City-Scale Digital Twin Framework for Flood Impact Analysis: Integrating Urban Infrastructure and Real-time Data Analytics
Published: 2025-03-17
Subjects: Computer Engineering, Environmental Engineering, Risk Analysis, Transportation Engineering
Urban areas are increasingly vulnerable to flooding due to climate change and rapid urbanization. Traditional mapping and decision-support tools lack the capability to integrate real-time data or analyze cascading disruptions across interconnected urban systems. Digital twins offer a promising solution by enabling real-time monitoring, simulation, and optimization of urban environments. This [...]
Understanding Flood Risk in Public Transit Systems: Insights from Accessibility and Vulnerability Analysis in Iowa
Published: 2025-03-14
Subjects: Civil and Environmental Engineering, Civil Engineering, Engineering, Geographic Information Sciences, Geography, Operations Research, Systems Engineering and Industrial Engineering, Risk Analysis, Spatial Science, Transportation Engineering
Flooding is a major challenge for urban transportation systems, hindering access to essential services and jobs, especially for vulnerable populations. This study examines the impact of large flood extents on public transportation in Johnson and Linn counties, Iowa, United States, focusing on flood-prone bus routes, reduced service frequency, and access to job locations. Using Geographic [...]
A GPR Based Non-destructive Approach to Monitor the Engineering Properties of Compacted Base Layer
Published: 2025-03-07
Subjects: Civil Engineering, Geotechnical Engineering, Transportation Engineering
Construction variability and isolated defects in base layer can be limiting factors in pavement’s service life. To control construction quality and implement an efficient quality management system, this study develops a quick, accurate, and simple non-destructive method using ground penetrating radar (GPR) to determine reliable values of in-place compacted base material properties, such as [...]
AI-Driven Decision-Making for Water Resources Planning and Hazard Mitigation Using Automated Multi Agents
Published: 2024-12-26
Subjects: Civil Engineering, Computational Engineering, Computer and Systems Architecture, Computer Engineering, Ecology and Evolutionary Biology, Education, Engineering, Environmental Engineering, Geotechnical Engineering, Higher Education, Hydraulic Engineering, Operations Research, Systems Engineering and Industrial Engineering, Risk Analysis, Scholarship of Teaching and Learning, Systems Engineering, Terrestrial and Aquatic Ecology, Transportation Engineering
This project simulates the Multi-Hazard Tournament (MHT) framework, a decision support system designed for the U.S. Army Corps of Engineers, using AI agents to enhance decisionmaking processes for flood mitigation and water resource management. The objective of the framework is to develop optimal strategies for protecting water resources, habitats, and communities within a defined budget. The [...]
Scaling traffic variables from sensors sample to the entire city at high spatiotemporal resolution with machine learning: applications to the Paris megacity
Published: 2024-04-10
Subjects: Transportation Engineering
Road transportation accounts for up to 35% of carbon dioxide and 49% of nitrogen oxides emissions in the Paris region. In an effort to mitigate those emissions, local authorities have implemented a climate plan that includes measures such as converting car lanes into cycle paths and enforcing strict low emission zones. Moreover, the COVID-19 crisis has had a notable impact on citizens' behavior [...]
Deep Deconvolution for Traffic Analysis with Distributed Acoustic Sensing Data
Published: 2021-09-23
Subjects: Artificial Intelligence and Robotics, Geophysics and Seismology, Transportation Engineering
Distributed Acoustic Sensing (DAS) is a novel vibration sensing technology that can be employed to detect vehicles and to analyse traffic flows using existing telecommunication cables. DAS therefore has great potential in future "smart city" developments, such as real-time traffic incident detection. Though previous studies have considered vehicle detection under relatively light traffic [...]
Transportation Network Vulnerability and Accessibility for Critical Amenities during Flooding: A Case Study for Iowa
Published: 2020-08-16
Subjects: Civil and Environmental Engineering, Civil Engineering, Engineering, Environmental Engineering, Hydraulic Engineering, Other Civil and Environmental Engineering, Risk Analysis, Transportation Engineering
Natural disasters, such as flooding, can cause severe social, environmental, and economic damage to a community. Transportation infrastructure plays an essential role in flood response and recovery efforts. However, flooding may disturb road functionality and generate direct and indirect adverse impacts, including the loss of access to essential services. This paper presents a comprehensive [...]
