AFTER THE BYPASS WHAT ARE THE BENEFITS....

The results of a "before and after" study of the effect of opening a new length of A61, the Ripley by-pass, are analysed and discussed. The study concentrated on surveys designed to measure the changes in traffic flow and composition, noise and air pollution, pedestrian activity and the commercial climate of shopping centres. It was found that 87 per cent of those interviewed after the opening of the by-pass thought that "it was a good thing". Of those, 97 per cent gave the reduction in heavy goods vehicles as the main reason for the improvement in the town centre. Some 70 per cent correctly decided that traffic speeds had not reduced and only 55 per cent considered the traffic less dangerous. Over 80 per cent interviewed said that there was less noise, a fact confirmed by a measured drop of up to 9 db(a) in places. Attempts to quantify the changes in trading in the centre produced inconclusive results but it appeared that trade had increased. (TRRL)
