About the research

The purpose of this research project is to develop visualization techniques and methods that display the pavement performance data and information in a communication-friendly format for a variety of end-users. Several possible scenarios of end-users and possible questions for which they might use visual analyses to answer are envisioned. We believe the two primary end-users of these visualizations are engineers working with the datasets and county office administrators examining the status of the roads in their counties and the state.

Accordingly, several visualizations are presented that would be useful for each of these end-user groups. For each, a short description is given along with a sample question that the visuals could be used to answer. The dataset used is provided by the Iowa Department of Transportation that outlines numerous indicators of pavement performance for 2013. Software programs used to produce the visual analysis are Microsoft Excel 2010 and Tableau 9.0.

The visual analysis is interactive and is designed to provide a dash board at the county level. It can be modified to display information and visuals at other levels of county groupings.
