| 摘 要： | 为提高道路危险路段运营安全水平,促使驾驶人主动降低车辆运行速度至安全范围,对比并优化了减速标线的形式及设计参数。依据人在动态环境下视错觉减速标线作用机理,对鱼刺形视错觉减速标线各设计参数进行分析和初选,并提出变间距减速标线相隔距离的计算方法。将不同设计参数进行组合,依据正交试验方案,利用仿真试验平台和实际道路试验,对比各种形式标线的实际减速效果。研究表明:不同设计参数的鱼刺形减速标线,其实际减速效果有很大差异,合理的参数设计方能产生良好的减速效果;与等间距标线相比,变间距减速标线的减速效果更优。

| Abstract: | In order to improve the level of operation security in dangerous road sections,the speed should be slowed down to a safe range.The forms and design parameters of the deceleration markings was compared and optimized.Based on the mechanism of optical illusion deceleration markings in dynamic environment,the parameters of the chevron markings were analyzed and the space calculation method was proposed.The different design parameters were combined together to execute the orthogonal experiment.The simulation tes... |
