What is happening in California mirrors a nationwide decline in driving, experts say: The number of car miles driven annually peaked about a decade ago, and the percentage of people in their teens, 20s and 30s without driver's licenses continues to grow.
Although the decrease in driving and uptick in other forms of transportation seem promising, the study suggests an overall drop in the number of trips that could be cause for concern, said Brian Taylor, the director of the UCLA Institute of Transportation Studies.
"It's not better for society if we reduce auto travel by having people who are stuck home and can't afford to get out," Taylor said.
He said transportation planners aim to shift people from cars to other modes of transit without reducing the total number of trips. Typically, more trips means more people are working and have money to spend on errands and entertainment.
