Thanks for the great mention of Tri Track. For this article, I restricted myself to writing about existing technologies that are already widely used, so unfortunately I couldn’t talk about all of the exciting concept technologies still in development, like Tri Track.

Fortunately, I’ve been hearing a lot of talk among the US presidential and vice presidential candidates about improving public transportation. (Joe Biden actually commutes by train, making me hopeful for his support of public transit funding.) With the proper support, in the not-too-distant future we’ll see more innovative programs, like the one you’ve mentioned.
