How, and if, people travel on Memorial Day weekend can provide a fleeting glimpse at the state of the U.S. economy, or at least provide insight into consumer confidence. The upshot this year: a near record-setting travel despite a rising national gas price. Nearly 43 million Americans were expected to travel in cars, trains and planes over the long weekend — 1.5 million more than the previous year, according to AAA and Inrix, a global transportation company that aggregates and analyzes traffic data collected from vehicles and highway infrastructure. That’s the second-highest travel volume on record since AAA began tracking holiday travel volumes dating back to 2000, trailing only the bar set in 2005.
