High-speed Rail is Happening and TRB Can Help

Ground was broken this past week on a high-speed train line that will transport passengers as soon as 2028 in two hours between Los Angeles and Las Vegas. Officials called it "the beginning of the high-speed rail era in the United States of America."

TRB has many valuable resources to help the rail industry make that happen. These include publications and opportunities with our Standing Technical Committee on Passenger Rail Transportation.


On-demand aviation_ti4.JPG

On-Demand Services for Mobility, Logistics, Emergency Response, and Humanitarian Use Cases (Transportation Insights 4). Aviation is undergoing a transformation. Advancements in technology are enabling innovations in regional and on-demand aviation. Many challenges are currently being addressed, including community acceptance, safety, equity, issues around planning and implementation, airspace, and operations.

New TRR Article Details How Rail Technologies are Adapting 

As commuter railroads consider new propulsion technologies to reduce the carbon footprint of their operations, early 20th-century experiences with electrification offer useful perspectives for tomorrow's technology choices. An article in TRB's Transportation Research Record journal finds that choices by railroads of their current and voltage, as they consider the technologies available, appear to correspond closely today to the ways they corresponded in the past.

Challenge the Students in Your Life to Improve TCDs

Encourage individuals or a team of students to participate in the Traffic Control Device Student Challenge. Students this year will focus on innovative TCDs to improve roadway worker safety. From 2017 to 2021, data revealed an annual average of 108,000 work zone crashes nationwide. Encourage the students you know to submit their entries by October 1.

TRB In the News

PFAS Structure_ACRP RR 255.JPG

The U.S. Environmental Protection Agency recently announced new requirements to limit harmful PFAS chemical compounds in drinking water. Airports are among potential PFAS sources, and Aviation Pros reports that they are prepared because of a TRB Airport Cooperative Research Program report that provides "a practical, data-driven approach to build lines of evidence as to whether activities at the airport, or from other sources, may have contributed to PFAS found on or near the airport property."

TRB's "future of the interstate" concensus study was mentioned in three articles:

  • The Trucker cites the 2019 report in an article about the Baltimore bridge collapse, noting that U.S. interstates have "a persistent and growing backlog of physical and operational deficiencies as a result of age, heavy use and deferred reinvestment, and [are] in need of major reconstruction and modernization."
  • Medium reports that regional air mobility depends on better roads to airports and "an increase in combined state and federal expenditures to sustain our interstates ... from $20-$25 billion to $40-$70 billion annually."
  • For Construction Pros added, "That sounds like a huge leap, except that the Infrastructure and Jobs Act signed into law on November 15, 2021, committed $350 billion in highway and bridge funds over a five year span, ending in 2026."

The California grid will require major upgrade to meet EV demands, costing between $6 billion and $20 billion, according to a new study in the Proceedings of the National Academy of Sciences reported on in The Hill.
