Installation, Scenario Creation and Model Running

This page provides details on installing the AlaCC model and creating a model scenario for a particular year.

Model Installation and Scenario Creation

Step 1

AlaCC Bi-County Model installation files comes in the following three zipped folders:

  • BCM_Inputs - this folder holds the input files that are used to create the scenario inputs. There are inputs for four scenario years: 2015, 2020, 2035 and 2050. These files can be used to create a standard scenario for any of these years. Once a scenario is created based on these files, the model can be run as is to get a standard model run. Alternatively, for project analysis, end users can edit the input files based on project conditions, post scenario creation, to perform project specific analysis. The files in this folder are what is typically called as "master" files and are not meant to be edited by end users.
  • BCM_Model - This is the AlaCC Bi-County version of the MTC travel model one repository and has all the Cube job scripts, CT-RMAP configuration files, CT-RMAP parameter files and Python/R scripts. The scripts from this folder gets copied into a folder called "CTRAMP" inside scenario folder when a scenario is created.
  • BCM_Software - All the software needed to run the AlaCC model, apart from Cube are included in this folder. See the section ComputingEnvironment for details.

After downloading the three zipped files, unzip them to the same folder. Ensure that the unzipped contents look like below after unzipping.

Step 2

  1. The model assumes that Cube Voyager is installed in the default location (C:\Program Files\Citilabs\CubeVoyager). If not, please update the location in the file SetPath.bat (BCM_Model\model-files\runtime)
  2. Create a new scenario by running the batch file “createScenario.bat” in the folder BCM_Model\model-files. Before running createScenario.bat, make sure to update the locations shown in green and yellow below (SetUpModel_PBA50.bat file). The yellow highlighted locations are the unzipped folders in step 1. Green location is where the scenario will be created. This should take about a minute or less depending on the disk speed.
  1. CreateScenario batch file is currently set to create scenario for the year 2020. This can be updated by user to either 2015, 2020, 2035 or 2050. The field COMPUTER_SETTING in the SetUpModel_PBA50.bat batch file can be set at either MED or HIGH. The HIGH setting needs the computer to have at least 64 logical cores. MED needs the computer to have at least 32 logical cores. LOW setting is currently not supported.

Model Running and Post Process

Run the model by opening a command prompt in the scenario folder and typing the below command RunModel.bat > RunModel.log 2>&1

To create the core summaries and metrics, the batch file RunPostProcess can be run after a full model run is completed. This batch file can be run by opening a command prompt in the scenario folder and typing the below command RunPostProcess.bat > RunPostProcess.bat.log 2>&1
