This work presents the development and construction of an adaptive street lighting system that improves safety at intersections, which is the result of applying low-power Internet of Things (IoT) techniques to intelligent transportation systems. A set of wireless sensor nodes using the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard with additional internet protocol (IP) connectivity measures both ambient conditions and vehicle transit. These measurements are sent to a coordinator node that collects and passes them to a local controller, which then makes decisions leading to the streetlight being turned on and its illumination level controlled. Streetlights are autonomous, powered by photovoltaic energy, and wirelessly connected, achieving a high degree of energy efficiency. Relevant data are also sent to the highway conservation center, allowing it to maintain up-to-date information for the system, enabling preventive maintenance.
本工作提出了一种自适应街灯系统的开发和构建，该系统通过将低功耗物联网 (IoT) 技术应用于智能交通系统，提高了交叉口的安全性。一组使用电气和电子工程师协会 (IEEE) 802.15.4 标准的无线传感器节点，具有额外的互联网协议 (IP) 连接功能，可测量环境条件和车辆过境情况。这些测量结果被发送到协调器节点，该节点收集并将其传递到本地控制器，然后做出决策，使路灯亮起并控制其照明水平。路灯是自主的，由光伏能源供电，并通过无线连接，实现了高度的能源效率。相关数据也被发送到高速公路养护中心，以便其为系统维护最新信息，实现预防性维护。
