This report evaluates the results of a survey that was conducted by the Iowa Department of Transportation to study the existing conditions, the way the system is performing, short and longterm issues and strategies to improve the I-80 in Iowa from Illinois to Nebraska borders. The goal of this component of the I-80 study is to gather feedback from the general public and evaluate, visualize the results which would be vital for the management while making decisions about the investment and development plans of the I-80. After the analysis of the quantitative component of the survey, we could clearly display the public opinions through a series of visualizations which gives the management the required information to consider in the decision making process. The qualitative component of the survey was analyzed using Natural Language Processing by implementing the Latent Dirichlet Allocation algorithm. Although the results of the qualitative analysis were not conclusive as we would have expected, they still give an idea of the various steps that could be taken by the DOT which would have positive and negative impacts on the public.
