Please be aware that the need for audible traffic signals is a legitimate request from individuals who are striving to be independent. The idea of independence is not placing ourselves in unnecessary dangers as we travel but is to allow blind individuals to be confident and safe as we live vital active lives. The ideal is for sighted and blind to work together to enrich the accomplishments of one another and not to compete on an very uneven playing field. As technology advances than the right move is to utilize the available resources to provide protection and enhanced audio information to adults and children who want to be contributors to their communities. Thank you for your serious considerations about the essential nature of the audible traffic signals.
