Abstract

Smart cities need “intelligent” infrastructures designed or managed bearing in mind crucial characteristics, such as sustainability, efficiency, safety, and resiliency. Several solutions can be adopted, but the key factor for the suc-cess of the solution selected is its ability of improving the management process. The objective of the study described in this paper is to develop a solution that can be used to make smarter the road pavement monitoring and maintenance. In particular, a Non-Destructive Test (NDT)-based method is presented and ap-plied aiming at extracting crucial information about the Structural Health Status (SHS) of the monitored road pavement. Results show that the method is able to recognize the presence and the growing of induced cracks using meaningful features extracted from the vibro-acoustic signatures (acoustic signals) of the road pavement loaded by a light vehicle. The abovementioned features can be used to build innovative P-F curves able to improve the road pavement man-agement process.

... Finally, simulations showed that such a platform could provide an escape route from a traffic management perspective in case of an emergency [12]. Despite the limits coming from the large quantity of data that must be managed, an additional case study of a park in Reggio Calabria (Italy) highlights the importance that similar devices have in an SRE, not only for vehicle circulation but also for infrastructure monitoring [13], considering that this kind of survey could guarantee relevant cost and time savings compared to test-based and destructive methods.

Transport engineering has recently undergone several significant changes and innovations, one of which is the appearance and spread of autonomous vehicles; with this technology becoming more common and ordinary by the day, it is now necessary to implement some systems and contexts to facilitate autonomous vehicle operations. Consequently, a different perspective is now arising when dealing with road infrastructures, aiming to simplify and improve efficiency and maintenance of the existing roads, increase the life cycle of newly built ones, and minimize the economic and financial impact at the same time. Roadway pavements are one of the primary factors affecting vehicle operations; over time, this distinctive aspect has gone through various mechanical and physical changes due to the adoption of new materials or design methods. Consequently, to the spread of autonomous vehicles, scientific research has begun to study and develop systems to make road pavements and platforms not exclusively aimed at bearing loads, but rather at considering them as a means of communication and information exchange, if not even as a source of energy. This new approach introduces the so-called "Smart Roads," i.e., road infrastructures capable of communicating with vehicles and self-monitoring fundamental perspectives concerning driverless vehicles and the roadway platform life cycle. This paper examines the characteristics of Smart Roads, considering their broad field of application and their potential advantages and drawbacks. This paper also pursues the objective of describing the global vision, the possible future direction of these innovations concerning the automotive and transport industries, and a particular focus on infrastructures and roadways.

Potentialities of merging contact and noncontact measurement techniques for structural analyses are studied in this paper, to explore limits and advantages of classical and innovative techniques (accelerometers, Laser Doppler Vibrometer and microflowns pressure-velocity probes). The analysis refers to a previous experimental campaign, devoted to a specific test case in a modal analysis environment; this appears as a suitable and representative field of application for the goal of highlighting possible correlations to the benefit of a robust comparison among resulting indications coming from different transducers. Methodological suggestions, addressing future and more focused measurement campaign, post-processing algorithms and optimization procedures are provided in this paper. They will be used also for defining a more systematic experimental campaign to be carried in order to identify possible guidelines for both fusion of sensor indication and more complex structural characterization.

The current methods that aim at monitoring the structural health status (SHS) of road pavements allow detecting surface defects and failures. This notwithstanding, there is a lack of methods and systems that are able to identify concealed cracks (particularly, bottom-up cracks) and monitor their growth over time. For this reason, the objective of this study is to set up a supervised machine learning (ML)-based method for the identification and classification of the SHS of a differently cracked road pavement based on its vibro-acoustic signature. The method aims at collecting these signatures (using acoustic-sensors, located at the roadside) and classifying the pavement’s SHS through ML models. Different ML classifiers (i.e., multilayer perceptron, MLP, convolutional neural network, CNN, random forest classifier, RFC, and support vector classifier, SVC) were used and compared. Results show the possibility of associating with great accuracy (i.e., MLP = 91.8%, CNN = 95.6%, RFC = 91.0%, and SVC = 99.1%) a specific vibro-acoustic signature to a differently cracked road pavement. These results are encouraging and represent the bases for the application of the proposed method in real contexts, such as monitoring roads and bridges using wireless sensor networks, which is the target of future studies.

Modern society faces serious problems with transportation systems, including but not limited to traffic congestion, safety, and pollution. Information communication technologies have gained increasing attention and importance in modern transportation systems. Automotive manufacturers are developing in-vehicle sensors and their applications in different areas including safety, traffic management, and infotainment. Government institutions are implementing roadside infrastructures such as cameras and sensors to collect data about environmental and traffic conditions. By seamlessly integrating vehicles and sensing devices, their sensing and communication capabilities can be leveraged to achieve smart and intelligent transportation systems. We discuss how sensor technology can be integrated with the transportation infrastructure to achieve a sustainable Intelligent Transportation System (ITS) and how safety, traffic control and infotainment applications can benefit from multiple sensors deployed in different elements of an ITS. Finally, we discuss some of the challenges that need to be addressed to enable a fully operational and cooperative ITS environment.

