为减少高速公路隧道照明能耗，有效降低隧道运营维护成本，将先进的信息技术发展成果应用到隧道智慧照明系统中，提出基于KNX技术的高速公路隧道智慧照明系统。首先，根据停车视距、设计时速、系统响应时间和行车过程等因素，制定出能够保障驾乘舒适度与行车安全的按需照明方案；然后，在充分利用现有监控系统的外场设施、通信设施及各种数据资源的基础上，引入KNXnet/IP路由器、车检器等设施，通过数据分析准确掌握隧道内车辆情况，实现按需照明；最后，以四川省经营性公路统计数据进行节能测算，节能效益良好。该系统符合智慧交通的发展趋势，既能够充分保证照明安全、提升节能水平，又在系统稳定性、扩展性和网络安全等方面具有优势。

To effectively reduce the energy consumption and operation costs of highway tunnel lighting, the advanced information technologies are applied to the tunnel smart lighting system of highway tunnels, and the highway tunnel smart lighting based on KNX technology is proposed. First, according to factors such as parking sight distance, design speed, system response time, and driving process, the "ondemand lighting" scheme is formulated to ensure driving comfort and driving safety. Second, on the basis of making full use of the surveillance system, communication system, and various data resources, KNXnet/IP routers, vehicle detectors, and other facilities are introduced to accurately grasp the situation of vehicles in the tunnel through data analysis, so as to achieve "ondemand lighting". Finally, according to the statistical data of operating toll highways in Sichuan Province, the energysaving benefit of this system is excellent. This system is in line with the development trend of smart traffic, not only can fully guarantee the lighting safety and improve the energysaving level, but also has advantages in system stability, scalability,  and network security.
