Abstract:Winter road maintenance accounts for approximately 20% of state departments of transportation’s maintenance budgets; states and local highway agencies spend an average of $2.3 billion on winter operations every year. Nevertheless, over 5 million vehicle crashes occur in the U.S. each year, and approximately 21% of these crashes happen in the presence of adverse weather (e.g., sleet, snow, etc.). According to the National Highway Traffic Safety Administration, about 5,000 people are killed and over 418,000 are injured in weather-related crashes each year. These crashes also contribute to approximately $70.7 billion in property damages, including damages to the road infrastructure. Real-time road conditions information, especially road conditions images, provide valuable information to transportation operations managers to enhance their winter operations practices and improve road safety. The primary objective of this project was to develop a Snowplow Operations Management System to (1) collect and display a live feed of road conditions images from tablets mounted on snowplows; (2) collect and display on-demand road conditions images upon request by TxDOT staff either in field or office for real-time analysis; (3) collect weather information that facilitates snowplow operations decisions from national weather services for visualization alongside snowplow locations and road conditions images; (4) estimate road surface temperatures and visualize the road segments prone to icing hazards; (5) develop an easy-to-use, map-based ArcGIS interface displaying the collected real-time road conditions images, weather information from national weather services, road surface temperatures, and roads prone to icing hazards for safe and efficient operations of snowplows; and (6) estimate the implementation cost of the Snowplow Operations Management System in TxDOT, including the capital cost and operating cost.
