Additionally, the company made significant progress on its network expansion plan during 2006 and noted a dramatic increase in fleet usage.
IdleAire's ATE technology is a commercial idling- reduction alternative that reduces idling costs of heavy-duty diesel engines; provides a key driver retention and recruiting benefit; provides a healthier sleep environment for drivers; reduces air pollution from idling diesel engines; conserves fossil fuel energy; and improves highway safety by reducing sleep deprivation.
Independent research indicates that drivers that idle their heavy-duty diesel truck engines for comfort during federally-mandated rest and recharge periods consume on average about one gallon of fuel per hour and emit 10,598 grams of air pollution per hour. For the year ended Dec. 31, 2006, the company saved its customers more than 5 million gallons of diesel fuel and eliminated over 53 thousand metric tons of diesel pollution, including 114.9 million pounds of carbon dioxide greenhouse gases associated with global warming.
During the fourth quarter of 2006, IdleAire added 32 sites and 2,188 ATE spaces. As of Dec. 31, 2006, the company was operating at 99 locations in 26 states, a 313 percent increase over the 24 sites operating as of Dec. 31, 2005, and had a total of 6,559 ATE-equipped parking spaces, a 381 percent increase over the 1,365 ATE spaces operating as of Dec. 31, 2005. During 2006, IdleAire deployed its technology in 78 new travel center locations and two fleet terminals. Additionally, five sites were closed and the usable equipment relocated to other sites.
