This webinar discusses a framework developed to identify gaps in transportation infrastructure needs data. Though 311 complaints are a key mechanism to identify areas in need, researchers argue that the types and rates of complaints vary by location data. Therefore, some places may end up with worse infrastructure simply because not enough complaints are generated there. The gaps framework is intended to help public-sector engineers and planners.
This webinar shares research findings on the results, best practices, and lessons learned from implementing diverging diamond interchanges (DDIs) and continuous flow intersections (CFIs) in Utah. It also covers establishing performance metrics and evaluation criteria to assess their success and effectiveness in support of planning, design, and implementation.
This webinar explored research findings on innovative approaches to managing highway infrastructure. Participants learned about a cost-efficient method for assessing culvert conditions and prioritizing maintenance tasks when highway data is limited. The session also examined the role of condition prediction models in optimizing maintenance budgets for underrepresented assets such as culverts. Further discussion addressed the efficacy of federated learning as a means of data sharing among state departments of transportation, enabling improved prediction accuracy while safeguarding data privacy.
Research at North Dakota State University shows that strategic deployment of advance air mobility, an emerging transportation system that uses highly automated, electric vertical takeoff and landing (eVTOL) aircraft, could reduce wear and tear on roads and bridges, reduce congestion, improve safety, and improve delivery reliability for high-value and time-critical goods
