Low Speed Vehicle Fleet Experiences
University of Oklahoma Adopts Variety of Alternative Fuels
Last Updated: November 10, 2009
The University of Oklahoma in Norman, Okla., has 160 vehicles that run on alternative fuels, including five low-speed electric vehicles. Two of the electric vehicles are used for on-campus mail delivery. OU also operates 43 electric utility vehicles and golf carts on campus sidewalks and paths that are used by maintenance and physical plant staff.
Beth Gatewood, OU assistant administrator of printing, mailing and document production, said the low-speed electric vehicles save the time and expense of refueling and are ready to go after recharging outside her building. "Besides being fun and quiet," Gatewood said, "we can get in all the small places on campus we need to squeeze through."
Central Oklahoma Clean Cities stakeholders since 1995, the University of Oklahoma Transportation and Parking Services, which includes Fleet Services operations and Cleveland Area Rapid Transit (CART), fuels 53 flex-fuel sedans and SUVs with E85, 41 heavy duty trucks and CART buses with B20, and 15 heavy duty and light-duty passenger vehicles and shuttle buses with CNG at its new Transportation Operations Center, a multi-fuel, state-of-the-art fueling, maintenance and operations facility. The center has four fast-fill CNG hoses at 3600 psi, and eight slow-fill CNG hoses in addition to four pumps for biodiesel and ethanol.
The university also has three hybrid electric passenger cars in its fleet that fuel at the facility which also dispenses gasoline and ultra low sulfur diesel.
At the official opening of the Transportation Operations Center in March 2009, OU President David Boren said the university is committed to the environment and the new Transportation Operations Center is a symbol of that commitment. Boren has made it university policy if an alternative fuel vehicle is available for the type of vehicle needed, the university will purchase the AFV.
OU Fleet Services plans to add five CNG buses to the CART fleet with 2009 federal stimulus money and will purchase and convert two new Chevrolet Impalas with assistance from an award from the Association of Central Oklahoma Governments' 2009 Public Fleet Conversion Grants program. ACOG's Public Fleet Conversion Grants? program is administered through its Clean Cities program office.
Chicago and Seattle Choose Segway Personal Transporters
Last Updated: March 18, 2009
The Chicago and Seattle city governments use the electric Segway Personal Transporter to boost worker efficiency, cut petroleum consumption and reduce greenhouse gas emissions. The City of Chicago, one of the technology's earliest adopters, owns 77 Segways. The police and aviation departments use them to patrol large areas such as parks and O?Hare International Airport. For police officers, the Segway provides the mobility and speed of a motorized vehicle while maintaining the friendliness of a walking beat. ?You can drive and still interact with the citizens,? says one Chicago police officer. City medical personnel and litter collectors also use Segways.
The City of Seattle operates 18 Segways. Utility department employees use them to check water meters, eliminating the need for cars on some residential routes. The Parks Department uses Segways to patrol parks and move between buildings. A city fire inspector, who had developed knee problems from walking his route in a concrete football stadium was able to remain on the job by choosing a Segway over a gasoline-powered golf cart and, as a bonus, prevented further joint problems. Parking Enforcement Officers are using Segways to patrol several downtown neighborhoods. Employees can also check out a Segway from Seattle?s motor pool to travel to nearby meetings.
Feedback from Segway users has been positive. Seattle fleet engineer Matt Rathke says he regularly receives Segway training requests. The Segway's all-electric operation eliminates gasoline use and emissions in both cities, and the fleets report saving money on fuel and maintenance. Chicago estimates that a Segway's annual maintenance costs are 20 times lower than a car.For more information, contact Eileen Joyce, Public Information Officer, Fleet Management, at eileenjoyce@cityofchicago.org, and Matt Rathke, Seattle Fleet Management, at matt.rathke@seattle.gov.
Redwood National and State Parks
Last Updated: August 22, 2007
Located near Eureka, California, the Redwood National and State Parks are currently using a variety of alternative fuels in its fleet. They are using biodiesel (B20) to operate 32 heavy-duty vehicles (HDVs) used for park maintenance. The park also uses five light-duty electric vehicles and two Toyota Prius hybrid electric vehicles (HEVs) for light maintenance and park transportation. In addition, the park has an electric tractor vehicle used to haul cleaning supplies to the restrooms, pick up and transport garbage, and to perform routine maintenance work. "The electric tractor is quieter than a conventional vehicle, and it does not disturb the wildlife as much," says Roads and Trails Supervisor Richard Mayle.Redwood National and State Parks currently has an onsite biodiesel (B20) refueling station. "Biodiesel is inconsistent because it usually takes a few weeks to get a shipment to our remote location. Sometimes the fuel arrives in a few days and other times it takes a couple of weeks," says Mayle. "Biodiesel also costs a little bit more than conventional fossil fuel diesel, but we have noticed that biodiesel is cleaner and seems better for the environment."

Seattle Tacoma International Airport
Last Updated: August 22, 2007
In 2001, the Port of Seattle Aviation Division adopted a fleet vehicle purchase policy that required the purchase of alternative fuel vehicles (AFVs), whenever feasible and practical, to replace conventional petroleum vehicles. The Seattle Tacoma (Sea-Tac) International Airport's fleet is currently composed of 60 compressed natural gas (CNG) vehicles, including 16 buses and 41 light-duty vehicles (LDVs)--all of which display the slogan "Doing our share for cleaner air naturally." Sea-Tac's fleet also includes seven propane LDVs, nine hybrid LDVs and 91 ground support units that operate on electricity. In 2005, the Sea-Tac Airport received the Environmental Protection Agency's Clean Air Excellence Award in recognition of the implementation of air quality programs such as the fleet vehicle purchase policy.
The Port required airport taxi and shuttle services to switch to CNG vehicles. Shuttle Express currently has 27 CNG shuttle vans serving the airport. Shuttle Express operates more than 33% of its total trip mileage using the CNG vans. The Seattle-Tacoma International Taxi Association operates all of its 166 taxi cab fleet with CNG-fueled Ford Crown Victorias. The Port of Seattle's Air Quality Web site reports that the CNG fleet is expected to produce 149 fewer tons of carbon monoxide and 24 fewer tons of oxides of nitrogen each year compared to conventional vehicles.
The Port partnered with Clean Energy to install, operate, and maintain a full-service CNG fueling station at Sea-Tac, which is open to the public and operates 24 hours a day. Sea-Tac currently has plans to add an additional public CNG fueling station, as well as increase the number of CNG buses in its fleet.
