The congestion problem along HWY 401 in Ontario, Canada is identified as a key problem by Municipality of Durham in Freight Forum in 2022. The target study corridor identified by Municipality spans 62 km length with 26 interchanges on the Highway. We used PTV Vissim to evaluate several scenarios such as do-nothing scenario, implementing truck only lane. We also developed a 3D visualization tool by integrating PTV Vissim and Unity Game Engine that greatly aids stakeholders in comprehending the technical and general aspects of project.
