道路草花景观对驾驶人员红灯敏感度的影响

近年来,随着对城市道路景观构建的重视,道路绿化、彩化景观愈发优美和引人注目。该文基于152份有效问卷,研究对比分析了3种道路灌-草层的绿化形式(绿篱式、50%草花覆盖式及100%草花覆盖式)对有驾驶经验的受访者红灯敏感度的影响。结果显示,相对于绿篱式道路绿化,草花式道路绿化会造成受访者红灯敏感度降低;女性比男性的红灯敏感度高,但更易受草花干扰;25—45岁年龄段受访者对红灯的敏感度和抗草花干扰能力比18—25岁及45岁以上受访者高;相对于偏好草花式绿化的受访者,偏好绿篱式绿化的受访者有更高的红灯敏感度和抗草花干扰能力。建议应尽量避免在事故易发地段大面积应用颜色艳丽的草花进行道路绿化。

Study on the influence of road herbal-flower landscape on the red light sensitivity of drivers

In recent years,with the emphasis on urban road landscapes,road greening has become more beautiful and eye-catching.Based on 152 valid questionnaires,we compared and analyzed three road greening forms of shrub-herb layer(hedge,50%herbal-flower cover and 100%herbal-flower cover)for red light sensitivity of respondents with driving experience.It was found that compared to hedge greening,herbal-flower greening could reduce the red light sensitivity of interviewees;females were more sensitive to red light than males,but more susceptible to herbal flower interference;25—45-year-old interviewees had highest red light sensitivity and resistance to herbal flower interference than 18—25-year-old interviewees and those aged over 45;interviewees who prefered hedge greening had higher red light sensitivity and resistance to herbal-flower interference than interviewees who prefered herbal-flower greening.The research suggests that large area of brightly colored herbal-flowers should be forbidden as much as possible in order to avoid accident.
