    (b) Function.--
            (1) In general.--The Commission shall--
                    (A) make a thorough investigation and study of 
                revenues flowing into the Highway Trust Fund under 
                current law, including the individual components of the 
                overall flow of such revenues;
                    (B) consider whether the amount of such revenues is 
                likely to increase, decline, or remain unchanged, 
                absent changes in the law, particularly by taking into 
                account the impact of possible changes in public 
                vehicular choice, fuel use, or travel alternatives that 
                could be expected to reduce or increase revenues into 
                the Highway Trust Fund;
                    (C) consider alternative approaches to generating 
                revenues for the Highway Trust Fund, and the level of 
                revenues that such alternatives would yield;
                    (D) consider highway and transit needs and whether 
                additional revenues into the Highway Trust Fund, or 
                other Federal revenues dedicated to highway and transit 
                infrastructure, would be required in order to meet such 
                needs; and
                    (E) study such other matters closely related to the 
                subjects described in the preceding subparagraphs as it 
                may deem appropriate.
            (2) Time frame of investigation and study.--The time frame 
        to be considered by the Commission shall extend through the 
        year 2015, to the extent data is reasonably available.
            (3) Preparation of report.--Based on such investigation and 
        study, the Commission shall develop a final report, with 
        recommendations and the bases for those recommendations, 
        indicating policies that should be adopted, or not adopted, to 
        achieve various levels of annual revenue for the Highway Trust 
        Fund and to enable the Highway Trust Fund to receive revenues 
        sufficient to meet highway and transit needs. Such 
        recommendations shall address, among other matters as the 
        Commission may deem appropriate--
                    (A) what levels of revenue are required by the 
                Federal Highway Trust Fund in order for it to meet

                            (ii) improve the condition and performance 
                        of the Nation's highway and transit systems;
                    (B) what levels of revenue are required by the 
                Federal Highway Trust Fund in order to ensure that 
                Federal levels of investment in highways and transit do 
                not decline in real terms; and
                    (C) the extent, if any, to which the Highway Trust 
                Fund should be augmented by other mechanisms or funds 
                as a Federal means of financing highway and transit
