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.

Dear eriabn
Answer to your query is provided below
Slave trade was a trade of slaves from Africa. It was between three countries, Africa ,France and America. Slaves were bought from Africa and then packed in ships for three months and later on sold to the plantation owners on the port of baundeax in France. Others were sold in America.
Explanation:
Slavery refers to a system whereby people were ill treated and forced to hard work.
The Europeans were reluctant to go and work in distant and unfamiliar lands meant a shortage of labour on the plantations. So this was met by a triangular slave trade between Europe, Africa and the Americas. The slave trade began in the seventeenth century. French merchants sailed from the ports of Bordeaux or Nantes to the African coast, where they bought slaves from local chieftains. Branded and shackled, the slaves were packed tightly into ships for the three-month long voyage across the Atlantic to the Caribbean. There they were sold to plantation owners. The exploitation of slave labour made it possible to meet the growing demand in European markets for sugar, coffee, and indigo. Port cities like Bordeaux and Nantes owed their economic prosperity to the flourishing slave trade.
