A team of 2024 - 2025 University Design Competition awardees

Congratulate the winners of TRB’s Airport Cooperative Research Program University Design Competition for Addressing Airport Needs. This annual competition encourages students to design innovative and practical solutions to challenges at airports. Four first-place winners from Embry-Riddle Aeronautical University, University of Colorado, Boulder, Lawrence Technological University, and Purdue University were chosen across the technical challenge areas: Airport Environmental Interactions; Airport Safety, Operations, and Maintenance; Passenger Experience and Innovations in Airport Terminal Design; and Airport Management and Planning.

In Kansas City, MO, KC Streetcar announced a record-setting 838,000 passenger trips around the 2026 FIFA World Cup. With a population of about 2.2 million people in the metro area, how many people could the streetcar reasonably serve? The updated TCRP Research Report 262: Transit Capacity and Quality of Service Manual can help answer that question.
 
Many U.S. passenger rail services operate in corridors serving both freight and passenger rail where access is negotiated to balance both needs. New technology can automate train signals for efficiency, but doesn't change the number of people a station platform can hold or make it easier for riders to disembark. When calculating train timetables, tools allow you to do so for each individual train, but don’t account for human behavior, route and weather conditions, and rolling stock. Find methodologies to help establish operating margins and recovery factors despite unexpected slowdowns in TCRP Research Results Digest 122: Operating Margin and Recovery Factor Practices for Travel Time Estimation and Rail Scheduling.
 
Whether you have flat or flying junctions, use the TCQSM and accompanying research results digests when making capacity and service decisions.
