A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning Approaches:
Reason:
In the context of work zone safety, worker presence and its impact on crash severity has been less explored. Moreover, there is a lack of research on contributing factors by time-of-day. To accomplish this, first a mixed logit model was used to determine statistically significant crash severity contributing factors and their effects. Significant factors in both models included work-zone-specific characteristics and crash-specific characteristics, where environmental characteristics were only significant in the daytime model. In addition, results from parameter transferability test provided evidence that daytime and nighttime crashes need to be modeled separately. Further, to explore the nonlinear relationship between crash severity levels and time-of-day, as well as compare the effects of variables to that of the logit model and assess prediction performance, a Support Vector Machines (SVM)
What is meant by machine learning approach?
Machine Learning is an AI technique that teaches computers to learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without relying on a predetermined equation as a model.

A
Explanation:
because it's a stronger education
Colombus and his followers began the process of the Exploration of Americas
Columbus was an italian explorer who completed four voyage across the Atlantic Ocean. He and his followers discover the Existence of America in 1492 during these voyages
Lewis and Clark Journey Home
Lewis' group took a shortcut north to the Great Falls of the Missouri River and explored Marias River—a tributary of the Missouri in present-day Montana—while Clark's group, including Sacagawea and her family, went south along the Yellowstone River
For the first question, is the first option because the allies wanted to understand clearly the weaknesses of the League. The answer for the second question is option four. Stalin believed that the Marshall Plan would restore Germany and make it a threat again. The combined effect of both the UN Universal Declaration of Human Rights and the Nuremberg Trials codified international humanitarian law.
