MPC Research Reports
View AllTransportation 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)... U.S. residents across many regions continue to face episodes of poor air quality due in part to pollution and emissions from the transportation sector. Strategies to encourage travel behavior changes and reduced driving during such events may or may not be effective. To illuminate how area-wide air pollution... This report documents the effort to develop a practical relation between the cracking tolerance index and portions of the dynamic modulus curves of asphalt mixtures. A review of practices used to create asphalt mixtures' dynamic modulus master curves, based on NCHRP reports and other relevant literature... Transportation planning, traffic monitoring, and traffic safety analysis require detailed information about pedestrian volumes, but such data are usually lacking. Fortunately, recent research has demonstrated the accuracy of pedestrian volumes estimated from push-button data contained within high-resolution... This research explores the influence of thermo-mechanical beneficiation methods on the physicochemical characteristics and reactivity of fly ashes disposed of in landfills (LFAs) obtained from power plants in Wyoming and Colorado, USA. An in-depth assessment was conducted on the mechanical and performance... A community is considered walkable if it is easy and safe for pedestrians to walk for recreation and exercise and to destinations such as schools, stores, parks, and post offices. A walkable community encourages the safe use of existing infrastructure while expanding transportation options for users... This study evaluated connected and autonomous vehicle (CAV) crash reporting practices across the United States, emphasizing the importance of standardized reporting and legislation for the safe deployment of CAVs on public roads. Through a survey of state transportation officials and a review of current... The transportation experiences of people with disabilities have improved since the passing of the Americans with Disabilities Act (ADA) in 1990. Despite progress, many aspects of the current transportation system still limit people with disabilities from traveling safely and efficiently. Moreover, transportation... Construction projects require long hours where workers are subjected to intensive tasks such as hard manual labor, heavy lifting, and constrained working postures. Among the physiological metrics, heart rate (HR) is reported to be a good indicator of physical stress and workload. HR forecasting models... |
