TL;DR: The results are promising, and the information extracted using the proposed pothole detection method can be used, not only in determining the preliminary maintenance for a road management system and in taking immediate action for their repair and maintenance, but also in providing alert information of potholes to drivers as one of ITS services.
Abstract: Potholes can generate damage such as flat tire and wheel damage, impact and damage of lower vehicle, vehicle collision, and major accidents. Thus, accurately and quickly detecting potholes is one of the important tasks for determining proper strategies in ITS (Intelligent Transportation System) service and road management system. Several efforts have been made for developing a technology which can automatically detect and recognize potholes. In this study, a pothole detection method based on two-dimensional (2D) images is proposed for improving the existing method and designing a pothole detection system to be applied to ITS service and road management system. For experiments, 2D road images that were collected by a survey vehicle in Korea were used and the performance of the proposed method was compared with that of the existing method for several conditions such as road, recording, and brightness. The results are promising, and the information extracted using the proposed method can be used, not only in determining the preliminary maintenance for a road management system and in taking immediate action for their repair and maintenance, but also in providing alert information of potholes to drivers as one of ITS services.

TL;DR: In this paper, a literature review on pavement distresses and related detection methods is presented, and a gap analysis is conducted which is concluded that in particular the distresses related to pavement microtexture need serious additional research in order to be implemented in a cost-effective fashion.
Abstract: In recent years, extensive research has been conducted on pavement distress detection. A large part of these studies applied automated methods to capture different distresses. In this paper, a literature review on the distresses and related detection methods are presented. This review also includes commercial solutions. Thereafter, a gap analysis is conducted which is concluded that in particular the distresses related to pavement micro-texture need serious additional research in order to be implemented in a cost-effective fashion. Depth-related distresses are detectible fairly well, but rely on expensive tools.

In this respect, the application was comparable to the area-scan and line-scan cameras. These are to be used for identification of patches, among cracks and potholes, as these three types of distresses have clear 2-D characteristics. Prasanna, Dana, Gucunski, and Basily (2012) conducted video imaging for identifying cracks. A comparable method was developed by Radopoulou and Brilakis (2015) who used the video images from already installed parking cameras on passenger cars. Also, potholes detection on the basis of video cameras has been researched (Koch & Brilakis, 2011). Just as the patch detection as described before, rear view parking cameras integrated in modern passenger cars are used for data collection. A fish-eye lens is installed in order to widen the angle of view of the camera. Dash cameras (also called black-box cameras) were studied by Hadjidemetriou et al. (2016) for detecting patches, as high resolution is not a prerequisite....

TL;DR: In this paper, the authors investigate and analyze pothole detection methods which have developed and propose a potential direction of developing a pothhole detection method to accurately and efficiently detect potholes.
Abstract: As one type of pavement distresses, potholes are important clues indicating structural defects of the asphalt road, and accurately detecting these potholes is one of important tasks for determining proper strategies of asphalt-surfaced pavement maintenance and rehabilitation. However, manually detecting and evaluating methods are expensive and timeconsuming. Thus, several efforts have been made for developing a technology which can automatically detect and recognize potholes, which may contribute to improvement of survey efficiency and pavement quality through prior investigation and immediate action. In this study, we investigate and analyze pothole detection methods which have developed and propose a potential direction of developing a pothole detection method to accurately and efficiently detect potholes.

TL;DR: Current approaches for using smartphones for road surface anomaly detection are reviewed and compared, and further opportunities for research using smartphones in road surface anomalies detection are highlighted.
Abstract: Road surface monitoring is a key factor to providing smooth and safe road infrastructure to road users. The key to road surface condition monitoring is to detect road surface anomalies, such as potholes, cracks, and bumps, which affect driving comfort and on-road safety. Road surface anomaly detection is a widely studied problem. Recently, smartphone-based sensing has become increasingly popular with the increased amount of available embedded smartphone sensors. Using smartphones to detect road surface anomalies could change the way government agencies monitor and plan for road maintenance. However, current smartphone sensors operate at a low frequency, and undersampled sensor signals cause low detection accuracy. In this study, current approaches for using smartphones for road surface anomaly detection are reviewed and compared. In addition, further opportunities for research using smartphones in road surface anomaly detection are highlighted.

