Abstract
The control and analysis system for traffic lights is principally based on an autonomous central processing unit which operates with software that enables it to detect and control an auxiliary electrical supply device, the consumption and the electrical resistance, for determining whether any lamp has blown, according to which reading it checks and decides at each moment on sending a suitable signal to a transmitter-terminal.
