"Similar to the REMI model, the Economic Development Research Group has developed a model called the Transportation Economic Development Impact System (TREDIS). Unlike REMI, it’s currently limited to single-corridor or single-region applications <ed note: this restriction from 2005 is no longer applicable> , but similar to REMI, it can estimate the full economic effects of transportation cost changes. In addition, it incorporates a module called the Local Economic Assessment Package (LEAP) that estimates potential business attraction effects from accessibility improvements." (page 3-39)
