Following up on a post last month, there is some interesting bicycle count data to take a look at from the automatic counter located on the Custis Trail at Bon Air Park near the intersection with the W&OD Trail.

Showing the first two weeks of February in the graph above, we see that ridership was low during the first couple of days due to weather (in the 30s and rainy and residual snow). Towards the middle of the graph, there is a sharp spike when temperatures reached the upper 40s, and over the last two days you can see the numbers skyrocket as with highs above 50 degrees.

Another graph of interest shows the difference in ridership times on the weekend compared to a weekday. The above chart is broken down on an hourly basis and while there seems to be steady activity throughout Sunday, the afternoon when temperatures are at their highest is clearly the most popular riding time. On Monday commuting patterns become quite clear, there is a distinct peak in the morning and then another again in the afternoon.

As more automatic counters are installed over the next couple months we’ll be able to see these types of patterns in other parts of the county as well. Stay tuned for more!
