As congestion worsens, people will move closer to where they work. As conjestion lessens, people move further from where they work. Trying to overcome these tendencies is futile.
I'm not sure where you live, but in my experience it works exactly the opposite. As congestion has increased tremendously here in the Washington D.C. area the last 10-15 years, the areas with by far the most growth have been the outer-ring suburbs more than 20 miles away from the city. I believe that the cost of real estate and whether one is single or married are far bigger factors in determining where people choose to live than congestion.
