高速公路路侧雾灯控制与设置技术

Control and Setting Technology of Roadside Fog Lamps on the Expressway

为提高高速公路雾区段路侧雾灯的行车诱导能力，减少交通事故率，分析雾灯控制策略，从雾灯纵向、横向选址与安装高度等角度，研究雾灯工程设计理论，最后针对雾灯亮度与直径，建立雾灯选型计算方法。论文提出的分级雾灯控制策略、纵向间距计算方法、雾灯高度计算公式与直径模型等雾灯控制与设置技术，应用于龙长高速公路k69＋202～k71＋020雾区段，利用车速与道路线形指标计算，得出雾灯纵向间距为25～35m，雾灯高度为120～130cm，雾灯直径选用168mm。结果表明，高速公路路侧雾灯控制与设置技术，为雾灯工程提供了定量计算方法，有助于提高雾灯工程的科学性与系统性。

In order to improve the travel inducing ability of roadside fog lamps in the fog area of expressway and reduce the accident rate, the fog lamps control strategies were analyzed. Then the design theory of fog lamps was studied, including the vertical and transversal location, and the setting height. Finally, the rational calculation method for choosing fog lamps physical parameters was put forward, which explained how to select the luminance and diameter. The control and setting technology which was bought forward by the thesis, such as control strategy, vertical spacing, height and diameter calculation models, were applied in k69 ＋ 202 to k71 ＋ 020 fog area of Long Chang Expressway. With speed and highway alignment indexes calculation, we get the fog lamps vertical spacing as 25 to 35 m, the fog lamps height as 120 to 130 cm, the fog lamps diameter as 168 mm. The results indicate that, the control and setting technology of roadside fog lamps provide a quantified computing method for us, which will promote the scientific and systematic features of fog lamps projects.
