Doing some more searches the gasoline tax increase to 4¢ was included in the Federal-Aid Highway Act of 1959. According to 1963 edition of The Statesman's Year-Book, a publication no good home should be without, for the financial year 1960-61 the Highway Trust Fund received $2,925 million in income and spent $2,746 million, which ignoring the economic effects of raising it to 5¢ would have for simplicity's sake works out to $731 million for our proposed Mass Transit Account. Have it operating in a similar manner to the Highway Trust Fund with federal government covering 80% of the costs and the states covering the remaining 20% gives you a potential maximum budget of $914 million for the year. Cities and states can of course spend extra out of their own funds.
