Cycling the Burke Gilman Trail in Seattle

I came across a dataset that records bicycle and pedestrian traffic on the Burke Gilman Trail in Seattle and decided to try out my D3 skills.

While living in Seattle, I rode to and from Fremont every day on the Burke Gilman bike trail. Little did I know that everytime I went past NE 70th St, I (along with everyone else) was being recorded… It turns out that hourly data of traffic on the Burke Gilman trail is publicly available online. I decided to try out my D3 skills and make a cute little visualization of an average day in the life of the Burke Gilman trail.

I took all of the data from 2017 and averaged the number of cyclists going in each direction by hour for each day of the week. I then plotted the data in a radial line plot (inspiration librally taken from this plot of twitter stocks) and added some transitions over time.

The end result (after 8 hours of work) turned out pretty nice. While it’s far from perfect, I’m pretty happy with my first attempt at creating a D3 visualization! The code can be found here:
