Over 128 million daily commuters in the U.S. and 75% report they drive alone. From improving traffic flow to air quality, convincing people to choose a possibly “greener” mode of transportation presents many challenges. Psychology researcher Gregory Thomas (Cardiff University) shows that if people are going to change their commuting habit, it needs to happen within the first three months of a move. He will present his research at the 18th Annual Convention of the Society for Personality and Social Psychology.
