The study finds that region-wide, households spend an average of $23,000 on housing and $13,000 on transportation annually, and that increases in transportation costs start offsetting housing savings when families locate roughly 16 miles from employment centers; drivers who spend an average of 60 hours per year sitting in traffic and waste nearly 91 million gallons of fuel.
To lower the housing-transportation cost burden for the Washington metro area, the report suggests that part of the answer is “creating more housing and transportation choices...us[ing] our existing infrastructure more wisely and more intensively...and [m]ore compact development." The report predicts the addition of 1.7 million new households over the next 20 years in the DC region, half of which will occur in the outer suburbs and outer-ring jurisdictions. These areas currently are home to just over one-fourth of the region’s population, and have the highest combined costs for housing and transportation.
