Abstract:

The researchers undertook three major tasks to achieve the project’s objectives. In the first task, they focused on data conflation, integrating multiple data sources such as real-time traffic speed and volume data from the National Performance Management Research Data Set (NPMRDS), crash data from the Crash Records Information System (CRIS), weather data from the National Oceanic and Atmospheric Administration (NOAA), and roadway inventory data from the Road-Highway Inventory Network Offload (RHiNO). This merged dataset allowed for efficient analysis of the relationship between real-time traffic conditions, weather, and crash occurrences. The second task involved the safety evaluation of urban roadways. The researchers developed both annual-level and short
