The CBO estimates that an increase of ten cents a gallon would be required in 2015 simply to offset the last 16 years of inflation and fuel-efficiency gains and to maintain current (inadequate) funding levels. A considerably larger hike would be needed to prevent the underinvestment predicted by the ACSE.
国会预算办公室估算，若要在2015年弥补过去16年的通胀和燃料效率提高影响并维持当前的融资水平（处于不足状态），汽油价格需要调高10美分/加仑。要阻止ACSE所预测的投资不足情况，需要大得多的涨幅。
