership elasticity calculator or the Transit Boardings Estimation and Simulation Tool (TBEST). For high capacity transit services, we can configure the Simplified Trips-on-Project (STOPS) model to produce high-quality ridership estimates that the FTA will have confidence in.
