3.__Revenues for additional interchanges.__The authority may authorize highway revenues to be utilized for interchanges determined pursuant to the terms and conditions of this section, as long as the department may request use of revenues by submitting a proposed program for additional interchanges or improvements to existing interchanges and as long as the authority exercises sole discretion to set the level of revenues and as long as the additional interchanges or improvements have or would have a sufficient relationship to the public's use of the East-West Highway and the orderly regulation and flow of vehicular traffic using the East-West Highway so that the use of the highway revenues is warranted to pay all or any portion of the cost of maintaining or constructing the additional interchanges or improvements and all or a portion of the access roads required in connection with the East-West Highway.__In making the determination of whether a sufficient relationship exists, the department and the authority shall consider the following factors, no one of which may necessarily be determinative:

A.__The existing road network;

B.__The traffic impact of the construction or reconstruction on the existing road network;

C.__The probable change in departmental or authority expenditures resulting from construction or maintenance;

D.__The relative number of vehicles using or expecting to use those access roads on the way to or from the East-West Highway;

E.__The road distance of those access roads or portions of those access roads from the nearest entrance to or exit from the East-West Highway;
