Relationship Between Vehicle Miles Traveled and Economic Activity

If from VMT GDP, a directive legislation such as Federal Surface Transportation Policy Planning Act of 2009 reduce national per capita annually have adverse impact on overall activity. This study uses times series techniques test empirically Granger causality between various measures activity time. In most circumstances causal relationship found VMT; this confirms exogenous shocks will not negatively affect GDP. The VMT...
