Abstract

Two microscopic simulation models CORSIM (Corridor simulation model) and AIMSUN2 (Advanced Interactive Microscopic Simulator for Urban and NonUrban 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.
