STUDIES & RESEARCH ON EXTREME WEATHER & THE TRANSPORTATION SYSTEM
NCHRP 750, VOL. 2
![Page 5: Extreme Weather Research and Tools Update Date: May 29, 2014 Committee: Standing Committee on Highways Presenters: Michael D. Meyer, Parsons Brinckerhoff](https://reader035.vdocument.in/reader035/viewer/2022070413/5697bfd61a28abf838cae0a8/html5/thumbnails/5.jpg)
KEY QUESTIONS
• How Could Changes in Temperature Affect Road Assets?
• How Could Changes in Precipitation Affect Road Assets?
• How Could Sea-Level Rise Affect Road Assets?
• How Could Greater Hurricane Intensity Affect Road Assets?
• How Could Stressors Affect Ecological Systems?
• What Are the Types of Adaptation Strategies that Can Be Considered by Transportation Agencies?
