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.

La respuesta correcta para esta pregunta abierta es la siguiente.
A pesar de que no se anexan opciones o incisos para responder a la pregunta, podemos comentar lo siguiente.
Yo considero que los sismos o maremotos (tsunamis) afectan de forma diferente a las diferentes poblaciones por dos razones.
La primera, la razón natural, es decir la intensidad del movimiento telúrico que genera el fenómeno llamado tsunamis. Sí, dependiendo de la intensidad del terremoto es la probabilidad de que ocurran tsunamis que puedan causar destrozos en diferentes islas o costas.
La segunda razón es la capacidad de movilidad de la población para poder prevenir los daños de este fenómeno. Es decir, los países del primer mundo puede detectar con mayor facilidad la presencia del tsunami y evacuar con cierta anticipación a las personas que vivan cerca de las costas. Ellos tienen la infraestructura militar y de Protección Civil para organizar una mejor logística y minimizar los daños materiales y humanos. Algo que no sucede en los países de tercer mundo, quienes sufren de los efectos de los tsunamis por no contar con la infraestructura adecuada.
