Airports, while physically located within individual states, operate as instruments of commerce subject to federal jurisdiction as part of the national transportation system. This duality requires airports to navigate multiple layers of laws and regulations. It is particularly significant in the context of cannabis, where some states have legalized the substance for certain uses while federal law continues to prohibit it. TRB will host a webinar on Tuesday, April 21, 2026 from 2:00 PM to 3:30 PM Eastern that will provide insight into the legal impacts to airports from the legalization of cannabis by identifying key issues and corresponding legal guidance.
This webinar is based on ACRP Legal Research Digest 49: Legal Impacts to Airports from State Legalization of Cannabis.
This webinar is sponsored by TRB’s Airport Cooperative Research Program.
There is no fee to attend this webinar. Registration is required.
A recording will be sent to all registrants after the webinar.

Ensuring the safety and security of customers is a core responsibility of public transit agencies, and perceptions of personal safety strongly influence travel behavior. Concerns about assaults and fear while traveling or waiting for service can deter transit use, while research suggests that improving feelings of security could increase ridership. TRB will host a webinar on Tuesday, April 28, 2026 from 1:00 PM to 2:00 PM Eastern that will highlight practical strategies and real-world experiences from transit agency leaders who have taken action to strengthen security and reduce the likelihood of assaults. The session will feature findings and tools from two TCRP studies, including a transit security guide, a mitigation interactive matrix, and a social media toolkit designed to support agencies in their efforts. Presenters will share their research and perspectives and discuss lessons learned from implementing measures to improve security for passengers and transit workers.
This webinar is based on TCRP Research Report 258: Mitigation Strategies for Deterring Transit Assaults and TCRP Synthesis 184: Improving Transit Customer Perception of Personal Security.

State transportation agencies are required to collect and analyze safety-related and other data under federal law, and that information is frequently used in public outreach, safety studies, litigation, and responses to public records requests. The collection, retention, and release of this data are subject to recordkeeping requirements, privacy considerations, 23 USC 407, and other state and federal laws. TRB will host a webinar on Thursday, April 30, 2026 from 11:00 AM to 12:00 PM Eastern that will examine the legal implications associated with data collected in the normal course of agency business and explore how those requirements affect day-to-day technical and programmatic activities. Presenters will review key legal concepts, outline regulatory considerations, and offer practical strategies for navigating data collection, retention, and disclosure requirements.
This webinar is sponsored by TRB’s Standing Technical Committee on Safety, Risk Management and Tort Liability.
The registration fee is $60. Purchase a webinar package for discounted pricing.
