Para llevar a cabo dicha tarea se usó la base de datos del proyecto NGSIM, específicamente, la información recolectada en la carretera I-80. Además, para hacer una comparación equilibrada también se estimaron los parámetros de las relaciones clásicas sin la modificación lineal de la variable espacial.]]></p></abstract>
