TRB Weekly covers the latest in transportation research.

Pollinators and Vegetation are Crucial Cogs in the Roadside Toolkit

Transportation agencies can make a difference for imperiled pollinators by managing existing roadside vegetation and designing new revegetation plantings with habitat needs in mind. This can generate public support for agencies and help to mitigate the negative ecological effects of roads.

Pollinator Habitat Conservation Along Roadways, Volume 1: Alaska (NCHRP Web-Only Document 362), from TRB's National Cooperative Highway Research Program, is the first in a 16-volume series. Each volume focuses on a specific region of the United States and is intended to provide relevant guidance to rights-of-way owners and operators for roadside vegetation management practices that support pollinators, as well as strategies that are compliant with the federal Endangered Species Act.

This volume and the next three (on California, Florida, and the Great Basin) have just been released, with four more volumes to become publicly available each of the next three weeks.

Find additional resources for improving the relationship between transportation and wildlife in our updated blog post. 

New TRB Publications

Autonomous Safety 3.JPG

Toward a National Regulatory Framework for Automated Vehicles: Challenges and Opportunities (TR Circular E-C284). The deployment of automated vehicles, shared mobility services, and other transformational transportation technologies has the potential to dramatically increase safety, reduce congestion, improve access, enhance sustainability, and spur economic development. However, success in meeting these goals is not assured and there are significant risks that these deployments could cause unintended consequences.
