God what a bunch of whiners this city holds. Traffic here is actually quite moderate for such a large city. New York, Los Angeles, Washington and even Atlanta all have far worse rush hours. All of those cities also have much more extensive metro rail systems as well. Rest assured that even if the light rail system were greatly expanded here (and it definitely needs to be) there will still be traffic problems in Houston. Bad traffic is just part of living in the city. Don't like it? Move to the country.
What really amazes me about Houston though is how God awful the roads are. I have never in my life seen streets and high ways so poorly maintained as they are in Houston. Every time I visit Atlanta (where I lived for 2 decades) I marvel at how smooth and quiet the roads are. I certainly didn't ever expect to say something like that while I was living there either. And those roads are built and maintained without the benefit of multiple toll highways. Deferred maintenance, poor planing and lack of funding are the biggest problem with transportation in Houston metro. Until those problems are fixed the commute in Houston is not likely to improve.
