Abstract

Road surface monitoring is a significant issue in providing smooth road infrastructure for vehicles, and the key to road condition monitoring is to detect road potholes that affect driving comfort and transportation safety. This paper presents a simple, efficient, and accurate way to evaluate road service performance based on the acquisition of road vibration data by vibration sensors installed in vehicles. Inspired by the discrete fast Fourier transform, the vibration acceleration is processed, and the RMS value of vibration acceleration at 1/2 octave is calculated, after which the road vibration level is calculated. The vibration level is optimized according to the human body’s sensitivity to different frequencies of vibration, resulting in road service performance indicators that can reflect the human body’s real feelings. According to the road service performance index values on the road grading, combined with GPS data on the electronic map color block labeling, the results obtained for the road condition warning, road maintenance, driver route selection have an important significance.

Highlights

Some scholars have taken advantage of built-in accelerometers in mobile phones to measure road smoothness
Existing studies mostly utilize bicycles bound to smart phones to collect road vibration data, and the processing process mostly uses the time domain acceleration amplitude to judge, missing the impact of different vibration frequencies on road service performance [11,12,13,14]
A large number of psychological and physiological experiments have shown that many vibrations are harmful to the human body, and the degree of harm to people is related to the way the vibration is transmitted to people and the characteristics of the vibration itself. e approach vibration is transmitted to people can be divided into overall vibration and local vibration, and its evaluation criteria are different. e vibrations generated by driving on uneven surfaces of the road are transmitted to the car through the wheels and suspension, causing environmental vibrations that support the human body. e effect on the human body is the overall vibration, which is transmitted from the surface of the object to the human body
