• Abstract:
  The purpose of this report is to document the research activi ; ties performed under project SPR ; - ; RAC ; - ; 727 for the ; State of Vermont, Agency of Transportation, Materials & Research Section entitled “Optimization of Snow Removal ; in Vermont” ; . ; The overall objective for this project was to develop, for VTrans roadway snow an ; d ice control ; operations, storm ; - ; specific routes designed to maximize the efficiency of the service provided in terms of labor ; - ; hours and fuel ; . ; This report describes the set of processes implemented for optimizing RSIC operations for the ; roadways that VTran ; s is responsible for ; . ; Three different approaches to establishing priority for certain roadways ; are implemented, including one that uses the Network Robustness Index developed previously by researchers at ; the UVM TRC, and each is run for three storm levels ; – ; low ; - ; salt, medium ; - ; salt, and high ; - ; salt ; . ; Storm ; - ; intensity levels ; are important because they dictate the amount of salt application required ; - ; – ; 200 lbs/mile, 500 lbs/mile, and 800 ; lbs/mile, which is the primary constraint for the maximum length of a round ; - ; trip route for roadway snow and ice ; control. ; The first task was to optimize the service areas for each of the 61 VTrans maintenance garages based on the ; travel time between each garage and the surrounding road network ; . ; The second task was to develop alte ; rnative ; vehicle allocation methods and assign each of the vehicles in the VTrans RSIC fleet to the maintenance garages ; based on these methods ; . ; The third task was to optimally route each of these vehicle allocations according to the ; combined service time/f ; uel consumption metric ; . ; The fourth and final task was to evaluate the competing vehicle ; allocations based on the speed with which high priority road corridors are serviced
