The Town of Cottage Grove recently had the Dane County Highway Department conduct traffic studies on several busy Town Roads.
Pamela Dunphy, Deputy Commissioner of the Dane Highway and Transportation Division, will be at the July 16th Town Board meeting to discuss the results, which you can find posted online at the link below:
The study includes vehicle types (by axle) and speed data.
If you are interested in speed limits, another thing you may want to take a look at is Wisconsin Transportation Bulletin No. 21 Setting Speed Limits on Local Roads, which outlines what authority Towns do and do not have when it comes to setting speed limits.
