Donald Shoup, distinguished research professor of urban planning, was mentioned in a TAPinto article about the debate surrounding parking permits in Princeton, New Jersey. Princeton created a task force to invite public comment on allocation and pricing of parking permits. The task force is considering an increase in the price of parking and the establishment of a timeline to review parking demand and prices. Shoup has long argued that the price of parking should be adjusted until you have the right balance of occupied and vacant spaces. The article cited Columbus, Ohio, which adopted a parking permit plan based on Shoup’s recommendations. The Columbus system recalibrates parking rates every three months to balance supply and demand. It also uses a license plate recognition system to enforce paid parking and identify open parking spaces in real time.
