The three lights at a traffic signal, namely the red, amber and green lights, either work in isolation (in response to the prevailing conditions of the local traffic and the pedestrians) or they are controlled by a centralised system that comprises a computerised network. The main purpose of this network of computers is to facilitate the co-ordination between networks of junctions. This is done in order to provide smooth progression of traffic during busy periods of time.

There are two places in the United Kingdom called Sefton and Merseyside. While Merseyside is the name of a county in England, Sefton is the name of a city which is located in the county of Merseyside. These places operate the most modern computer systems for the control of traffic, which have been supplied by Siemens Traffic Control.
