A National Cooperative Highway Research Program project will address the question “What can state DOTs to do reduce greenhouse gas emissions from the transportation sector?” The workshop is meant to inform that project, and state DOTs efforts in general, by bringing together a diverse group of traditional and non-traditional perspectives to discuss and provide recommendations around planning, system efficiency, vehicles, fuels, etc. The agenda will include some brief updates about current efforts to decarbonize transportation from three state DOTs followed by facilitated small group discussions and an engaging panel discussion/report-out.
The Role of State DOTs
1. What has been the role of state DOTs in reducing transportation sector GHGs in the past 10 years?
2. Where could/should be the role of state DOTs in the future?
3. Are there certain action that make most sense to happen at the state DOT level, versus other levels of government (e.g., city, county, regional, federal)?
4. Developments in CV/AV and shared use mobility could have profound effects on transportation GHG emissions. What can state DOTs do to help ensure these developments support climate change goals?
5. The three revolutions (autonomous, shared, and electric vehicles) will have profound effects on the transportation system and the role of state DOTs, and significant implications for reducing greenhouse gas emissions.
6. What steps can state DOTs take to ensure they are not only prepared for these revolutions and positioned to ensure they promote a low carbon transportation sector of the future?
8. How do state DOTs assess the GHG impacts of highway capacity expansion projects, including managed lanes, and how can we ensure these projects support GHG reduction goals? We still have a long way to go to understand GHG impacts of traditional highway projects, including managed lanes.E.g., how well do DOTs account for factors like speed changes, induced demand, and vehicle occupancy changes?
9. State DOTs often work with local partner agencies when highway system improvements are needed for new land development projects. How can DOTs better coordinate their transportation decisions with land use decisions to achieve GHG reductions?
