基于驾驶模拟试验的山区公路急弯路段视听干预效用评估方法OA
An Evaluation Method of Visual-audiovisual Interventions Effectiveness for Sharp Bends on Mountainous Roads Based on Driving Simulation Tests
现有路段安全干预设施布设研究多聚焦于城市道路和高速公路场景,而针对山区公路急弯路段安全干预效用评估方法的研究则相对较少.为明确山区公路急弯路段不同安全干预方式的效用差异及布设依据,以重庆市永川S545急弯路段为原型搭建场景,并招募28名被试驾驶人开展驾驶模拟试验.选取红、黄、蓝、绿4种颜色的可变信息标志板(variable message sign,VMS)作为视觉干预方式,选取驾驶模拟器平稳状态噪声基础上增加8、11.5、15 dB车载抽象音作为听觉干预方式,设计单一与视听组合交叉试验,并提出干预设施前置距离计算模型.通过分析山区公路急弯路段的速度均值、加速度峰值及横向偏移率指标综合评估不同干预方式的效用.研究结果表明:设计速度为30 km/h时的山区公路急弯路段视觉干预与听觉干预前置距离分别设置为31.4 m和41.7 m;黄色VMS为最优单一视觉干预方式,速度均值、加速度峰值及横向偏移率降幅分别为22.3%、34.7%、58.4%;+11.5 dB为最优单一听觉干预方式,速度均值、加速度峰值及横向偏移率降幅分别为17.3%、38.5%、43.7%,单一视觉(黄色)或听觉(+11.5 dB)干预效果均较佳;黄色VMS+11.5 dB组合干预改善效果最佳且优于单一干预方式,速度均值降低26.0%、加速度峰值降低40.3%、横向偏移率降低66.9%,可推荐为山区公路急弯路段优先部署方案.
Existing research on the deployment of safety interventions primarily focuses on urban roads and high-ways.However,methods for evaluating the effectiveness of safety interventions at sharp bends on mountain roads remain limited.To clarify the effectiveness of different safety interventions and the basis for placement,a driving simulation scenario is established based on the S545 section in Yongchuan,Chongqing.Twenty-eight drivers are re-cruited to participate in the driving simulation tests.Variable message signs(VMS)in four colors:red,yellow,blue,and green—are selected as visual interventions.On the basis of the steady-state noise from the driving simulator,on-board warning sounds with increases of 8,11.5,and 15 dB are added as auditory interventions.Single-modality and audiovisual combination experiments are designed,and a model for calculating the distance for placing interven-tions is proposed.The effectiveness of different interventions is comprehensively evaluated by analyzing the aver-age speed,peak acceleration,and lateral deviation rate.The results indicate that,at sharp bends on mountain roads,the distances for placing visual and auditory interventions are 31.4 m and 41.7 m,respectively.The yellow VMS is the optimal single visual intervention,with reductions in average speed,peak acceleration,and lateral deviation rate of 22.3%,34.7%,and 58.4%,respectively.The 11.5 dB increase condition is the optimal single auditory interven-tion,with reductions in average speed,peak acceleration,and lateral deviation rate of 17.3%,38.5%,and 43.7%,re-spectively.Both the yellow VMS single visual intervention and the 11.5 dB auditory intervention yield good results.The yellow VMS and 11.5 dB combination intervention achieves the best effect,with reductions in average speed,peak acceleration,and lateral deviation rate of 26.0%,40.3%,and 66.9%,respectively.This combination interven-tion is superior to single interventions and is recommended as the preferred deployment scheme for sharp bends on mountain roads.
