It does not estimate increased economic development potential. MnDOT plans to conduct additional research into better methods for calculating the economic competitiveness benefits of a project for future Corridors of Commerce program selections. Freight Efficiency. For this criteria in the law it states, “measures of annual average daily traffic and commercial vehicle miles traveled, which may include data near the project location on the trunk highway or on connecting trunk or local highways; and measures of congestion or travel time reliability, which may be within or near the projects limits, or both.” To cover this criteria effectively, two project outputs will be used to calculate points; Travel Reliability and Heavy Commercial Average Annual Daily Traffic. Travel Reliability will be calculated using the same travel time data from the Return on Investment Travel Time Savings output, however the data will be looked at differently. Instead of calculating the travel time savings, the reliability of the roadway’s travel time will be evaluated. Both the percentage and degree of travel time un-reliability will be utilized to develop an index that can be compared to all the other projects. For more specific information about the Travel Reliability calculation, please consult the technical scoring system document also located on the Corridors of Commerce website. Heavy Commercial Average Annual Daily Traffic (HCAADT) will be taken from MnDOT’s traffic count volumes maps and used directly as this output. MnDOT will determine the closest HCAADT to the project or use a weighted HCAADT figure if more than one volume is available along the project area. Safety. This criteria in the law is a measure in traffic safety improvement. Safety is one of the few areas that can impact multiple scoring criteria. As noted in the Return of Investment criteria, 5-year Crash Savings from safety improvement from the project has already been given points. For the Safety Criteria, MnDOT did not want to use the exact same data from the ROI criteria. As a result, MnDOT decided to use two different outputs from its 5-year crash statistics for this criteria which measure the existing crash conditions of the project roadway in comparison to the other project roadways being scored. The two outputs being used are;
