Visualizing and comparing retroreflectivity prediction results using ggplot2 and Plotly

Last summer, I wrote a TRB paper in which piece-wise multiple linear models (PMLMs) were developed to predict pavement marking retroreflectivity in Minnesota, Pennsylvania, and Florida.  The primary goal of the paper was to develop robust models that can predict retroreflectivity of pavement marking materials under various winter weather conditions. In the paper, I compared […]
