A letter report issued by the Government Accountability Office with an abstract that begins "Several factors—including rising rents, declining household incomes, and decisions to expand the number of assisted households—were key drivers of the approximately 29 percent increase (before inflation) in housing agencies’ expenditures for the voucher program between 2003 and 2010. Congress and HUD have taken steps to limit cost increases while maintaining assistance for existing program participants. For example, Congress moved away from providing funding to housing agencies based on the number of voucher-assisted households they were authorized to subsidize and instead provided funding based on the generally lower number of voucher-assisted households housing agencies actually subsidized in the prior year. Further, HUD has proposed administrative relief and program flexibility for housing agencies, including streamlining program requirements and reducing subsidies paid."

A letter report issued by the Government Accountability Office with an abstract that begins "State and local governments currently use ITS technologies in various ways to monitor and control traffic and inform travelers. For example, transportation agencies use cameras to monitor traffic conditions, signal technologies to control traffic flow, and dynamic message signs to inform travelers about travel conditions. By interviewing experts, GAO identified several emerging uses of ITS that have significant potential to reduce traffic congestion. For example, integrating traffic and emergency services data can allow for enhanced detection of and response to roadway incidents. However, some cities use ITS and the emerging uses to a much greater extent than others."
