Via Newmark’s Door comes a different way to look at the numbers in the Texas Transportation Institute numbers. The post, from Prof. Peter Gordon, is very direct, but here’s the point and thrust:
1. Traffic congestion is a no-brainer; it is the default rationing mechanism because politicians are reluctant to price access. 2. It is remarkable how good traffic conditions are in spite of the policy failures; average journey-to-work times in the largest U.S. metros were less than 28 minutes at last census count (for solo auto trips). 3. These good news are explained by flexible land markets; most employers and employees find ways to locate within reasonable distances of each other. 4. The TTI index misses this phenomenon because it is constructed from metro area-wide average conditions; most traffic relief is found by relocations away from the metro area’s most congested parts. 5. Planners want to shut down this safety valve by increasing land use controls, making land markets less flexible. 6. New transit projects cause increased highway congestion because they take money away from road construction. California has pioneered this approach.
Now loop back to #2 on this list.
“Flexible land markets.” I like the sound of that.
