An Evaluation Method of Visual-audiovisual Interventions Effectiveness for Sharp Bends on Mountainous Roads Based on Driving Simulation Tests
摘要
Abstract
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.关键词
