提出了一种基于交通量的隧道照明智能控制方法。选取了赤白隧道(位于吉林省中国境内)在不同天气条件下12天的监测数据作为案例分析。分析中使用的数据包括交通量、车速、发光二极管(LED)在最低亮度水平下工作的时间,以及两辆连续车辆之间的平均时间间隔。交通流分析表明,该隧道白天(上午7点)的交通量较大。至下午6时)夜间(凌晨12:00)交通量相对较低。至早上6:00和晚上7:00至凌晨12时)。因此,我们提出了一种区分昼夜运营策略的隧道照明控制方法。在白天,隧道区域的亮度取决于隧道外部的亮度、交通量和车速,而与车辆的存在无关。夜间隧道亮度控制采用车进灯亮、车出灯暗的控制方式,依赖于车辆的存在。
This paper presents an intelligent control method for tunnel lighting based on traffic volume. The monitoring data for a period of 12 days of the Chibai tunnel (located in the Jilin province of China) under different weather conditions was selected as the case study. The data used in the analysis included traffic volume, vehicle speed, the time of light-emitting diodes (LEDs) operating at their lowest luminance level, and the average time interval between two consecutive vehicles. The traffic flow analysis indicated that the tunnel has a relatively heavy traffic volume in the daytime (7:00 a.m. to 6:00 p.m.) and a relatively low traffic volume in the nighttime (12:00 a.m. to 6:00 a.m. and 7:00 p.m. to 12:00 a.m.). Thus, we propose a tunnel lighting control method that distinguishes day and night operational strategies. In the daytime, the luminance of tunnel zones depends on tunnel exterior luminance, traffic volume and vehicle speed regardless of vehicle presence. In the night, the “vehicle in, light brightens; vehicle out, light darkens” control method is adopted for the tunnel luminance, which depends on vehicle presence.
