– At signalized intersections with heavy traffic, illuminated pedestrian crossings are applied for pedestrians to cross safely. At this stage, the green light is activated according to predefined times or signals from Accessible Pedestrian Signals (APS). Thanks to the pedestrian signals, the system activates only when there are pedestrians, and the flow of traffic accelerates as the vehicles do not have to stop when there are no pedestrians. APS are devices that give audible, vibrating and visual warnings so that all pedestrians can cross safely. An APS is a device that conveys information about pedestrian timing in a non-visual form, such as audible tones, spoken messages, or vibrating surfaces. The purpose of the signal pedestrian signals is to inform the intersection control device by detecting pedestrians on the highway section where the drivers are traveling at high speed, where there are heavy vehicle crossings and where there is no over and underpass facilities, and to make the transportation easier for the pedestrian to pass. In this study, it is aimed to design an APS at signalized intersections by using piezoelectric sensors. It is aimed to develop a completely domestic design by investigating the benefits, deficiencies, applicability and contributions of the planned system compared to the existing APS.
