Terrassa the sensors they made and with detailed data to the second, to Servei de mobilitat, TMESA and el Grupo avanza allowing access to buses data, and to GMV innovating solutions developers of the SAE of Grupo avanza by giving the technical details of the API and thus achieve develop a daemon that incorporates the bus dates to Sentilo Terrassa.<\/p>\n<p><a
