Project: Alternative Traffic Signal Control in Low Demand Periods

Reference: RED 12/12/52

Last update: 11/02/2010 11:52:23


The objectives of this project are to:

Investigate, assess and recommend possible options for alternative signal control at quiet periods


Traffic signal control is recognised and accepted, worldwide, as a powerful tool in the management of traffic in busy urban centres.

Whilst the use of sophisticated signalling systems and strategies have concentrated on benefits brought about by these systems during peak congested periods, not much is known about the use and impact of traffic signals in specifically low or very low traffic demand conditions.

Additionally, techniques such as turning signals off, reverting to a flashing amber mode have been suggested as ways of reducing vehicle delays at quiet times

The Department for Transport is interested to gather evidence on alternative signal control at quiet times with a view to investigating possible trials and informing future policy changes.
