This project includes scripts to visualize freeway station data in Portal. We wanted to explore how the solar eclipse on 8/21/17 affected traffic patterns, specifically, what speed-flow diagrams looked like.
Portal is the regional transportation data archive in the Portland-Vancouver metro region. http://portal.its.pdx.edu
Data are analyzed in Wilsonville, close to the I-5 Boone Bridge and I-5 Wilsonville freeway interchange. This is the southern-most point in the metro region available from Portal "stations" data".
- volume_speed_plots.R - make volume-speed plots for eclipse traffic
- animate_volume_speed_plot.R - animate the volume-speed plot by hour on the day of the eclipse
