The system, part of a trial in the UK of connected cars systems, provides a recommended speed to drivers which will help them avoid red lights.
The information for the system is provided by roadside transmitters connected to the lights system.
In addition to making a commute smoother and less frustrating, the idea has positive implications for fuel consumption and car emissions.
It's been estimated that in the UK, drivers on regular commutes typically spend the equivalent of two days a year stopped at red lights.
Ford is providing hybrid Mondeos for the trial, which involves 16 partners and is partly funded by the British government.
