This document contains examples of water buildup locations on mileposted and non-mileposted roadways. While these examples may be used by some statewide agencies (e.g., ALEA and ALDOT) to address potential problems that could either be fixed or mitigated by enforcement, they also have value in training of local agencies. This training should include instruction on creating a water buildup filter, and how to run the high crash (hotspot) locations for both mile- posted and non-mileposted roadways. The next two sections contain example output display from four mileposted roadways and a statewide run for non-mileposted routes. A final section
presents of map of the mileposted and non-mileposted example locations.
