PORTLAND, Ore. — An audit has found that Portland transportation officials aren’t collecting enough information to regulate the taxi industry.

The city’s independent auditor found that most of the city’s traditional taxi companies have failed to report required data, such as wait times and ride cancellations, that can help measure the level of service they’re providing, The Oregonian/OregonLive reported (https://is.gd/dzNCvq).

“The Transportation Bureau has focused on monitoring safety,” said audit services Director Drummond Kahn, “but now it needs to increase its monitoring of service.”

The audit found that most taxi companies have failed to turn over data on ridership, wait times and wheelchair-accessible service. The ride data is a particular concern because riders pay a 50-cent surcharge, which is intended to fund the cost of inspections and other administration.

Underreporting could result in thousands of dollars in fees not being paid to the city.

Portland last year removed much of its regulation of the taxi industry, including caps on the number of taxis and fixed prices, at the same time it legalized ride-sharing services such as Uber and Lyft, which now have seized 60 percent of the city’s ride market share.

The audit also uncovered some safety issues, including that the city has collected only crash data from the companies in aggregate, without information that would allow the city to identify problem drivers.
