A study on the method to estimate the road surface condition by utilizing the probe date

Abstract

In the snowy region, frequent existence of slippery condition brings driver to the highly strained situation in driving. In this study, detailed data from the vehicle is used to detect the road surface condition. After the accuracy of detailed data is confirmed, trial test that the experimental car runs in the field is conducted to understand the slipperiness of the road condition. Result shows that the locations of the slippery road condition cover all of the location of ABS detection, and there are many locations detected as the slippery road condition compared to the location of ABS detection.
