Construction Project Traffic Impact Analysis Methodology and DTA Model Validation

MnDOT has been working toward better understanding of traffic impacts and Road User Costs associated with reduced system capacity during construction activities. In an effort to quantify those impacts, a Dynamic Traffic Assignment (DTA) / Mesoscopic Travel demand model was developed within the DynusT/DynuStudio software platform. This model has been useful for quantifying these impacts among various construction phasing ...more »
