The Chicago Department of Fleet and Facility Management (“FFM”) initiated the project in cooperation with the Chicago Budget Office and conducted a review of the purchase, maintenance, fuel reports, and parking expenses. Vehicles with under 50% average utilization were targeted to be retired or switched out. Once under-utilized vehicles were identified, a method to replace them was developed using pre-existing solutions from two sharing economy contractors: Zipcar and Flexfleet. As an update, in spring 2018, Chicago awarded another vendor the car pooling program, and expects 5-10% in additional savings for this contract.
