Visualizations
Things I have made to make a pile of data legible: transit systems in motion, maps, and explainers.
In Motion
City-scale transit animations — every scheduled trip, animated across a 24-hour clock, with live vehicle overlays where open data makes it possible.
Toronto in Motion
Every scheduled trip across the Greater Toronto Area and Waterloo Region — 79,370 of them, from TTC and GO to a dozen local agencies — animated as moving dots, with a 24-hour scrubber.
Vancouver in Motion
Every scheduled trip across Metro Vancouver, the Fraser Valley and the Sea-to-Sky — SkyTrain, buses, SeaBus, BC Ferries, Aquabus and Hullo — animated as moving dots, with a 24-hour scrubber.
San Francisco in Motion
Every scheduled trip across the Bay Area — Muni, BART, Caltrain, AC Transit, VTA, ferries and more — animated with a 24-hour scrubber.
Seattle in Motion
Every scheduled trip across Puget Sound — Link, Sounder, Seattle's streetcars, King County Metro and the regional buses, Washington State Ferries and the Monorail — with a live vehicle layer.
Maps & explainers
Interactive maps, diagrams and small tools for questions that are easier to see than to read.
