摘要：

为探索成本控制下以艺术介入提升道路照明安全的路径，以习水产城大道照明设计为例，运用驾驶人视觉注意理论，根据道路空间围合场景、道路长度阈限，研究路侧灯杆色彩对驾驶员视疲劳的影响；研究发光二极管（LED）灯箱对雾天行车视觉诱导性、行人防侵犯安全和位置辨识的影响及道路照明方式、光源色温及显色指数对雾间夜间行车安全的影响；基于节能要求，提出全亮（上半夜）、深夜、雾天昼间、雾天深夜4种工作模式；项目建成后，通过分析实测数据及使用者主观评价，验证设计策略在全天候、全时段下的可靠性、有效性。结果表明：司机和行人对设计的独特性、夜间道路光环境安全性、路灯设施的视觉诱导性满意度较高；彩色灯杆能在一定程度上缓解司机视疲劳、提醒减速；灯箱对雾天夜间行车有视觉参照作用。

Abstract:

In order to improve road lighting safety through an artistry lighting design strategy with limited cost， with lighting design of Chancheng Avenue in Xishui county as an example， influence of lamppost color on drivers' fatigue was studied based on road space enclosed scene and road length threshold by using drivers' visual attention theory. Secondly， effects of LED light-boxes on visual guidance in foggy weather， pedestrian security， and location identification were explored， and influence of road lighting， light source color temperature， and color rendering index on foggy nighttime driving safety was studied. Then， four different working modes for full bright （from dusk till midnight）， mid-night， foggy daytime， and foggy nighttime were proposed based on energy-saving requirement. Finally， reliability and effectiveness of all-weather， all-time design strategy were verified through data measurement and user evaluation after project completion. The results indicate high satisfaction from drivers and pedestrians on the uniqueness of the design， safety of the nighttime road lighting environment， and visual guidance of lighting facilities. Colored lampposts relieve drivers' visual fatigue and remind them to reduce speed. Also， the light-boxes effectively provide visual reference for foggy nighttime driving.

Key words: traffic safety, road lighting, landscaplization, lamppost color, LED light-boxes, foggy weather
