Development of a Small Aircraft Runway Length Analysis Tool
9/16/2022 6:01:37 PM
An important operational characteristic of an airport is the length of its longest runway. The longest runway determines the types of aircraft that can use the airport and dictates the operational limitations at the airport. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 54: Development of a Small Aircraft Runway Length Analysis Tool provides a user-friendly computer tool to help airport planners and designers estimate runway length requirements for a variety of aircraft and design...

Investing in Transportation Resilience: A Framework for Informed Choices
8/5/2021 3:02:47 PM
Significant progress has been made over the last decade in integrating resilience criteria into transportation decision-making. A compelling case remains for investing in making transportation projects more resilient in the face of increasing and intensifying storms, floods, droughts, and other natural hazards that are combining with sea-level rise, new temperature and precipitation norms, and other effects from climate change. TRB’s Special Report 340: Investing in Transportation Resilience: A Framework...
