Affordability as a Transportation Planning Objective

What do transportation system users consider to be the most important problem? Here’s a hint: it’s not traffic congestion.
The 2009 National Household Travel Survey asked respondents to rate the importance of six transport problems: traffic safety, congestion, price of travel, availability of public transit, and lack of walkways or sidewalks. Virtually every demographic group rated affordability (“price of travel”) most important, as indicated in the graphs below.

Affordable transport is important, particularly for lower-income people. Increased affordability is equivalent to an increase in income.
Yet, conventional planning ignores this concern. Affordability is seldom recognizes as a transportation planning objective, and if it is, it is usually evaluated based simply on fuel costs. Conventional planning ignores vehicle ownership and parking facility costs, which are much larger than fuel costs, and so ignores the inaffordability caused by automobile dependency and the user savings that can result from increased transport system diversity and land use accessibility.
