Al discutir los conceptos estadísticos en el contexto de la planificación y las operaciones de transporte, Estadísticas de Transporte y Microsimulación proporciona los antecedentes necesarios para la toma de decisiones relacionadas con el transporte informadas. En él se explica el por qué detrás de los métodos estándar y utiliza ejemplos y problemas de transporte del mundo real para ilustrar los conceptos clave.
