In the last few months, media reports have carried more questions about how 
  Mn/DOT decides on its priorities for highway construction projects. One of our 
  readers has been thinking about how to answer questions like these, and has 
  posed several questions about using benefit-cost analysis. 
Question: As a good business practice why doesn't Mn/DOT 
  track the benefit-cost ratios on all projects as a part of the programming criteria? 
  It would seem that this would require very little effort, be a good measure 
  in the use of tax dollars and aid in project selection in most cases?  
Answer:  Abigail McKenzie, director of economic analysis, Office of 
  Investment Management, responds:  “We agree. We do think that benefit-cost analysis 
  is a good tool for analyzing highway project alternatives. Benefit-cost analysis 
  is very useful in finding the alternative with the “biggest bang for the buck”—the 
  one that gives taxpayers maximum benefit for their tax dollars. 
“Mn/DOT has, indeed, been doing benefit-cost 
  analysis for a couple of years. Usually it’s applied to major highway 
  projects that cost more than $10 million, but has been applied to other types 
  of projects. Each district makes its own programming decisions after a detailed 
  analysis of alternatives that includes this technique for major projects.   
“The methods we use are specified by the 
  American Association of State and Highway Transportation Offices. They are comparable 
  to the methods used by Transport Canada, Transit New Zealand, and other transportation 
  organizations around the world. This method identifies the benefits to the transportation 
  user (our customers) in terms of: 
§         
  reduced travel time 
§         
  reduced vehicle operating 
  costs, and 
§         
  reduced crash costs (actual 
  costs incurred by individuals and insurers) 
“Benefit-cost analysis is a very customer-driven 
  approach. It focuses on what road users are getting for the tax dollars invested 
  in the project, with those benefits translated into monetary figures. However, 
  it should be looked at as ONE part of many factors, including: 
§         
  environmental issues 
§         
  municipal consent 
§         
  social issues, and 
§         
  business development issues 
“We do not recommend using it for transit 
  projects. It has some value here, but transit has many goals, such as:  
§         
  reducing urban sprawl 
§         
  providing mobility for lower 
  income people 
§         
  reducing pollution, and 
§         
  increasing a sense of community 
“It is valuable information, but it’s ONE 
  piece of information in a larger process that encompasses many other goals. 
   
“There is, at this point, no legislative 
  requirement to do benefit-cost analysis. It has been part of the legislative 
  requirements before, in an on-and-off fashion, for the last five to six years. 
  Rep. Phil Krinkie has proposed that it be revived. There is a Presidential Executive 
  Order that requires it on all federally funded projects—which is a portion of 
  our program.”
