Gabe Klein

The gap between what's on the street and what cities can actually see, price, or enforce is the defining curb management problem of the next decade. And no one is treating it with any urgency.

Editor's note: As transportation commissioner for DC and later Chicago, Gabe Klein was pivotal in the development of a new model for big-city DOTs. Along with Janette Sadik-Khan in New York, Klein (who sits on the board of OpenPlans, the organization that publishes Streetsblog) pioneered an approach that prioritized people instead of cars and emphasized the importance of quick action to gain the public's confidence.
