Sinalizador auxiliar de trânsito inteligente SAT-IN

Abstract

Traffic circulation on narrow urban roads, especially in tourist cities such as the municipality of Tibau do Sul/RN and, in particular, the district of Pipa, has become an increasing challenge within the context of contemporary urban mobility. The intense daily flow of vehicles and pedestrians, combined with the physical limitations of road infrastructure and the lack of efficient signaling systems, results in frequent traffic conflicts, recurring congestion, increased collective stress, and higher rates of traffic accidents. The unpredictability of traffic behavior in such environments highlights the need for technological solutions capable of operating adaptively according to real-time traffic conditions. In response to this problem, this project proposes the development of the Intelligent Auxiliary Traffic Signaling System (SAT-IN), an electronic device designed to function as a complementary traffic signaling system, operating in a dynamic and responsive manner. Unlike conventional traffic lights, which rely on fixed time cycles and do not account for instantaneous variations in vehicle flow, SAT-IN is based on the use of presence and motion sensors integrated with an Arduino microcontroller, enabling real-time detection of vehicular circulation at critical points along the roadway. Based on the acquisition and processing of sensor data, the system is able to activate visual warning signals directed at drivers, informing them about road occupancy and potential trajectory conflicts before entering narrow or low-visibility sections. In this way, SAT-IN aims to promote a more homogeneous distribution of vehicle flow, contributing to improved traffic fluidity and enhanced road safety through continuous adaptation of signaling according to observed demand.
