The modeling team developed detailed microscopic models of traffic operations with the solution alternatives for the base year 2017 and less detailed mesoscopic models for other areas in the Valley where the team wanted to gain a general understanding of traffic patterns. The dynamic models used Aimsun Next traffic modeling software and incorporated macroscopic (regional) analysis from the Regional Transportation Commission of Southern Nevada’s (RTCSNV) static travel demand model.
The team used the different levels of analysis (mesoscopic or microscopic) depending on the corridor being analyzed. Corridors with recent project development, or corridors that would have less congestion in 2040, received a mesoscopic level of analysis. To document future congestion and to identify and develop the project alternatives, corridors that would have more congestion in 2040, or corridors slated for alternative development as part of the SNTS, received a microscopic level of analysis.