TL;DR: The dynamic optimization-based method, which was previously used for segmenting low signal-to-noise ratio (SNR) digital radiography images, outperforms the other five methods based on the authors' scoring measure.
Abstract: Image segmentation is the crucial step in automatic image distress detection and classification (e.g., types and severities) and has important applications for automatic crack sealing. Although many researchers have developed pavement distress detection and recognition algorithms, full automation has remained a challenge. This is the first paper that uses a scoring measure to quantitatively and objectively evaluate the performance of six different segmentation algorithms. Up-to-date research on pavement distress detection and segmentation is comprehensively reviewed to identify the research need. Six segmentation methods are then tested using a diverse set of actual pavement images taken on interstate highway I-75/I-85 near Atlanta and provided by the Georgia Department of Transportation with varying lighting conditions, shadows, and crack positions to differentiate their performance. The dynamic optimization-based method, which was previously used for segmenting low signal-to-noise ratio (SNR) digital radiography images, outperforms the other five methods based on our scoring measure. It is robust to image variations in our data set but the computation time required is high. By critically assessing the strengths and limitations of the existing algorithms, the paper provides valuable insight and guideline for future algorithm development that are important in automating image distress detection and classification.

TL;DR: In this article, a vibration-based pavement evaluation system was developed for preliminary evaluation of pavement conditions based on the mechanical responses of the testing vehicle when driving on the pavement, and a testing system was set up and data were collected to validate the measurement concept, which indicated that there is a good correlation between vibration responses and the pavement conditions.
Abstract: Proper evaluation of pavement conditions provides important decision-support to implement preventative rehabilitation. Traditional method for pavement inspection relies on human observation that has low-efficiency and is subjective to errors. More recent tool for pavement distress inspection utilizes digital video and image analyses to record and identify the pavement surface conditions. This significantly increased the inspection efficiency and reliability. However, the video based system requires large storage space and extensive computation for image processing. It is also difficult to automate the pavement rating. This paper describes the use of recent data acquisition hardware to develop a vibration-based system for preliminary evaluation of pavement conditions. In analogy to the video record which looks at the surface of the pavement, the vibration-based system feels the ground conditions based on mechanical responses of the testing vehicle. The interactions of the ground and vehicle can be described by a model where vehicle is under random force excitations. The distresses of the pavement, including the cracks and surface rutting, impose impacting forces on the vehicle. The frequency and magnitude of the forces are dependent on the extent and magnitude of pavement distresses. On the other hand, the pavement surface conditions can be estimated from the recorded responses of the testing vehicle when driving on the pavement. A testing system was set up and data were collected to validate the measurement concept. Analyses of the testing data indicate that there is a good correlation between vibration responses and the pavement conditions. Factors such as the driving speed and the transition of vehicle motion were investigated. The vibration-based pavement evaluation system described in this paper has the advantage of small storage requirement, cost-effective and amenable for automatic real-time data processing. While this system does not provide the complete details of distress characteristics as by video-based system, it can be an inexpensive tool for routine inspections to provide preliminary evaluation of pavement conditions.

TL;DR: This work examines algorithms for segmenting pavement images and evaluates their effectiveness in separating the distresses from the background, and indicates that the relaxation and regression thresholding methods consistently outperform the other methods.
Abstract: Collection and analysis of pavement distress data is an important component of any pavement-management system. Various systems are currently under development that automate this process. They consist of appropriate hardware for the acquisition of pavement distress images and, in some cases, software for the analysis of the collected data. An important step in the automatic interpretation of images is segmentation, the process of extracting the objects of interest (distresses) from the background. We examine algorithms for segmenting pavement images and evaluate their effectiveness in separating the distresses from the background. The methods examined include the Otsu method, Kittler’s method, a modified relaxation method, and a method is based on a threshold estimated by regression analysis. Comparison of the algorithms on a data set of asphalt pavement images indicates that the relaxation and regression thresholding methods consistently outperform the other methods. The regression thresholding method has the potential to become the method of choice due to its computational advantage over the relaxation method.
