"How to Build High-Speed Rail on the Northeast Corridor," by Alon Levy and Devin Wilkins of the Transportation and Land Use program at NYU's Marron Institute, makes a detailed technical case for faster, more reliable rail between Boston and Washington. We turned the report into an interactive site with a condensed version of the text and new maps and visualizations, so readers can follow the argument without working through the full document. We handled the UX design, mapping, interactive visualizations, build, and project management.
