The aim of this paper is to test the suitability of a smart traffic light request button, equipped with a contactless pedestrian detection and a green time extension for certain target groups. Within a preliminary analysis the primary factors hygiene, usability and comfort are considered. Based on this groundwork, a concept of a smart traffic light request button is developed, which includes a pedestrian detection with ultrasonic technology and the extension of the green light time via radio frequency identification. Furthermore, the technical implementation is finally composed in a drafted prototype. With the help of a sample group an experimental evaluation of the prototype is carried out. The evaluation results show, that the smart traffic light request button is widely accepted, and a benefit is generated for pedestrians. In addition, the hypothesis, which is developed in the preliminary analysis and assumes the benefit of a smart traffic light button, is confirmed by this evaluation.
