Building Information Modeling for Bridges and Structures: From Design to Construction Workshop
12/23/2022 7:00:49 PM
Building information modeling (BIM) has been used in the vertical construction industry since the 1970s. In the last decade, the worldwide transportation industry has been pushing for the implementation of BIM for bridges and infrastructures. This process revolutionizes the way projects are delivered and, to be successful, it requires the cooperation of all parties involved in the realization of the structure. TRB's Transportation Research Circular E-C282: Building Information Modeling for Bridges and St...
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...
A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology
4/14/2022 3:00:12 PM
Approximately 1,282 fatalities on U.S. interstate highways in 2020 were due to nighttime road departures. A new ultra-bright retroreflective lane marking tape can save lives as well as offer both a very short payback period and a very substantial benefit/cost ratio over its useful lifetime. The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 228: A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology details a new product whic...

Methods for State DOTs to Reduce Greenhouse Gas Emissions from the Transportation Sector
3/14/2022 12:00:00 PM
Many technical and institutional issues related to estimating and reducing greenhouse gas emissions (GHGs) lie across a wide spectrum of the activities undertaken by state departments of transportation (DOTs). The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 308: Methods for State DOTs to Reduce Greenhouse Gas Emissions from the Transportation Sector documents the research effort for an NCHRP project that focused on developing a guide for state DOTs on reducing GHG emission...
September-October 2021: State of Emergency: What Transportation Learned From 9/11
1/28/2022 1:00:15 PM
Since the terrorist attacks of September 11, 2001 (9/11), transportation has broadened its role to include response and operations—from traffic incident management as a multiagency function to aviation security. But in the 20 years since 9/11, natural disasters, technology changes, and pandemics have presented new challenges. In the September–October 2021 issue of TR News, authors address these challenges, as well as how transportation agencies can incorporate resilience to respond quickly and effective...
