Crashes occur because of complex interactions between multiple variables, including driver behavior, environmental context, roadway design, and vehicle dynamics. Datadriven safety analysis (DDSA) models help State and local agencies quantify safety data, identify high-risk roadway features, and predict the effects of proposed safety measures. Howev

Speed limits are sometimes inconsistent within a jurisdiction for similar roadways. In some cases, this is because speed limits are applied to roadway sections based on characteristics which may not be obvious to the driver. For instance, speed limits on one roadway classified as a collector are set at 35 mph while another collector with similar ch
