In its most recent survey of available parking spaces on campus, the Cal Poly University Police reported 2,892 general purpose parking spaces, 3,492 dorm resident spaces, and 8,648 total spaces.[30] In its facilities Master Plan, the university admits that while more parking spots will be added, the actual ratio of parking to students will decrease since enrollment is expected to increase sharply.[31] To resolve the disparity, the Master Plan calls on the university to reduce the demand for individual vehicle parking. As part of that plan, the university has constructed additional dorms and has tried to make campus life more desirable. In addition, Cal Poly Commuter and Access Services has successfully promoted alternatives to commuting in single occupancy vehicles: in the past 10 years, bus use has more than doubled, and the use of bicycles has close to quadrupled.[32]
