Title 23, United States Code, §133(d)(2) and §160(e)(2), require that 10% of certain funds apportioned to a state pursuant to Title 23, United States Code, §104(b)(3), be used for transportation enhancement activities, as defined. The commission will allocate one-half of those funds to metropolitan planning organizations operating in transportation management areas as provided by Chapter 16, Subchapter D, of this title (relating to Transportation Funding). The commission may allocate funds to the department for activities that qualify for the Transportation Enhancement Program and are located on the state highway system, and may also make funds available in a statewide competitive program that enhances the surface transportation systems and facilities within the state for the benefit of the users of those systems. The sections under this subchapter prescribe the policies and procedures for the implementation of the program.
