Abstract
Recently cars are been equipped with intelligent systems aiding safe driving. However a large percentage of traffic accidents between human and automobile happen on crosswalk. Intelligent functions from road side are also indispensable in order to make crosswalk safer. We propose a quiet navigation system for safe crosswalks by parametric speakers in order to allow pedestrians to safely cross streets for 24 hours and to find an easy way to their destination. In this paper we examine different types of new parametric speakers comparing them with regular traffic signal loudspeakers and propose a useful type of the speakers.
