![]() The real-time detection of precursors to ground hazard triggering conditions. Will begin the second phase, which will use artificial intelligence (AI) to automate We will monitor for the development of such conditions over time and make predictionsĪfter the model is developed using data from the first phase of the project, the team Hazards, such as those that trigger landslides,” Rizos says. ![]() “These measurements will be used to develop a model correlating satellite imageryĪnd other geospatial information to conditions that are considered precursors to ground Working at a local site, the teamĬonducts ground measurements to investigate how satellite radar data can be used toĭetect and monitor moisture changes in the railway track and slopes, as well as smallĪnd large-scale deformations of the ground surface. ![]() Such as flooding, slope failures and rock falls. Seven sites around the world and classified them based on data for potential events, Rizos’ research team began by working with the FRA and Class I railroads to identifyĬandidate sites for satellite monitoring, such as where railroads have concerns ofĭerailment or right-of-way encroachment due to the stability of the track. Parameters to physical properties to see how that would allow us to predict change “At that point, we decided to look at railway track and the correlation of signal Identified a student who was excited to work with satellites and signal processing. His interest in the area began about seven years ago when he Imagery, coupled with recent advances in remote sensing, data collection and imageĪnalysis algorithms. Rizos explains that early detection and improved prediction of the risk potentialįor landslides and geotechnical failure is now feasible due to affordable satellite Time and are not predictive in nature by themselves. They also typically do not monitor the rate of change in conditions over Methods are deployed infrequently due to high costs and do not provide network-wide Positioning System, surveying and visual inspections, can disrupt operations. But conventional inspection and monitoring methods, such as Global Settlement and blockage from landslides, mudslides and rockslides, which can lead Of the track and stability of slopes in cuts and embankments are critical for preventing Inspection and monitoring are integral to the railway industry for ensuring serviceĬontinuity and maintaining the safety of operations. The $310,819 grant will develop techniques that use satellite radar imageryĪnd other geospatial data to monitor for precursors to hazardous ground conditions High Temperature Electrochemical Materials and Energy LabĬivil and Environmental Engineering Associate Professor Dimitris Rizos is working to improve the safety of railways worldwide through a three-year studyįunded by the Federal Railroad Administration (FRA).Center for Information Assurance Engineering.Center for Mechanics, Materials and Non-Destructive Evaluation.Multifunctional Materials and Structures.SAGE: Strategic Approaches to the Generation of Electricity.Molten Salt Thermal Properties Databases.Molten Salt Thermal Properties Working Group.Center for Rational Catalyst Synthesis (CERCAS).Aberration-Corrected Scanning Transmission Electron Microscopy Facility.Transfer and Current Students: Separate Application Scholarships.Transfer and Current Students: General Scholarship Application.Freshmen: Separate Application Scholarships.Freshmen: General Scholarship Application.
