Once the index is determined for each intersection, a tree was fitted for each one of them, which is considered as a training stage, where three models were fitted and which response corresponds to the index value computed from principal component analysis.
Una vez determinado el índice para cada intersección, se ajustó un árbol por cada una de ellas, etapa considerada como de entrenamiento, donde se ajustaron tres modelos cuya respuesta era el valor del índice calculado a partir de las componentes principales.
