TRB Webinar: Experiences in the Use of Mini and Modular Roundabouts by Highway Agencies | June 25, 2026 11:00 AM - 12:30 PM U.S. Eastern | 1.50 | 0.00 | 1.50 | 0.00 | While full-sized roundabouts are a proven solution for addressing safety and mobility at intersections, their costs have risen relative to other intersection control types, prompting interest in lower-cost alternatives. TRB will host a webinar on Thursday, June 25, 2026 from 11:00 AM to 12:30 PM Eastern that will explore how highway agencies are planning, designing, and implementing mini and modular roundabouts as cost-effective intersection solutions. Presenters will highlight mini roundabout use on higher-speed rural roadways and near schools, where they can efficiently manage peak traffic flows and improve safety. Presenters will also examine the limited but growing use of modular roundabouts, including the contexts in which they have been deployed and the challenges affecting broader adoption. |

TRB Webinar: Are You Using Automated Traffic Signal Performance Measures Effectively? | June 30, 2026 12:00 PM - 01:30 PM U.S. Eastern | 1.50 | 0.00 | 0.00 | 0.00 | Automated traffic signal performance measures (ATSPMs) are a promising tool for improving operations at signalized intersections, yet their implementation and use vary widely among agencies. Understanding current practices and lessons learned can help agencies overcome barriers and expand the effective use of these tools. TRB will host a webinar on Tuesday, June 30, 2026 from 12:00 PM to 1:30 PM Eastern that will discuss the practices for traditional and crowd-sourced ATSPMs, present case examples from five state DOTs, and highlight recommendations for future research. It will explore different use cases, common challenges, and the factors that have contributed to successful ATSPM deployments. Attendees will gain insight into barriers that have limited broader adoption and practical strategies to address them, as well as a clearer understanding of how ATSPMs are being applied across the United States. |
