Special coverage is given to the release of the Bottom Line Report, a comprehensive needs analysis by American Association of State Highway and Transportation Officials (AASHTO) and the American Public Transportation Association (APTA). the report finds the report finds that by 2015, governments at all levels will need to more than double their spending on highways and bridges to keep up with increased traffic, freight congestion, the demands of aging highways and bridges, and the growth of the nation's population. Transit spending would need to quadruple to serve increased rider ship. In exchange, smoother roads, less time lost to congestion, expanded transit service, and substantial savings in vehicle owner costs are the benefits Americans can expect. In 2006, federal, state, and local governments spent $79 billion on highways and bridges. However, investment of $166 billion a year is required, if the number of miles driven increases at an expected rate of 1.4 percent a year. If transit rider ship grows yearly by 3.5 percent, investment would have to increase to $59 billion annually. In 2006, transit investment was $13.3 billion. In addition, the report finds that another $13 billion would be needed annually for areas such as environmental mitigation, highway operations, safety programs, and security.
