Sir, - Could someone explain why so many traffic lights have been installed in the Dublin suburbs when small roundabouts, like they have in England and Australia, might be a better option.
For instance, there are four sets of traffic lights on Rochestown Avenue, Dun Laoghaire, within the space of about 200 yards, causing chaos. -Yours, etc., Aideen O'Connor
