| August Spotlight: Summer Travel |
|

Summer travel season continues to elevate the importance of customer experience in transportation. As more passengers fill airports, understanding traveler expectations and behaviors has become vital. ACRP Research Report 231: Evaluating the Traveler's Perspective to Improve the Airport Customer Experience guides airport operators in delivering seamless, customer-centered experiences across every journey phase—from trip planning to return. With new technologies and shifting traveler needs, this research emphasizes using customer insights to drive innovation, such as the outdoor seating area at San Francisco International Airport (pictured). A multimedia tool offers practical perspectives and real traveler stories to help agencies better meet demand. As summer crowds surge, improving airport experiences isn’t just ideal—it’s essential. For much more across all modes, take a look at the new National Academies Press Recreational Travel Collection.

Chicago is tackling drug use on transit with cross-agency support. Denver is reducing drug use on transit with smart design. L.A. and Philadelphia are combining strategy with compassion. TCRP Synthesis 179: The Impacts of and Response to Drug Use on Transit, released this week by TRB's Transit Cooperative Research Program, details how transit agencies are addressing the consumption and distribution of illegal drugs on their systems and the many ways they are trying to improve data collection and support services that can help make their systems safer and healthier for everyone.

On a sparkling morning last fall, an unusual-looking passenger ship departed from Tappström, Sweden, and silently soared above the waves toward central Stockholm, completing the 9.3-mile trip in 30 minutes. The voyage—which sped suburban commuters to the capital in half the time it would have taken them to drive—marked the debut of the world’s first all-electric hydrofoil ferry line. It also offered a glimpse of the potential for e-ferries to transform public transportation infrastructure by making commuting by water affordable, nonpolluting, and swifter than traveling by car. Read all about it in the latest issue of TRB's quarterly magazine TR News (Issue 354, Summer 2025).
