Autonomous City of Buenos Aires

The City of Buenos Aires is the largest urban center of Argentina, with a population of 3,000,000 and a population density of 14,900 persons per square kilometer.
Together with its metropolitan area (grand Buenos Aires) it is the second city in South America and of the largest urban centers in the world. With respect to its transit infrastructure, it has 3,650 traffic signal crossings, of which 2,601 are communicated to two transit command centers, 3ct, featuring four CITAR Le Transit computers, and 2ct (plan 2) featuring three area local computers: one R30 and two CITAR Le and three area 3 remotes: one R30 and one CITAR Le, area 6: one R30 and two CITAR Le, area 7: one M56 befaba. The communications, between computers and controller equipment, are conducted via pairs of telephone wires located in underground ducts with a length of approximately 350km. In addition, it features a laying of more than 30 km of fiber optic cable that allows for communications with the transit computers and to receive video from more than 35 CCTV cameras located on public roads. There are two short-term plans to amplify infrastructure: The first is to construct 100 new crossings, which would be able to communicate with transit computers, and the second, a plan to extend to an even greater length the optic fiber cables and CCTV cameras.

Transit management also uses 3 traficams and 3 traficoms, and plans to put in place twenty traficams more.