This study presents a surface sensing approach for detection of bottom-up cracking in asphalt concrete (AC) pavements. The proposed method was based on the interpretation of compressed data stored in memory cells of a self-powered wireless sensor (SWS) with non-constant injection rates. Different 3D finite element (FE) models of an AC pavement were developed using ABAQUS to generate the sensor output data. A realistic dynamic moving load was applied to the surface of the pavement via DLOAD subroutines developed by FORTRAN. A network of sensing nodes was placed at the top of the AC layer to assess their sensitivity to the progression of bottom-up cracks. Several damage states were defined using Element Weakening Method (EWM). A linear-viscoelastic behavior was considered for the AC layer. In order to detect the damage progression, several damage indicator features were extracted from the data acquisition nodes. The damage detection accuracy was improved through a data fusion model that included the effect of group of sensors. The proposed fusion model was based on the integration of a Gaussian mixture model (GMM) for defining descriptive features, different feature selection algorithms, and a robust computational intelligence approach for multi-class damage classification. Furthermore, an uncertainty analysis was carried out to verify the reliability of the proposed damage detection approach. The results indicate that the progression of the bottom-up cracks can be accurately detected using the developed intelligent self-powered surface sensing system.

With the current changes in the automotive industry, vehicles need more and more advanced sensors for control, safety, monitoring, perception, and operation. With the current technological advancements, our cars are becoming more computers on wheels. There are more than one hundred sensors in a vehicle that many of them have the potential to be replaced with nanogenerators (NGs)-based self-powered sensors. In this article, we aim to investigate and propose self-powered sensors for different sensing applications in vehicles. Furthermore, we discuss how leveraging nanogenerators can be beneficial in bolstering intelligent transportation systems. Several conceptual ideas and designs for self-powered sensors in automotive-related systems are presented and discussed based on the current status of research in this area. The importance of self-powered sensors in vehicles are further elaborated and the energy harvesting potential of nanogenerators are shown for a few vehicle systems. Challenges, design concerns and the future impacts of self-powered sensing in automotive and traffic monitoring systems are fully discussed. It is delineated how the application of nanogenerators could accelerate the realization of fully smart vehicles and intelligent transportation.

Structural health monitoring can benefit transportation infrastructures in terms of pavement management systems and risk management. In this study, a new, non-destructive, acoustic-based method for assessing and monitoring the structural health status (SHS) of road pavements along their operational life is presented. In order to validate the proposed method, an experimental investigation was carried out. The acoustic response of an asphalt concrete road pavement following a proper mechanical excitation (hereafter named acoustic signature) was recorded and analysed. A specifically designed microphone-based electronic system was set up and applied. The acoustic responses were analysed in the time and frequency domain. An integrated system, including the power supply, the abovementioned system, and data transmission equipment was set up and applied as a part of a research project, to collect data and extract features and information valuable to different stakeholders. Experimental results show that the proposed system is able to detect the change of the acoustic signature of the infrastructure asset over time using a small number of meaningful features extracted by clustering techniques. Consequently, it can be used to monitor the SHS of road pavements by detecting the onset of cracks, and keeping under observation their evolution over time. Keywords: Acoustic signature, intelligent structural health monitoring, feature-based hierarchical clustering

Transportation systems are gradually changing. Innovative solutions are provided by automotive industries, construction firms, computer-aided pavement management systems, sensor-based structural health monitoring (SHM) systems, and international regulations. This calls for efforts and studies aiming at finding a trade-off between the ever-growing request of innovation (smart cities), and the never-ending depletion of resources and energy. Energy savings in road infrastructures can be pursued through: 1) construction process optimization; 2) traffic management improvement; 3) vehicle optimization; 4) recycling and reuse of construction materials; 5) innovative materials; 6) energy harvesting; 7) smart roads; 8) maintenance and rehabilitation optimization through SHMmethods and technologies. Theobjective of the study is to set up an innovative SHM method aiming at achieving energysavings in transportation in terms of Pavement Management System (PMS) optimization.The new method here setup was implemented through an experimental investigation. Amicrophone was placed on different road pavements, impulse loads were produced by aLight weight Deflectometer, LWD, and vibro-acoustic signals were recorded and analyzedin the pursuit of assessing the structural condition of the pavement. Using this knowledge toimprove the management process of transportation infrastructures, it is expected that safer,more resilient, and less energy-consuming assets will be provided.

