June 2, 2011 <br />Page 5 <br />Savings Related to Reducing Delay <br />This calculation is related to the total amount of delay for the roadway network associated with this <br />intersection. Currently there is an existing pm peak hour intersection delay of 203 hours, which <br />would be reduced to three hours after the proposed interchange is constructed. This will result in a <br />total time savings of 200 hours. There are many different ways to calculate the value of time delay <br />with the most common method incorporating a dollar per hour per person for their time which <br />includes operation and maintenance of the vehicle. This is calculated to be $13.80 per hour per <br />person, or using the 1.35 occupancy rate, arriving at an $18.63 value per vehicle. The $13.80 value <br />was provided from the U.S. DOT Guidance of Travel Time in Economic Analysis, 2003. The <br />annual delay savings as calculated below amounts to $147,414/year. <br />PM Peak Hour <br />
