摘要

随着城市交通压力的不断增加，传统交通信号灯控制方式已难以满足实时高效的交通管理需求。本文提出一种基于LoRa通信技术的智慧城市交通信号灯自适应控制系统，通过低功耗广域网实现信号灯与传感器之间的实时数据传输，结合交通流量动态调节信号灯周期，实现交通流的智能优化。该系统不仅提高了交通效率，减少了车辆等待时间，还增强了系统的扩展性和可靠性，为智慧城市交通管理提供了创新的解决方案。实验结果表明，系统在实际应用中表现出优越的性能和稳定性。

Abstract

As urban traffic pressure continues to increase, traditional traffic signal control methods can no longer meet the demands of real-time and efficient traffic management. This paper proposes an adaptive control system for smart city traffic signals based on LoRa communication technology. By using a low-power wide-area network, it achieves real-time data transmission between traffic signals and sensors, combined with dynamic adjustment of signal cycle based on traffic flow, to realize intelligent optimization of traffic flow. The system not only improves traffic efficiency and reduces vehicle waiting time, but also enhances the system's scalability and reliability, providing an innovative solution for smart city traffic management. Experimental results show that the system demonstrates superior performance and stability in practical applications.
