Georgia DOT Context Classification of State Routes
Georgia
Georgia DOT developed a context classification framework for state routes. Using measures such as intersection, population, and employment density, routes are categorized into seven types—from rural and rural town to urban core. This approach supports context-sensitive design and enhances safety.
This project develops an integrated, network-level pavement friction management framework for Illinois. It transforms friction, traffic, and pavement characteristics into crash-risk measures and integrates them with life-cycle cost analysis to support proactive pavement management decisions.
Reliable crash prediction depends on quality data. By combining Idaho and Utah roadway inventory and crash data, ITD improved crash prediction models. This enables Idaho to better identify safety projects and allocate funding using the combined AASHTOWare Safety partner data.
Traffic safety projects can produce varying impacts on safety performance. While some projects substantially reduce crashes, others may yield limited or unexpected measurable effects. Establishing a robust framework for tracking crash histories associated with safety projects is therefore essential for the Iowa DOT and other state DOTs to assess project effectiveness, efficiency, return on investment, and broader safety performance implications.
Leveraging Delivery Mechanisms – Road Reconfigurations Through Resurfacings
Georgia
A common DOT challenge is need that exceeds available funding. GDOT’s Safety Program works with the Resurfacing Program and leverages On-Call Requests (OCR) to deliver road reconfigurations – reducing costs and accelerating timelines on improvements for vulnerable road users and speed management.
HDR helped MnDOT to study the safety performance of roundabouts in Minnesota. A unique aspect of this study was the evaluation of various roundabout features (such as number of legs, circulating lanes, radius, curvature, signing, etc.). The poster highlights the findings from this study.
Lighting Design Guidelines for Pedestrian Crosswalks
Massachusetts
MassDOT is developing a a lighting design guide for crosswalks with the goal of improving the safety of nighttime crossings. The guide includes tools to help designers prioritize crosswalk lighting improvements based on crash history, risk, and pedestrian demand, supporting safer crossings statewide.
Speed Safety Cameras in School Zones: North Carolina DOT Support for Local Readiness
North Carolina
The poster will show how North Carolina Department of Transportation supported work to translate a new state speed camera law into practical local readiness through feedback, peer exchange, and State agency participation, providing a repeatable approach for the implementation of other emerging safety technologies.
