A Clear Roads review of snowplow route optimization projects showed that detailed data about a plow route network and close collaboration between route modelers and the operators who drive the routes are critical factors in an optimization project’s success.
The documents here provide users who are new to Recycled Asphalt Pavements (RAP) with Minnesota’s specifications, the findings from RAP use surveys in MN and nationwide, national trends, and resources to learn more.
Multi-lane roundabouts can be an effective intersection control and reduce injury crashes if the design and layout is carefully considered. Two LRRB-funded studies have recently been conducted to examine failure to yield and improper lane use violations. The findings are summarized here.

The purpose of this guide book is to provide easy-to-use steps for calibrating snowplow sander controllers. It is an experience-based guide that captures tips and techniques learned by experienced calibrators. It helps agencies calibrate their sander controllers so the correct amount of salt, sand or other solid material is applied to the road when treating roads during winter maintenance. The guide also includes calibration forms, and a general discussion about calibration.
