Business travelers are bypassing the taxi queue with greater frequency, choosing instead ride-hailing services such as Uber Technologies.

A new report by expense management system provider Certify shows that 47 percent of the ground transportation rides by its users in March were through Uber. That’s more than tripled from the 14 percent of rides that Uber had just over a year ago in January 2014. In a few cities, Uber now tops taxi rides for business travelers.
