This surprised me
"By the Texas Transportation Institute's reckoning, the cities having the worst traffic problems are:
1. Los Angeles, Long Beach, Santa Ana, Calif.
2. San Francisco, Oakland, Calif.
3. Washington, D.C.
4. Atlanta
5. Houston
6. Dallas, Fort Worth, Arlington, Tex.
7. Chicago.
8. Detroit
9. Riverside, San Bernardino, Calif.
9. Orlando, Fla.
11. San Jose, Calif.
12. San Diego
California has a decided edge in winning the award for the worst traffic, since five of its cities (or city regions) make the top 12 list. Several of the cities mentioned are well known as trucking, rail, air and sometimes sea hubs for logistics. The convergence of services taxes the infrastructure."
