Two microscopic simulation models CORSIM (Corridor simulation model) and AIMSUN2 (Advanced Interactive Microscopic Simulator for Urban and Non- Urban Networks) were compared for modeling of congested and uncongested freeway networks with on-ramps. The measures of effectiveness (MOE’S) compared includes flow, speed, and density. CORSIM and AIMSUN showed comparable results for uncongested conditions but results for congested conditions showed some distinct differences.
