Top officials from 14 state DOTs gathered in St. Paul, Minnesota, earlier this month for SSTI’s annual meeting, where they shared innovative ideas through roundtable discussions, tours, and informal networking. These connections help officials bring solutions back to their home states.

Moving from LOS to VMT is more complicated than it might seem
Traffic engineers across the U.S. are accustomed to measuring road performance in terms of “level of service,” or LOS. Recognizing its unintended consequences, many transportation professionals and advocates have urged the industry to replace it with something better. However, LOS has become so ingrained in many processes that there is probably no single alternative to its use.
Climate change presents an opportunity for bolder transportation policies
Individuals concerned about climate change often support sustainable transportation policies, such as reducing car use or adopting new mobility solutions. Studies from Norway highlight how varying attitudes toward these types of policies can influence their effectiveness. While some groups back most transportation initiatives—whether they involve incentives or regulations—others resist any policies they perceive as restrictive. Gaining insight into these diverse attitudes, especially among those neutral toward different strategies, can help shape effective policy.
States could fill policy vacuum in wake of recent Supreme Court ruling
Earlier this month, the U.S. Supreme Court issued a ruling expected to have sweeping impact across federal agencies, including the Department of Transportation. The decision, in a case called Loper Bright Enterprises v. Raimondo, gives judges more say in whether agencies are meeting the letter of the law. Under the previous “Chevron doctrine,” judges deferred to the expertise of federal rule makers as they interpreted laws to create rules and regulations. Now, judges will have more authority to interpret whether the rules federal agencies create match the law. That could provide a window of opportunity for those seeking to challenge a wide range of rules across the federal government, including transportation rules like a recent EPA rule that would force a faster transition to electric vehicle production.
Smaller infrastructure investments help pave the way to safer communities
Road safety is an urgent issue at all levels of government, especially for people walking and biking. Cyclist and pedestrian deaths have increased by. This infrastructure week, we are encouraging more states, cities, and other local governments to help reverse this trend by prioritizing critical safety investments on streets and highways across the country.
States must step up efforts to reduce harmful carbon emissions
As of last September, 16 states and Puerto Rico approved legislation requiring reductions in greenhouse emissions. The White House also set ambitious goals of cutting emissions by at least 50% below 2005 levels in 2030. They aim to achieve a net-zero economy by 2050. Contributing to 29% of all greenhouse gas emissions in the U.S., the transportation sector is now the top producer and accounts for a growing portion each year. More than half of these emissions (57%) come from personal vehicles such as cars, SUVs, and light-duty trucks. Progress in cutting those emissions has been slow, let alone efforts to measure and track them.
People on bikes are vulnerable and don’t need to be reminded
Late last month, the Texas DOT posted a message on X (formerly Twitter) urging cyclists to behave better. But this message garnered at least 250 frustrated responses. The echo chamber of X obviously is not a representative sample, but the backlash reflects real challenges that cyclists face every day. Unfortunately, people who bike—along with those who walk, take transit, or face other mobility issues—experience a world where most drivers do not follow the rules, which often puts them at a dangerous disadvantage.
Narrow lanes are safer, but they can be extremely difficult to build
A study released by Johns Hopkins last November gained widespread attention for demonstrating that 9-foot lanes are often safer than wider lanes. The researchers note, however, that most state DOTs set minimum lane widths between 10 and 12 feet and require design exceptions for anything narrower. Even in Vermont, where 9-foot lanes are allowed, the researchers found they have not been implemented. Therefore, paving the way to narrow lanes means understanding all the factors that make them challenging in the first place.
To effectively transition to zero-emission vehicles, many barriers need to be addressed
Electric vehicles (EVs) will be critical for meeting ambitious climate goals at the national, state, and local levels, but their rapid adoption continues to face challenges. This wrap-up touches on the latest barriers that are essential to overcome.
Everyone deserves to cross the street safely, including wildlife
Safety is a top priority for every state DOT, and in many parts of the country that effort extends to wildlife, as many species are changing their migration patterns to adapt to climate change.
