Vehicle Travel

Applying the New Traffic Safety Paradigm

The new traffic safety paradigm recognizes exposure — total vehicle travel — as a risk factor, and therefore the additional casualties caused by planning decisions that induce more driving, and the safety benefits of VMT reductions.

How to Reduce Excess Vehicle Travel

Some experts claim that remote work is the most effective way to reduce vehicle travel, but my research indicates that improving and encouraging walking, bicycling, and public transit can provide larger impacts and benefits.

Peak Car Revisited

U.S. vehicle travel increased 3.2% (8.6 billion vehicle miles) in total and 2.0% per capita between Junes 2015 and 2016. That is a new peak in total VMT, but a 2.75% reduction in per capita VMT. Will these growth rates continue into the future?

An Inaccurate Attack On Smart Growth

Note: This column was originally titled, "A Stupid Attack on Smart Growth," intended as a pun on 'smart' and 'stupid.' However, that sounds harsh so I retitled it. - T.L. The National Association of Home Builders (NAHB) has a well-financed campaign to discourage communities from considering smart growth as a possible way to conserve energy and reduce pollution emissions. They contend that compact development has little effect on travel activity and so provides minimal benefits. The NAHB states that, “The existing body of research demonstrates no clear link between residential land use and GHG emissions.” But their research actually found the opposite: it indicates that smart growth policies can have significant impacts on travel activity and emissions.
