Dr. Mark Abkowitz: Transportation Risk Assessment, Safety and Security
Introduction to Transportation Risk Assessment
Overview of the Speaker and Their Work
- Mark Abitz introduces himself as a professor at Vanderbilt University, specializing in civil and environmental engineering.
- He emphasizes his interdisciplinary approach, collaborating with various departments including business and law schools to tackle modern problems.
Focus on Transportation Systems
- Abitz discusses his long-standing involvement in transportation risk assessment, particularly concerning safety and security within freight transportation systems.
- The use of spatial analysis is highlighted as a key technique for visualizing operational data to aid decision-making.
Spatial Analysis in Freight Transportation
Identifying High-Risk Areas
- The application of geographic information systems (GIS) technology is used to identify high accident locations on the rail network, marked in red for visibility.
- Hotspots indicate areas needing attention for accident mitigation strategies or potential rerouting of sensitive materials like chlorine or ammonia.
Advanced Mapping Techniques
- An automatic information system records vessel movements along a river, providing insights into travel speeds and patterns that affect efficiency and safety.
- This dynamic video representation aids planners and operators in strategizing improvements for future performance.
Climate Change Research Impacting Transportation
Simulating Hurricane Events
- Abitz's research includes simulating hurricane impacts on infrastructure adaptation within transportation systems.
- The simulation illustrates varying impacts across different land masses during a hurricane event, emphasizing the need for resilient infrastructure.
Utilizing Satellite Imagery
- Research extends beyond GIS tools to include satellite imagery analysis over time, comparing flooding and land use changes from 1990 to 2009.
- Temporal analysis reveals significant alterations in river contours and flood-prone areas, informing future planning regarding risk management.
