The best traffic solution is dense housing near transit. We've known this for 30 years.
Every highway expansion study eventually comes to the same conclusion: you cannot build your way out of congestion with roads. Induced demand fills the new lanes.
But cities that built housing near transit? They didn't need to. When people can walk to a train, they don't drive to work. When they don't drive to work, traffic doesn't grow at the same rate.
We keep funding highway expansions and wondering why the congestion doesn't improve. The answer has been in the research for decades.
