Predictive Analysis for Work Zones

About This Innovation

FREeway EVALuation-Pennsylvania, or FREEVAL-PA, is a predictive work zone assessment tool for use by PennDOT employees and business partners. It is based on the Highway Capacity Manual and can be used to analyze roadways to determine likely results of events like work zones. It guides PennDOT's decision-making process for implementing lane closures, crossovers, or other traffic control methods and helps to minimize congestion and delays during construction or maintenance projects.
