Effect of the Weather Events on Travel Time Reliability and Crash Occurrence


On average, nearly 5,000 people are killed, and more than 418,000 people are injured in weather-related crashes every year in the United States. About 23% of the non-recurring road delay around the nation can be attributed to snow, ice, and fog. The precipitation, which occurs more frequently than the snow and fog leads to more traffic delay. Ensuring higher levels of travel time reliability and safety are critical for efficient transportation system management. The main objective of this research is to establish a methodological framework for capturing, processing, and integrating weather events-related information, travel time, and crashes for selected road links in the state of North Carolina.
