An interactive benchmarking tool that compares transit fares across cities worldwide. Every city is manually verified against official fare sources. The tool provides PPP-adjusted single-ticket and monthly-pass comparisons, effective per-ride cost modelling, affordability as a share of income, and fare structure classification (flat, distance-based, zone-based, hybrid, time-based). It includes a methodology summary, city-level detail views, and key findings on how fare structure and pricing interact with ridership, equity, and policy goals.
