Wisconsin's largest city has seen recent debate over highway expansion plans amid environmental concerns, and a new study suggested for similar projects, some effects could be limited if narrower traffic lanes are prioritized.

The expansion plan in Milwaukee involves a stretch of Interstate 94. Research from the Johns Hopkins Bloomberg School of Public Health was more focused on urban roadways with speed limits of around 35 miles an hour.

Shima Hamidi, director of the Center for Climate-Smart Transportation and assistant professor of public health at Johns Hopkins University who helped lead the study, said switching from lane widths between 11 and 12 feet, long the norm, down to 9 feet helps reduce traffic collisions. She pointed out it also leaves more room for options not involving vehicles.

"It will help many people to switch from driving to other modes of transportation, such as biking and walking," Hamidi explained. "Which could result in greenhouse gas emission reductions from transportation."

The study contended with narrower lanes, people will not feel compelled to drive as fast and will be more alert. Hamidi acknowledged while the approach might slow traffic, past research shows minimal effects, which means the changes would not cancel out environmental benefits. Other studies have shown expanding the number of lanes, in general, does not reduce congestion.

Hamidi also noted transportation planners and engineers have expressed liability concerns, but she emphasized her team's study is one of the first to give cities and states firm data, on the traffic safety side, showing skinnier lanes are more effective.

"We are getting more and more interest from transportation planners, mostly at the local level," Hamidi observed. "Cities are eager and interested to really see how this could be implemented."

Hamidi added the next steps involve more research to quantify some of the other impacts, including air pollution. The study issued this month analyzed nearly 1,200 streets in seven cities around the
U.S. The findings come amid a gradual increase in pedestrian fatalities over the past decade.

President Donald Trump's budget bill took another step forward Tuesday by passing in the U.S. Senate.

The bill would end some tax credits one Kansas manufacturer said are vital to American competitiveness abroad.

Kurt Neutgens, cofounder and president of Kansas City-based Orange EV, which manufactures electric yard hostlers, chargers and battery storage systems, explained his industrial customers use a $40,000 tax credit to help purchase his all-electric yard hostlers for loading and unloading cargo.

Senate Republicans voted to cut the tax credit by September. Neutgens pointed out EV manufacturers, and renewable energy companies in general, frequently compete with Chinese manufacturers, which are subsidized by the government.

"If we don't support clean energy, from materials to manufacturing to assembly to even clean energy products all the way up to vehicles, in this bill then we are really handing dominance to China for all of that," Neutgens asserted.

Policies like the EV tax credits from President Joe Biden's Inflation Reduction Act have been in the Trump administration's crosshairs. Republican lawmakers have argued market competition should be the driving force on which vehicles -- electric or gas -- people drive.

Neutgens, who employs more than 300 people, said tax credits help the electric vehicle manufacturers increase their volume, which will allow them to compete with China.

"We need these incentives to be able to get ourselves to a level where we have enough volume so that we can compete," Neutgens emphasized. "Even though they're getting government subsidies."

A study by Princeton University found if electric vehicle tax credits are cut and clean air regulations for vehicles are curtailed, EV sales could drop up to 40% by 2030, compared to what they'd be if the Biden-era policies continued.

The U.S. Department of Transportation has frozen millions in grant dollars awarded by the Biden administration, leaving those counting on them in limbo.

Powell County, Montana was set to receive more than $6.3 million for its Parks to Passes project, a collaboration with neighboring groups and governments to close gaps in a pedestrian and biking corridor spanning roughly 230 miles between Butte and the Idaho border. The trail is part of the larger Great American Rail-Trail route.

Kevin Mills, vice president of policy for the Rails to Trails Conservancy, said the eventual coast-to-coast trail will stretch 3,700 miles from Washington, D.C., to Washington state.

"It's really stalling an important connection in that nationwide trail," Mills pointed out. "That puts at risk Montana's potential to tap into what we've calculated to be $16 million in new economic development."

The grant was part of President Joe Biden's Rebuilding American Infrastructure with Sustainability and Equity program. U.S. Transportation Secretary Sean Duffy said the Biden administration delayed construction with, quote, "leftist social requirements" including the consideration of a project's climate change and social justice impacts.

In addition to economic and climate benefits, effective trail corridors improve safety. Mills noted 9,000 pedestrians and cyclists die on roads each year in the U.S. and 130,000 more are injured.

"This is a problem that's really grown over the last decade because we don't really provide safe places to walk and bike," Mills explained. "These federal grants that are on hold are sorely needed to make the situation better."

In Montana, he added, about $200 million in grants have been frozen, including $10 million for trail projects.

New data show Arizona's two largest airports have fared well for on-time departures and arrivals but the same cannot be said about U.S. airlines in general.

Air travelers filed about 67,000 complaints last year, up 9% from 2023, according to a new report from the Public Interest Research Group Education Fund. The top grievances were cancellations and delays, not receiving refunds and luggage being lost or damaged.

Teresa Murray, consumer watchdog director for the group's Arizona education fund, said the number of travelers was expected to increase by about 7% this year but economic uncertainty and concerns from international travelers has curbed it. She noted Delta, Southwest and United have all indicated they will cut their number of flights in the months ahead.

"Then you throw in the safety issue," Murray added. "We don't have any way of knowing -- and I don't think the airlines really know for sure -- what to expect in the months ahead, although it is certainly expected that maybe we won't see a 7% increase in passengers this year."

Murray pointed out travelers have more rights this year than they did a year ago. For instance, complaints about refunds and delays prompted action from Congress on an FAA reauthorization bill, which mandates airlines to issue fast, no-hassle refunds if a flight is canceled for any reason.

Murray noted overall, cancellations and delays across the nation increased last year. Just this week, Newark Airport saw many delays and cancellations after the FAA issued a ground stop following an outage at one of its air traffic control facilities. Murray argued flyers need to be in the know and on alert about where they are flying through.

"Pay attention to the news," Murray urged. "Because there are going to be other hot spots where, because of the air traffic control shortages and because of equipment, there may be some airports that are just a little bit more headache-inducing than what we've seen."

Murray realizes some are on edge about the current state of the airline industry but emphasized being courteous and respectful to fellow passengers and airline representatives goes a long way.
