SAN FRANCISCO (KCBS)— A new study finds that SFpark, the two-year-old program that uses fluctuating pricing to control parking space availability in San Francisco, is working.

Many initially thought the program was ambitious for its attempts to solve the city’s hefty parking problems. The approach has been tried out in six of the city’s busiest areas and varies the price up and down as needed to meet the demand.

San Francisco Municipal Transportation Agency’s Director of Transportation Ed Reiskin said the time spent searching for parking has been reduced.

“What we’ve been able to do with SFpark is really take parking management to the next level. A quantum step forward,” he said.

Reiskin said the program created more spaces and even lowered overall meter prices a bit in areas where parking isn’t as difficult.

“We are communicating with the people who are looking to drive around and park in our cities and trying to make that all work better that benefits the entire city,” he said
