Regular inspection of transportation assets is essential to ensure pavement markings and pavements remain in good, clean, and safe condition. Our previous MPC-funded project (Report No. MPC-668) demonstrated the strong potential of using artificial intelligence (AI) and mobile phone imagery to identify...
Existing bridge deterioration models rely on subjective national bridge inventory (NBI) condition ratings from visual inspections, which lack the objective assessments needed for informed repair and maintenance decisions. Non-destructive evaluation (NDE) tests, such as impact echo (IE), provide quantitative...
In recent years, transportation agencies have increasingly turned to machine learning (ML) to enhance the effectiveness of infrastructure asset management. However, limited local inventory data often hinders building accurate and reliable ML models. Additionally, data privacy and ownership concerns discourage...
Escherichia coli (E. coli) in stormwater is a significant environmental concern as it indicates potential contamination from fecal matter, raising risks for both human and aquatic health. Conventional stormwater best management practices are generally not effective at removing E. coli from stormwater...
There is increasing awareness among transportation professionals about the importance of incorporating social equity into their practices. While the transit sector has made notable progress, other areas, such as asset management, are still lagging in integrating social equity into decision making. This...
This report investigates the application of low-cost sensing technologies, including GPS, accelerometers, and smartphones, to monitor roadway pavement conditions in real time. By leveraging widely available sensors embedded in vehicles, this research demonstrates how machine learning models can detect...
Escherichia coli (E. coli) is often used as an indicator organism to quantify the microbial safety of natural water resources. E. coli in stormwater runoff can cause serious health risks in natural water bodies. Conventional stormwater best management practices are generally not effective at removing...
The maintenance and upgrade of infrastructure and buildings are critical for ensuring their performance, safety, and minimizing costs. However, inadequate planning and budget allocation, as well as resource constraints, often result in delayed maintenance, leading to costly interventions. To address...
Transportation asset management requires timely information collection to inform relevant maintenance practices. Traditional data collection methods often necessitate manual operation or the use of specialized equipment, e.g., light detection and ranging (LiDAR), which can be labor-intensive and costly...
This comprehensive report synthesizes findings from three distinct yet interrelated studies, each exploring the developing role of drones in the condition monitoring of multimodal transportation assets. The first study, a systematic literature review (SLR) on railway inspection and monitoring (RIM)...
