We often think the solution to traffic is "more lanes," but urban planners call this "induced demand." When you widen a highway, more people decide to drive, and within a year, the road is just as jammed as before. To truly fix the "traffic driver" problem, we have to look outside the car.
High-quality public transit—trains, buses, and subways—acts as a pressure valve for city streets. Every person on a bus is one less two-ton metal box taking up space on the asphalt. The most successful cities in the world aren't the ones where everyone drives a Tesla; they are the ones where the wealthy and the working class alike choose the train because it’s faster and easier. Solving traffic isn't about making driving better; it's about making driving unnecessary.
