This chart shows all counts taken this year and summed all the times in 15 minute intervals throughout the city. (Four of the 15 minute segments were summed together to make the chart cleaner and easier to read, thus every point represents the hour following that time, i.e. a point at 7:30 is 7:30-8:30 not 7:30-7:45)
You can see the whole presentation here, close to the 30 minute mark. OR you can stay tuned for more future Charts of the Day! (And the first two charts, Year-to-Year Comparisons and Daily Use by Location).
