(San Francisco – KALW) The city of San Francisco is making its first round of changes to parking meter costs based on data gathered from its street sensors around town. The idea is for meter and garage rates to be based on demand – so popular blocks will cost more, less crowded ones will be cheaper, and everyone will spend a little less time circling the block. How’s it working?

According to Jay Primus, the manager of the program, “it’s a little bit like the Goldilocks principle. We don’t want it too hot, we don’t want it too cold – we want it just right. In this case, prices not too high or too low, but just right for the demand we see.”
