To get started with NERPM-AB v2.2, download the model package and unzip the contents into a directory with read/write access. Ensure that the directory has at least 28 GB of free disk space for a scenario run. If not already installed, install the latest version of the PTV Visum software (2023 [SP 1-3] or above). Now, follow these steps to start a base or future-year model run:

  • Open the appropriate version file from the root directory by double-clicking the file. Open the NERPM_D2_2015_MAZ.ver file for the base year run and NERPM_D2_2045_MAZ.ver for the CF2045 run.
  • Before starting a model run, the project directories must be set to the root directory of the model setup. This ensures that all relative paths in the model scripts are valid. Set the project directories by selecting the ‘Edit project directories’ option from the main menu bar:
