• Abstract:
  Using intelligent transportation systems to help report traveling conditions has been reserved for urban
  
  areas. The goal of this research was to help develop a new methodology for incorporating travel times
  
  calculated from intelligent transportation system (ITS) technology into Wyoming’s road and weather
  
  condition reporting system. Bluetooth sensors and speed sensors were used to measure travel times on I-80
  
  between Cheyenne and Laramie, as well as WY-28 between Farson and Lander in Wyoming. From
  
  previous research, the distribution of travel times on I-80 show two distinct modes. Travel times from the
  
  WY-28 corridor were then calculated to determine if this trend was common with other rural highways. The
  
  next step in this research was to determine the best way to measure travel times on a rural corridor.
  
  Bluetooth sensor travel time data was compared to speed sensor travel time data. Then a travel time index
  
  was created for I-80 from one year of speed sensor data. This travel time index was then modeled with
  
  weather variables downloaded from road weather information system (RWIS) stations. Finally, a
  
  methodology for implementing and evaluating this new travel time reporting procedure was developed. The
  
  results of this research will help to improve the current condition reporting system by incorporating both
  
  physical conditions (slick in spots, high wind speed, etc.) with travel times. This will help all types of
  
  travelers to more accurately quantify the severity of traveling conditions.
