Automatic Inspection and Evaluation System for Pavement Distress

IEEE Transactions on Intelligent Transportation Systems, 2022
Pavement distress detection is of significance for road maintenance and traffic safety. Manual pavement distress detection suffers from high workloads, inefficiency, low accuracy, and high cost. To replace the manual operations in the pre-filling detection with the aim to improve efficiency and reduce cost, this paper proposes a three-stage automatic ...

Wavelet-Based Pavement Distress Classification [PDF]

Transportation Research Record: Journal of the Transportation Research Board, 2005
A two-step method–-wavelet transform followed by Radon transform–- is proposed for pavement distress classification. First, a pavement image is decomposed into different frequency subbands by wavelet transform. Distress is transformed into the high-amplitude wavelet coefficients, which are referred to as the details, in the high-frequency subbands. The

Identification of Pavement Distress in Kentucky [PDF]

, 2006
In Kentucky, the roads are comprised primarily of two types of pavement. The first being Portland Cement Concrete (PCC) a rigid pavement, and the other is Asphaltic Concrete (AC), a flexible pavement. There is a noticeable difference in their appearance, ride, cost and performance.

Pavement distress detection and severity analysis

SPIE Proceedings, 2011
Automatic recognition of road distresses has been an important research area since it reduces economic loses before cracks and potholes become too severe. Existing systems for automated pavement defect detection commonly require special devices such as lights, lasers, etc, which dramatically increase the cost and limit the system to certain ...

Automatic pavement distress detection system

Information Sciences, 1998
Abstract Statistics published by the Federal Highway Administration indicates that maintenance and rehabilitation of highway pavements in the United States requires over $17 billion a year. Conventional visual and manual pavement distress analysis approaches that the inspectors traverse the roads, stop and measure the distress objects when they are ...

Automatic inspection of pavement cracking distress

SPIE Proceedings, 2005
We present an image processing algorithm customized for high-speed, real-time inspection of pavement cracking. In the algorithm, a pavement image is divided into grid cells of 8×8 pixels, and each cell is classified as a noncrack or crack cell using the grayscale information of the border pixels. Whether a crack cell can be regarded as a basic element (

Effects of autonomous vehicles on pavement distress & road safety and pavement distress optimization

2021
The commercial application of automation technology in passenger and freight transport will bring positive revolutionary changes in transportation mobility. Despite having more advantages, automation in trucking technology has some detrimental effects on the performance of asphalt pavement and highway safety.

Pavement Distresses at Intersections

1995
Asphaltic concrete pavements at intersections and their approaches, where traffic is required to stop and start, exhibit several types of distress. Among the more prominent forms of these distresses are deep rutting, pushing and shoving, and severe wash boarding.
