• 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
