AASHTO: Improving the Resilience of Our National Transportation System through Lifecycle Based Roadside Planning, Design, and Maintenance

May 19, 2021 @ 10:00 am - 12:00 pm CDT

Of all the land owned and maintained within the national highway transportation system, up to two-thirds is unpaved. Historically roadside design and maintenance has prioritized research focus on traffic safety, stormwater filtration and drainage, and visual quality. However over the past several decades there has been research to show the roadside’s potential as an environmental asset that if managed strategically, can help improve system resilience and overall sustainability. Some of the most compelling recent research has shown potential for significant return on investment from management strategies to support pollinators, sequester carbon, and make the transportation system more resilient to fire. The TRB standing committee on Roadside Maintenance Operations (AKR20) has been coordinating with the standing committee on Landscape and Environmental Design (AFB40) for the past twenty years on the development of National Guidelines for Vegetation Management (AASHTO, March 2011). This presentation will discuss the history of this research collaboration and the two committees’ current NCHRP research proposal to establish a facilitated ongoing national dialogue on best management practices for management of highway transportation roadside assets.
