There are many types of interchange configurations and intersection layouts that must be cleared during winter maintenance operations. These include, but are not limited to: diamond, cloverleaf, single-point urban interchange (SPUI), roundabout, Michigan left (boulevard turnaround), continuous flow intersection, diverging diamond, collector distributor lanes/interchange, and auxiliary turn lanes. There are numerous pass sequences that snow and ice professionals can use to clear a given snow route, intersection or interchange configuration. Agencies need a resource that provides guidance on the most efficient and effective means for snow removal utilizing common equipment setups.
This project will involve researching and documenting current snow removal practices used by transportation agencies to determine the most efficient practices for clearing various interchange and intersection geometries. The goal is to develop resources that will help agencies better train their operators, justify the purchase of specialized equipment, manage resources, and improve service levels to the motoring public.
