This project, funded by SSTI with a matching grant from the Center for Freight Infrastructure Research and Education (CFIRE),  identifies and evaluates freight transportation demand management (TDM) strategies to improve transportation efficiency by reducing the social costs associated with

VMT Inflection Point: Factors Affecting 21st Century Travel (SSTI, 2013)

For many decades, transportation planning has assumed continued increases in automobile use. Now, in a major reversal, the average American is driving considerably less. According to the most recent FHWA travel-volume report for July, total vehicle miles traveled showed no increase compared to
