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.

The correct answer is climate!
Weather is the current state of the atmosphere (cold or warm for example) and global warming is the general trend for the average temperature to increase globally - but it's a specific weather-related phenomenon, not the statement of average historic temperature.

Explanation:
<span>The Senate is responsible for all lawmaking within the United States. The Senate also has important powers under the "advice and consent" provisions. They adjudicate proceedings initiated in the House of Representatives, a two-thirds majority being necessary for conviction. They consider and process legislation and exercise general control over government agencies and departments.</span>
