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 options are
A. about 10% more; racial discrimination and immigration.
B. about the same; union dues and cost of lawyers for collective bargaining.
C. about 20% more; years of work experience and education level.
D. about 30% more; healthcare and retirement benefits.
C. about 20% more; years of work experience and education level.
D. About 30% more; healthcare and retirement benefits
The answer is C. about 20% more; years of work experience and education level.
Union members are the active participants in the interest groups representing a cause. This is usually to push for the improvement of the welfare of members of the group of people under them.
It is understood that Union members earn about 20% more than non-union members, even after adjusting for factors such as years of work experience and educational level.
