According to AAA, travel time on the northbound 5 Freeway between Los Angeles and Bakersfield at 4:30 p.m. Wednesday will take about 2 hours and 59 minutes -- an 88% increase compared to the normal travel time on that stretch of the interstate.
"Knowing when and where congestion will build can help minimize holiday traffic frustrations," said Bob Pishue, an INRIX analyst. "We advise drivers to use traffic apps, local DOT notifications, and 511 services for real-time updates."
AAA predicts that 55.4 million people nationwide will travel at least 50 miles from home between Wednesday and Sunday, the third-highest forecast ever by the auto club. AAA says most of them -- 49.1 million -- will drive, including nearly 4 million Southern Californians.
Over the comparable period last year, 37 people were killed in traffic crashes statewide, and the CHP arrested 1,016 motorists on suspicion of DUI and issued more than 8,600 citations for speed and seat-belt violations.
