Urban public transportation is amidst a profound technological transformation—with teams rolling out everything from trip-planning apps to autonomous trains. And that’s helping make it more efficient, accessible and sustainable, says Graham Currie, director of the Public Transport Research Group in Melbourne.⁠ ⁠ Yet exploring new tech isn’t about racking up first-mover status. It’s about creating solutions for modern city life—and securing the necessary investment and governance to make public transit systems economically feasible for booming urban populations. “What we need is an ability to tap into this huge growth in a more cost-effective way,” he says on our Projectified podcast.⁠ ⁠ So while light rail has huge potential, it’s “far too expensive.” Instead, Currie’s got his eye on next-gen trams that can function without tracks or overhead wires—and take months to construct instead of years. “That could transform cities because they’re so much cheaper and doable,” Currie says.⁠ ⁠ Cl...
