Traffic Violations Visualized

  • Drivers city and Charge Description visually shown.  The area of rectangles and the font size signifies the count of violations
  • Violation count by race, by month visualized.  They are cross filtering, i.e. click to isolate for one race (e.g Asian) and you’ll see other visuals update to isolate/focus on your selection
  • Page 5, this visual shows “by Hour” violation count.  Each dial on the outer circle represents each hour on the clock.  This visual is really a powerful presentation, as audience can quickly see when the violations and pullovers are happening

Insights

  • Number of traffic violations (bar graph) and the average temperature (line graph) is also shown.  One would have guessed that there would be more traffic violations during the hot summer months (assuming people would drive more to go outside). But, the number of violations are actually less during June, July, August, when the temperature is high. March, April, and May seem to be the months with the highest number of traffic violations.
  • Also, it is interesting to see the count between “Warnings” and “Citations”. You can drill down or isolate for certain Year, Gender, or Race. You can see some interesting information as you slice and dice.
  • On page 3, the visualization shows the categories of violations. “Driving too fast” is the highest violations, followed by “Driving without active license”. “Driving without proper registration” is at the top of the list as well.
