Road networks play an important role in economic prosperity and wellbeing. The transportation efficiency and driving safety of road networks are significantly affected by various damages and defects on the road surface, but it can take weeks or even months before related government departments become aware of such road conditions under current approaches, making timely maintenance and asset management difficult. In this paper, a methodology of using networked sensor-enhanced vehicles is proposed for effective and efficient monitoring and assessment of road surface condition, and a low-cost sensing device is developed based on a 6-axis accelerometer/gyroscope. By analyzing the data collected from road tests, a method is developed for identifying bumps and potholes, the two major types of road defects. Different encounter situations between the wheels and a road defect is investigated in terms of the number and the location of the wheels. Moreover, the effect of driving speed on the data is studied. It is expected that the proposed technology can provide both qualitative and quantitative information about the road surface condition and thus enable timely maintenance to improve transportation efficiency and driving safety.
