Highway Rail Intersection (HRI)
Mn/DOT, in cooperation with the project partners, developed and installed the HRI System at 27 selected low volume crossings on the Twin Cities and Western Railroad (TC&W) corridor in Minnesota between the Twin Cities and South Dakota. The purpose of the Low Cost HRI Active Warning Project was to determine whether the system could perform as well, or better, at low volume crossings than the more costly traditional active warning systems.
