Chicago Area Travel Model User Group

Oct 24, 2013

Chicago Area Travel Model User Group

CATMUG (Chicago Area Travel Model User Group) was formed in 1997 as a forum to share and discuss travel model research and application efforts among the Chicago area transportation planning community. CATMUG is a multidisciplinary group of over 100 members including engineers, planners, professors, and researchers. CATMUG normally meets at noon on the first Wednesday of each month at CMAP. It is coordinated by Nick Ferguson. Please contact him to be added to the e-mail distribution list.

Topic – A R-based Visualization Tool for Travel Demand Models
Presenter – Ken Kaltenbach,  The Corradino Group

Corradino has created a “rMarkdown flexdashboard” (dashboard) as an interactive tool for planning and analysis using the outputs of TCRPM5. It is intended to be a tool for FDOT, MPO, and consultant staffs to verify that TCRPM5 ran correctly, an aid to model calibration and validation, and a tool for developing the LRTP and other transportation planning studies. It will be useful for developing graphs, maps, and tables for study documentation. 

A key feature of the dashboard is that it will be produced every time the model is run, just as the traditional HEVAL report is produced. Thus, the dashboard always will be fresh and up-to-date, and no extra steps will be required to generate the data and produce the dashboard. The dashboard will be rendered as an “html” file, which can be opened and viewed in a web browser, providing an interactive window into the results of each model run.

The dashboard provides the means to efficiently access and use the rich output of the CTRAMP activity-based (ABM) model. Even for the Treasure Coast region, the ABM travel logs produced by the model are big. Joining and viewing these databases is cumbersome using tools like spreadsheets and Cube Matrix and other database tools. R provides an extremely efficient solution. The databases combined using R scripts can be analyzed, and the results can be displayed in maps, tables, and graphs. R provides a host of tools for statistical analysis, and libraries for creating detailed and interactive maps, tables, and graphs (plots). Using R, it is possible to provide travel analysis for groups of travelers based on all synthetic population and household attributes, and the disaggregate travel data output by TCRPM5. Of course, this is the justification for ABM’s, yet without the proper tools, like the visualization dashboard, planners have difficulties accessing the disaggregate data. The dashboard for TCRPM5 provides:

  • Maps, using the “leaflet” libraries. Leaflet maps use “Open Street Maps” as the background for all displays, providing a rich context for all model data maps.
  • “Kable” tables, that automatically generate detailed and attractive tables displaying statistical summaries of data.
  • “gglot2” and “plotly” graphs, which generate a wide range of charts and graphs of the data. What’s more, the graphs are interactive, and details of points and lines on the graphs can be displayed as the user “mouses-over” the graphs.

The dashboard is created in the Cube flowchart as a standard “html” file, which can be viewed in any web browser. All contents can be captured from the browser and pasted into spreadsheets and reports.
