• Abstract:
  The role of the REMI Policy Insight+ model in socioeconomic forecasting and economic impact analysis of transportation projects was assessed. The REMI
  
  PI+ model is consistent with the state of the practice in forecasting and impact analysis. REMI PI+, like its competitors, is vulnerable to the trends contained
  
  in the historical data it uses, especially recent trends. After the most recent periodic update in data, the performance of the REMI PI+ model improved, that
  
  is, it produced long‐term forecasts that were more credible. Zonal‐level population and employment forecasts for direct input to the Indiana Statewide
  
  Travel Demand Model (ISTDM) can be achieved by applying disaggregation regression methods. Indiana University’s Center for Econometric Model
  
  Research (CEMR) model is also a sound forecasting model. Because of the knowledge of in‐state economists, the CEMR‐IBRC model could provide forecasts
  
  of the Indiana economy that reflect characteristics not known to out‐of‐state forecasters. The researchers also examined economic impact analysis models
  
  that are possible alternatives to REMI PI+. Acquiring a new economic impact analysis package does not seem necessary for INDOT, if REMI forecasts can be
  
  adjusted to (a) accommodate recent and reasonable expected trends in the Indiana economy, and (b) meet the geographic (TAZ) needs of the ISTDM.
  
  MCIBAS—which is currently used by the Indiana Department of Transportation—is a good hybrid system to use in the economic impacts analysis of
  
  transportation projects. Indiana University’s CEMR is capable of conducting economic impact analyses, with local knowledge of the Indiana economy, at a
  
  cost lower than REMI’s. However, INDOT would have to decide whether these potential advantages justify changing the present relationship with REMI. In
  
  cases where the credibility of data, forecasts, and/or impact analyses needs to be verified, an INDOT version of an expert panel along the lines of Michigan’s
  
  Transportation Technical Committee could be convened.
