I had an opportunity to install a bike counter at CR3 back in early June. It was located near the kiosk at the lead out trail. Check out the chart below for some results. Black bars are total riders by the hour, red bars are total for the day. The blue line is cumulative rainfall - note the drop in riders for days we had rain (although still some riding, tsk, tsk). Basically, the park saw an average of about 30 riders per day with well over 100 on June 6 and 7. I'm guessing this might be a result of the WORS race the previous weekend. I'm sure there other interesting details that can be teased out of the data. For example, the last black bar (far right of graph) was one of the largest. I was out there with a bunch of colleagues on a bike outing. The parking lot was full.
There may be opportunity to install one or more of these devices at other trail systems if there's an interest. Perhaps the data could be used to show state or county officials how much the trails are being used. Maybe certain days/times are more popular that others. Are some trails getting used all the time while others barely at all? Does a local ad campaign spike ridership in a certain area? I'm sure there are a bunch of other cool things to look at.
Anyone interested in getting the raw data can PM me and I'll email over an Excel spreadsheet.