The highway network of a country forms the backbone of its economy and represents a huge investment in millions of dollars that allows for the safe and efficient movement of people and goods. Economically feasible and technically sound decisions on design, construction, maintenance, rehabilitation, and reconstruction of highway pavements are crucial for preserving the highway network in an acceptable condition. The economic prosperity of a country is strongly associated with the relative size and physical condition of its road network, which is the most important component of its transportation infrastructure (Hudson et al., 1997). High paved road density values in Km per million inhabitants (Queiroz et al., 1994; Mobility, 2001; Uddin, 2002a) are reported for industrialized countries (examples: 12,517 for the United States; 9,330 for the European Union of Western European countries; 9,200 for Japan; and 7,880 for Central and Eastern European countries). Comparatively low values of this important economic development indicator are observed in developing countries (examples: 104 for Afghanistan; under 200 for China and India; 310 for Nigeria; and 763 for Brazil). These trends show that new construction and upgrade road projects consume most road funds in many developing countries, and more funds are allocated in industrialized nations to maintenance, rehabilitation, and preservation of the existing pavement assets. As competition for funding among different sectors of the economy and society has grown, there is a critical need to implement modern management and systems engineering tools to assist decision makers for cost-effective and longer lasting pavement construction and effective use of funds for timely maintenance to preserve the condition and prolong the life of pavement assets.

The performance of railway tracks can be assessed by separately applying different approaches, such as reliability, availability, maintainability, and safety (RAMS) and lifecycle costing (LCC). Results of these approaches are not comprehensive because RAMS management lacks an LCC perspective and balance, whereas LCC develops an economic analysis but does not address specific issues of railway performance. Based on these considerations, this study defines a key performance indicator (KPI) for railway tracks as merging the LCC and RAMS approaches at a given time. Innovative algorithms are set up for LCC, RAMS, and their relationship in the definition of KPI. Algorithms are applied to two different track alternatives (ballasted and ballastless), and the KPI trend over time is assessed. Case study results show that the KPI of ballasted tracks is higher in the short-term, whereas the slab track performs better in the long-term. The trend of KPI for the two solutions under investigation shows that the breakeven point depends on traffic and speed in the railway lines. The method setup as well the results obtained contribute to the body of knowledge of construction engineering because: (1) the equations set up allow deriving agency-based algorithms through calibration; (2) the model set up and implemented allows agencies to handle basic technical instances (e.g., RAMS) and lifecycle-related issues (in which sustainability is considered) in a synergistic and quantitative way; and (3) the previously mentioned KPI has the potential to quantitatively affect decision making across the entire cycle of life (design, maintenance, and renewal).

An important objective of acoustic emission (AE) non-destructive monitoring is to accurately identify approaching critical damage and to avoid premature failure by means of the evolutions of AE parameters. One major drawback of most parameters such as count and rise time is that they are strongly dependent on the threshold and other settings employed in AE data acquisition system. This may hinder the correct reflection of original waveform generated from AE sources and consequently bring difficulty for the accurate identification of the critical damage and early failure. In this investigation, a new qualitative AE parameter based on Shannon's entropy, i.e. AE entropy is proposed for damage monitoring. Since it derives from the uncertainty of amplitude distribution of each AE waveform, it is independent of the threshold and other time-driven parameters and can characterize the original micro-structural deformations. Fatigue crack growth test on CrMoV steel and three point bending test on a ductile material are conducted to validate the feasibility and effectiveness of the proposed parameter. The results show that the new parameter, compared to AE amplitude, is more effective in discriminating the different damage stages and identifying the critical damage.

This project deals about the Intelligent Transport System .that means the advanced mode of transportation systems that include many software's that are helpful for the safe transportation, to relieve traffic congestion, to reduce air pollution, to increases energy efficiency and to promote the development of the related industries. Intelligent transportation systems (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. Although ITS may refer to all modes of transport, EU Directive 2010/40/EU defines ITS as systems in which information and communication technologies are applied in the field of road transport, including infrastructure, vehicles and users, and in traffic management and mobility management, as well as for interfaces with other modes of transport.

The texture of road surfaces has a fundamental influence on the main technical and economical aspects of road transport systems. However, the logical structure and computation techniques for defining and measuring the indices are still somewhat heterogeneous. It is therefore desirable to obtain a unified interpretation of all the indices. The paper establishes the links between the functional performances and the texture indices.

The life cycle of hot mix asphalt (HMA) depends on the material density. Bulk specific gravity and air void content are crucial factors for quality control and quality assurance (QC/QA) procedures used to evaluate contract specifications. Densities measured in the laboratory are reliable and accurate but are obtained very slowly. On-site measurements are made using non-nuclear portable devices and are often considered biased and unreliable. The object of this work was to evaluate a proposed theoretical framework for interpreting in-lab and on-site measurements and to propose strategies for using non-nuclear portable devices in QC/QA. A decrease in porosity yielded in-lab specific gravities that converged. In contrast, due to the high dielectric constant of water the divergence of in-site measures was observed. A conceptual framework and two practical equations are provided.
