Introduction

The vizTool is designed to help users explore and understand travel demand model (TDM) results by providing visualizations of various transportation metrics through maps and charts. Users can examine different data dimensions to support decision-making and explore the input data used in TDM calculations. With insights into travel behavior across geographies and transportation modes, the vizTool facilitates comparisons of information related to roadways, transit ridership, mode splits, socioeconomic factors, and access to jobs and households.

Accessing the vizTool

The vizTool can be accessed in two ways for WF-TDM v9.1:

  • Model Copy: A version of the vizTool is included within the WF-TDM model package.
  • GitHub Repository: Download the latest release from GitHub by following the release links.

The vizTool is also compatible with v9.0.x models with the help of a few scripts. To visualize older model data, please contact Bill Hereth for guidance.

Demo Version

WFRC hosts an online version with sample data, available here: WFRC vizTool Beta v9.1.0.

Running vizTool via LocalHost

A localhost is a means of using your own computer as a web server. You can run a localhost for the vizTool in multiple ways. Here are two options:

  1. Run the _open.bat file in the Scenarios/.vizTool subfolder. (Depending on networks security settings, sometimes this doesn't work)
  2. Run _start-server-static.py with your own python environment

Running vizTool on webserver

Copying the entire contents of the Scenarios/.vizTool subfolder will allow you to run it on your own webserver.
