• 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.
