The United States’ infrastructure quality has decreased drastically in recent years, falling from #5 in 2002 to #24 in 2011 in worldwide rankings. This decrease reflects the current inadequacy of transportation funding investments. Although federal transportation funding has nominally increased over the years, its real value has declined by almost 50%. Although federal funds account for a significant portion of transportation investment, states are responsible for almost half of transportation infrastructure revenues. Therefore, states should implement innovative, sustainable and flexible funding and financing mechanisms to facilitate transportation infrastructure investment.
