Greater Yellowstone Regional Traveler and Weather Information System, U.S. Highway 89 Project

摘要

The transportation network that serves Yellowstone National Park has some operational challenges, including changing weather conditions, alternate routes that are separated by great distances, and animalvehicle conflicts. The purpose of this project was to develop, implement and evaluate a system to accurately provide necessary information to those who managed and utilized the transportation system along the U.S. Highway 89 corridor and other routes in and around the park. The project installed highway advisory radio stations at four of the five entrances to the park, and purchased the following portable equipment used to provide enhanced traveler information within the park as well as on roadways leading to the park: four portable dynamic message signs, two portable dynamic message signs with highway advisory radio transmitters, one portable highway advisory radio transmitter. Further, the park integrated its traveler information into the 511 traveler information phone systems operated by the Idaho, Montana and Wyoming Departments of Transportation to provide road condition and related information for travelers.
