Miami's Beleaguered Metrorail Gets a Real-Time Report Card

Over the past week, more than 1,500 trains were scheduled to pass through downtown Miami’s Government Center Metrorail station. As of Thursday afternoon, just 383 arrived on time. The vast majority—927, to be exact—arrived late or bunched too closely to a previous train. And the remaining 208 never came at all.

That’s according to the Metrorail Audit, a new visualization of Miami Dade County’s struggling transit rail line, developed by TransitAlliance, a rider advocacy group for Miami. As a graphic depiction of a somewhat dysfunctional transit system, it’s elegant and oddly beautiful: Blinking, multi-colored dots unfurl across the top of the screen in real time, each one representing a train arrival (or lack thereof) so that the viewer can check in on the system’s performance every day.
