%0 Journal Article %T TCP/IP Communication System for Controlling a Vehicular Traffic Intersection %A Pedraza-Mart¨ªnez Luis Fernando %A Hern¨¢ndez-Su¨¢rez C¨¦sar Augusto %A L¨®pez-Sarmiento Danilo Alfonso %J Ingenier¨ªa, investigaci¨®n y tecnolog¨ªa %D 2013 %I Universidad Nacional Aut¨®noma de Mexico (UNAM) %X This paper describes the development of a prototype of a vehicular traffic controller, whose system of communication is based on the TCP/IP protocol, in order to re- motely monitor and control the operation of traffic lights for a vehicular intersection. The results show the times of communication between the central and the traffic controller. The conclusions highlight the importance of using the TCP/IP protocol in traffic light systems. %K traffic controller %K traffic light %K vehicular intersection %K TCP/IP protocol %K open protocol %U http://www.ingenieria.unam.mx/~revistafi/ejemplares/V14N4/V14N4_art11.pdf
