An Application of the Fuzzy Technology in a Traffic Sound Signal

As an addition to the vision signal, this paper introduces a traffic sound signal based on the fuzzy technology which is designed and developed to give out speech and sound prompt according to the conditions of main road intersection, the device can automatically adjust prompt volume along with environment noise volume, thus reducing effectively the noise pollution. On-the-spot experiments proves steady operation and easy installation and clear sound prompt of the device which can offer great convenience to the blind pedestrians.
