7.4 Version NERPMAB2.2

This version was developed using PTV Visum modeling software and includes the following updates:

• Highway and transit networks for 2015 and 2045were imported into Visum from the previous model

• The version files contains all network inputs and settings for running the model

• AN integrated system was developed using Visum's Python API to interface PopulationSim, DaySim Data Tools, and DaySim with Visum. This resulted in streamlining of workflow for various modeling tasks for the agency staff

• All procedures from the previous model were implemented using built-in procedures in Visum or in Python using Visum's Python API

• A major skim replacement bug was fixed which resulted in premature convergence in the previous model. VISUM Model corrects the replacement and averaging of skims which results in more iterations for convergence

• A highway validation dashboard was developed for easier viewing of calibration and validation summaries

• The Visum model provides various other benefits such as:

 * faster run times
 * ABM data visualization
 * On-the-fly flow bundles
