Prior to the conversion date and within one year following the conversion date, the commission, in collaboration with the department, shall conduct traffic studies to determine the average daily traffic on associated roads and highways. The purpose of these studies will be to quantify any diversion of traffic from Interstate 80 to other roadways as a result of the conversion. This section shall not require duplication of traffic studies undertaken by the commission as a part of the conversion process or undertaken by the department as a normal course of the department's operations.
