4)Utilization and Application of Probe Data to Road Maintenance and Management

Abstract

This project was conducted for the purpose of studying potential generation of data that can be utilized in road maintenance and management, as well as information useful in automated vehicle driving, such as information related to poor weather and road conditions, based on probe vehicle data. As probe vehicle data used for studies, we take up data that can currently be acquired, such as ABS, traction control systems, Electronic Stability Controls, and windshield wiper operation data, and data that may be acquired in the future, such as road grip level data and water film thickness estimates. By grasping the correlation between probe vehicle data and various meteorological data that can grasp the precipitation and organizing in along the same units for each category, we plan to consider the potential for data generation and the effectiveness of this data in automated driving support and road maintenance.
