The rise in drug use on transit systems has become one of the most pressing and complex challenges for U.S. public transportation agencies. TRB will host a webinar on Tuesday, October 14, 2025 from 1:00 PM to 2:00 PM Eastern that will highlight a first-of-its-kind report documenting how transit agencies in five cities—Portland, Denver, Los Angeles, Chicago, and Philadelphia—are responding to this issue. Presenters will share program and policy responses that address the impacts of illegal drug use on customer and staff safety and security, drawing from a literature review, in-person agency visits, staff interviews, and ride-alongs with outreach workers and law enforcement. Presenters will also discuss key challenges, areas of opportunity, and knowledge gaps in agency responses.

Well-designed bus operator workstations and barriers can decrease driver risks of low back pain and slowed response time. Improving the health and safety of bus operators’ physical environment makes the job more appealing and drivers more productive. TRB will host a webinar on Wednesday, October 22, 2025 from 11:00 AM to 12:00 PM Eastern that will discuss how to mitigate the health and safety risks that are present for bus drivers. Presenters will share strategies for addressing these risks and highlight effective approaches to improve the design and management of bus operator workstations.
This webinar is based on TCRP Research Report 247: Assessing Lifecycle and Human Costs of Bus Operator Workstation Design and Components and TCRP Research Report 249: Bus Operator Barrier Design: Guidelines and Considerations.

Transportation practitioners and decision makers alike can use TRB’s planning “snapshots” to develop, implement, and advance programs for Complete Streets, data sharing, freight delivery, and economic analysis. TRB will host a webinar on Friday, October 24, 2025 from 1:00 PM to 2:30 PM Eastern that will go through the process of creating concise summaries of current practices across these four topics by conducting and synthesizing practitioner surveys. Presenters will share findings from the snapshots, explain how the maturity-level spectrum can help agencies at different stages of implementation, and describe the repeatable process and tools created for use in future planning topics.
This webinar is based on NCHRP Research Report 1158: Developing Snapshots for Transportation Planning. Find the snapshots in NCHRP Web-Only Document 431: Snapshots of Planning Practices.

When risk management is proactively integrated into organizational decision-making, with risks clearly officially documented and considered, it leads to better management of resources and a culture of preparedness. TRB will host a webinar on Monday, October 27, 2025 from 1:00 PM to 2:00 PM Eastern that will focus on three levels of risk management: enterprise, program, and project. Presenters will share key needs, challenges, and knowledge gaps associated with integrating risk management, along with evidence-based strategies to sustain these practices within transportation agencies. Presenters will also introduce a website and digital content that provide guidance, examples, and tools to support transportation stakeholders in building and maintaining effective risk management frameworks.

The latest National Highway Traffic Safety Administration (NHTSA) data indicates that fatality and crash rates among teen drivers have been increasing over the past few years. TRB will host a webinar on Tuesday, October 28, 2025 from 2:00 PM to 3:00 PM Eastern that will discuss the results from two BTSCRP reports that used naturalistic driving data to gain a broader understanding of the risks facing teen drivers. Presenters will share evidence on how the amount of time spent with supervised experience in different roadway environments can improve safety outcomes once teens begin driving independently. Presenters will also discuss how distraction, specifically “eyes off the road,” changes with driving experience and why attention to the forward roadway is especially critical for teen learners. Newly-published findings compare risky driving and crash rates with for teens with distraction factors like Attention-Deficit/Hyperactivity Disorder.
This webinar is based on BTSCRP Research Report 13: Outcomes of Variability in Teen Driving Experience and Exposure: Evidence from the Naturalistic Driving Study and BTSCRP Research Report 15: Teen Driving Performance Associated with Distraction, ADHD, and Other Risk Factors.
