However, other studies have found that red-light cameras reduce accidents and citations. A study by Texas A&M University found that accidents were reduced in Texas by 30%. Several studies funded by insurance trade groups which study traffic safety, have found the cameras had a dramatic effect and reduced accidents by as much as 30 percent. A study released in 2008 from the Texas Transportation Institute found a 30 percent reduction across the state. A study in Lubbock, Texas of red light cameras showed a 52% increase in accidents, so the City Council voted against installing them. A news investigation found that the Houston intersections with cameras often had yellow lights that were too short, and violated Texas Department of Public Safety recommendations. Houston suburb Sugar Land found that the combination of lengthening yellow lights and installing cameras reduced violations by 96 percent. This finding is consistent with a March 2005 Texas Transportation Institute study of 181 Texas intersections during a three-year period which found that increasing the length of yellow-light time by one second reduced violations by 53 percent and crashes by 40 percent. He was rated Governing Magazine'''s Public Official of the Year in 2007. Third term White's third term began in January 2008 with his inauguration at the Discovery Green Park. White made fighting pollution in and around the Houston area a top concern during his third term. He put pressure on local factories to limit pollution. He particularly emphasized reducing carcinogenic benzene emissions. He launched the Benzene Action Plan in 2007 which monitors benzene emissions and aims to reduce concentrations in the air. He forced Houston's largest refinery Lyondell Chemical Company, located along the Houston Ship Channel, to publicly defend its carcinogenic emissions. This received criticism from some businesses claiming White overstepped his powers as mayor, while he received praise from some citizens. In thanks to his fighting of pollution in Houston, White was awarded the HERO Award (Houston-Galveston Environmental Research & Outreach Award) on September 15, 2008. In August 2008, White traveled to Stavanger, Norway, one of Houston's sister cities, for an energy conference. On June 9, 2008, White revealed plans to increase solar energy capacity for the city of Houston. Solar panels were installed on the Code Enforcement building and the roof of the City Hall Annex building. Houston was chosen as one of the U.S. cities in the Solar America Cities program designed increase
