A new study sheds light on the importance of street design, especially as it relates to traffic and pedestrian safety.
In Nevada - from 2019 to 2022 - the number of traffic deaths increased 30%, according to the National Transportation Research Project.
Shima Hamidi, director of the Center for Climate-Smart Transportation and assistant professor of public health at Johns Hopkins University, helped lead the study.
She said switching lane widths between 11 to 12 feet down to 9 feet, can help reduce traffic collisions.
"But what we found in this study," said Hamidi, "a national study of more than 1,100 streets in the U.S. - is that when streets become wider, then it gives the drivers this false sense of safety that makes them drive faster."
Hamidi contended that speed is the main cause of most crashes, and when streets are more narrow, drivers tend to be more cautious.
According to the study, there are 1.5 times more crashes on roads when the lane width increases from nine to 12 feet.
The report includes policy recommendations, like prioritizing street design over driving speed and functionality.
Hamidi said another benefit to narrowing lane width relates to the environmental impact it can have on communities. She said less asphalt used for streets and roads equates to less heat.
"Really," said Hamidi, "the cause of urban heat islands - which is one of the most challenging climate change issues of our time - all of that comes with wider lanes."
Hamidi added that city and state transportation departments could pair lane-reduction projects with other initiatives, like adding bike lanes or larger sidewalks to make streets what she called "more livable."
For those worried about traffic congestion, Hamidi said narrower roads will likely slow down the speed of traffic, but that doesn't mean there will be more traffic.
"It will help many people to switch from driving to other modes of transportation," said Hamidi, "such as biking and walking, which could result in greenhouse gas emission reductions from transportation."

The number of registered electric vehicles in Indiana rose from 13,000 in 2023 to nearly 15,000 in 2024. However, plans to install more EV chargers in Indianapolis are on hold due to President Donald Trump's executive order to freeze federal spending linked to the 2024 Biden-Harris Administration Bipartisan Infrastructure Law.
Mo McReynolds, interim director of the Office of Sustainability for the City of Indianapolis, said the city applied for funding between 2021 and 2024 and was approved for millions last year and should the federal government authorize funding distribution within weeks or months, plans will designate local charging and fueling infrastructure sites to appear at popular neighborhood places.
"We were awarded $15 million, in that realm, to establish as many sites as we can afford within that budget," McReynolds explained. "We're still determining that amount within a partnership with Indianapolis public libraries, Indy park locations and culturally relevant sites for Black and brown communities."
Investments will make modern and sustainable infrastructure accessible to all drivers of electric, hydrogen, propane and natural gas vehicles. Indiana Vehicle Fuel Dashboard data shows Marion County has the highest number of state-registered vehicles under the four categories at slightly under 3,000. Union County has the lowest with four vehicles.
Pending funding disbursement, McReynolds pointed out the initial $15 million grant timeline is for five years. It is meant to coordinate with the National Electric Vehicle Infrastructure program for corridors and highways. Her office is establishing a grant agreement with the Federal Highway Authority for projects on a more local level.
"Ours are more focused on the community, so we hope to begin that process this year," McReynolds emphasized. "We may begin procurement with EV charging companies in 2026."
A significant amount of time will be taken to evaluate current and potential sites in Indianapolis. McReynolds indicated her office intends to do proper community engagement by speaking with residents to ensure EV chargers are welcome in their communities. Due to Trump's executive order to hold off on fund disbursement, Indianapolis Mayor Joe Hogsett is monitoring any further developments and is awaiting further guidance.

Massachusetts will benefit from more than $100 million in new federal funding for various transportation projects.
Neighborhoods divided by busy roadways in Somerville, Mattapan and Pittsfield will be reconnected with new street-level pathways while more than 400 new electric-vehicle charging ports will be installed statewide.
Quentin Palfrey, director of federal funds and infrastructure for the Massachusetts Executive Office for Administration and Finance, said funds will also improve more than 50 high-risk rail crossings.
"Some of these new resources are going to help us to expand rail and transit, move forward West-East rail and also improve the safety of our transit system," Palfrey outlined.
Palfrey noted the goal is to create a more accessible and climate-resilient transit system. The state has secured more than $9 billion in federal funds over the past two years, including nearly $2 billion to replace the Cape Cod Bridges.
The funding stems from the Bipartisan Infrastructure Law, the largest federal investment in public transportation in the nation's history. In addition to upgrading existing structures, projects are also improving access to natural resources.
Palfrey pointed out more than $17 million will support expansion of the Ashuwillticook Trail, creating a network of paths from Adams to Williamstown.
"It's a major priority across our transportation system," Palfrey emphasized. "This is going to be a really big step forward for Berkshire County's efforts in that regard."
Palfrey added state officials are building a transit network to serve everyone no matter how they travel, while helping to meet the state's ambitious climate goal of net-zero emissions by 2050.

A leading consumer publication says electric vehicles are gaining ground on gas-powered cars when it comes to feelings about reliability.
However, an EV enthusiast and Nebraska electrical engineering professor and said there's an information gap, while also highlighting improved technology.
The new reliability survey from Consumer Reports found that EV owners reported 42% more problems than gas-only cars.
That compares to nearly 80% from the previous survey, indicating a major improvement.
Retired University of Nebraska professor Don Cox said the batteries in most EVs are much better than they used to be, potentially easing concerns about them performing in colder climates.
"Batteries have improved a lot over the last 10, 15 years," said Cox. "A huge amount. They are continuing to improve."
However, he said EV batteries will always need a little time to warm up when it's cold, impacting their range in the winter.
Even though that perfection might never be achieved, Cox and other researchers say EVs are proving to be more efficient than gas models, overall.
He said he disagrees with how Consumer Reports puts together its evaluations, and added there isn't enough widely circulated ratings for buyers to lean on.
Dissecting issues such as reliability often coincides with measuring sales of electric vehicles. Cox was one of the first EV owners in Nebraska, which still lags other states for these purchases.
But with the help of federal investments, he said more chargers are being added, including near interstates to accommodate longer trips.
And the median range has increased from 80 miles in 2010 to roughly 250 miles today.
"I think that as people understand more about electric cars," said Cox, "that they're going to be more useful almost everywhere."
Nationally, researchers say issues still have to be sorted out in building up a strong charging network.
That includes drivers encountering broken charging equipment and the need for these sites to be maintained.
