In many cases cities and counties have more vehicles than they need in their fleets. By analyzing the operational needs of your fleet, and eliminating excess vehicles, non-critical trips will be discouraged and alternative forms of travel encouraged. Eliminating fleet motor vehicles in favor of bicycles can have substantial advantages as well. Employees can use bicycles for local trips. Moreover, putting police officers on bicycles offers crime enforcement advantages and substantial savings, as well as emission reductions.The police department in Dayton, Ohio is saving 2,700 gallons of gasoline and 7.5 tons of CO2 a year by using bicycle patrols instead of police cars.
