How we helped
The KEPSC team completed microsimulation analyses using Vissim for the I-495 interchange, and Synchro and SimTraffic for the Nutley Street and Chain Bridge Road interchanges. For Nutley Street, the corridor extending from Route 50 to Marshall Road was modeled. For Chain Bridge Road, the analysis covered the corridor the segment between Route 29 and Jermantown Road.
ResultsKEPSC completed the operational analyses within the scheduled timeframe and the modeled conditions are currently being implemented as the three (3) intersections are undergoing construction.
