Sir – I was delighted with your front page story Switch off the traffic lights (March 3). A few months ago you published a letter from me explaining that only twice have I experienced an easy run into Oxford along the Botley Road when there were power cuts and the Frideswide Square traffic lights were off. I appreciate the comments from pedestrians and cyclists, but isn’t it about time the county council took some notice and conducted a few trials, say over a month, with the lights off at different times of the day to gauge the effect on traffic movement before spending huge amounts of money needlessly.
