A research project commissioned by the Department and published in 2012 found that countries that were using flashing amber were moving away from it towards traffic responsive systems. In addition, there was some evidence that flashing amber led to an increase in accidents. The report can be found at https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/9209/traffic-signals-low-demand-periods.pdf.

Most traffic signals in the UK are traffic responsive, meaning that they use sensors to monitor traffic flow and adjust timings where needed, to reduce unnecessary delays. By keeping traffic moving as efficiently as possible, these systems can also reduce emissions and provide environmental benefits.
