Research On Influence Of Colored Asphalt Pavement On Driving Safety Of Highway

While China's highway mileage and number of drivers are growing rapidly,traffic accidents are frequent.In order to reduce the risk of accidents,researchers launched a series of safety studies and proposed relevant countermeasures.And with the wide application of colored asphalt pavement,it is necessary to study its safety.This paper studies the influence of the highway colored asphalt pavement and its optimal design,aiming to improve the safety and comfort of driving.Firstly,this paper analyzes the characteristics of the driver and the theories of highway colored asphalt pavement,to lay the theoretical foundation for the following.Secondly,analyze the features of accidents in highway accident-prone areas,also the problems and the influencing factors in color pavement's design.It is concluded that the scientific and effective construction of colored asphalt pavements in accidentprone sections has practical significance for safe driving.Then,the heart rate growth rate,LF/HF and HFnorm indicators of ECG signals were measured by simulation experiments on the downhill section of the villager of the stone slab of the Miyu Highway high-speed stone tablet.The results show that the color of asphalt pavement on the long downhill of the highway should give priority to the red and yellow colors,followed by red and yellow.Finally,according to the psychology SD evaluation method,use the SPSS software to analyze the principal components of the collected data.The results show that: at the highway tunnel entrance,the driver is more likely to accept red color for the road surface;for the color of the road surface pattern,the driver prefers to strips and blocks,blocks,bars,rectangles,etc.In summary,it is advisable to pave the red asphalt pavement with the best comfort and safety at the tunnel entrance.The research's conclusions have a certain guiding effect on the design of highway colored asphalt pavement and improvement of driving safety,especially at the highway accident-prone areas.
