Dozens of cyclists and pedestrians are killed each year in Philly − an injury epidemiologist explains how to better protect bike lanes, slow drivers down and reduce collisions
Compared with other big cities, Philadelphia’s death rate for both pedestrians and cyclists is higher than New York and Chicago but lower than Los Angeles and Houston.
Across the U.S., more pedestrians and bicyclists are killed or seriously injured today than any time over the past 40 years. Over 7,500 pedestrians and over 1,100 bicyclists died in traffic collisions in 2022, the most recent year with available data, according to the National Highway Traffic Safety Administration.
As an injury epidemiologist in Philadelphia who studies pedestrian and bicyclist injuries in the U.S. and Latin America, I want to share several evidence-based ways that Philadelphia can make walking, biking and getting around the city safer for everyone.
Protect bike lanes
Protected bike lanes have physical barriers that prevent drivers from entering the bike lane to park or pass other drivers.
They are particularly useful on high-volume cycling corridors and offer cyclists much more protection than lanes that are merely painted but have no physical barriers or lanes with flexible posts that can be driven over.
Flexible posts, for example, were unable to block the collision that killed Barbara Friedes, chief pediatric resident at Children’s Hospital of Philadelphia, in Center City in July 2024 when a drunk driver sped through the bike lane where Friedes was bicycling.
In October 2024, the city announced it will install concrete barriers to protect the bike lanes on Spruce and Pine streets in Center City, including where Friedes was killed. That same month, the City Council unanimously passed a “Get Out the Bike Lane” bill that increases the fines for drivers who stop or park in a bike lane.

Slow drivers down
Traffic-calming measures are engineering and road design strategies that slow vehicles down, make pedestrians more visible to motorists and provide safer crossing areas.
Philadelphia can adopt more policies that promote walking or biking over driving. These include open streets or ciclovías, where streets are closed down to motor vehicle traffic and opened to cyclists and pedestrians. Philadelphia occasionally does this on stretches of 18th Street and Walnut Street in Center City.
This may be a challenge, considering the recent experience of New York City, which spent decades preparing for congestion pricing only to have it blocked by the governor, though it seems it now has a chance of being implemented. How much success New York has with congestion pricing will likely determine the feasibility in Philadelphia and other U.S. cities.

Considering the increase in road traffic deaths in Philly since the start of the COVID-19 pandemic, substantial efforts are needed to reach the city’s Vision Zero goal of reducing road traffic deaths to zero by 2030.
In my view, this includes better data on transportation use and which interventions and policies are working and which are not.

Road safety surveillance could be improved in Philadelphia and across Pennsylvania by linking crash records to other data, such as hospital and clinical data of crash victims, as well as insurance costs to better understand the burden of road traffic injuries on the city and the state.
Data is also key to ensuring public policies are implemented equitably. The Vision Zero plan includes a focus on lower-income neighborhoods and those with higher proportions of racial and ethnic minorities. Those areas have three times as many serious injuries and deaths as other neighborhoods, and road traffic injury and deaths rates are 30% higher among people of color compared with white residents.

Currently, getting a yearly COVID-19 vaccine is recommended for everyone ages 6 months and older, regardless of their health risk.
In the video announcing the plan to remove the vaccine from the CDC’s recommended immunization schedule for healthy children and healthy pregnant women, Kennedy spoke alongside National Institutes of Health Director Jay Bhattacharya and FDA Commissioner Marty Makary. The trio cited a lack of evidence to support vaccinating healthy children. They did not explain the reason for the change to the vaccine schedule for pregnant people, who have previously been considered at high-risk for severe COVID-19.
Similarly, in the FDA announcement made a week prior, Makary and the agency’s head of vaccines, Vinay Prasad, said that public health trends now support limiting vaccines to people at high risk of serious illness instead of a universal COVID-19 vaccination strategy.
Was this a controversial decision or a clear consensus?
Many public health experts and professional health care associations have raised concerns about Kennedy’s latest announcement, saying it contradicts studies showing that COVID-19 vaccination benefits pregnant people and children. The American College of Obstetrics and Gynecology, considered the premier professional organization for that medical specialty, reinforced the importance of COVID-19 vaccination during pregnancy, especially to protect infants after birth. Likewise, the American Academy of Pediatrics pointed to the data on hospitalizations of children with COVID-19 during the 2024-to-2025 respiratory virus season as evidence for the importance of vaccination.
Kennedy’s announcement on children and pregnant women comes roughly a month ahead of a planned meeting of the Advisory Committee on Immunization Practices, a panel of vaccine experts that offers guidance to the CDC on vaccine policy. The meeting was set to review guidance for the 2025-to-2026 COVID-19 vaccines. It’s not typical for the CDC to alter its recommendations without input from the committee.
Robert F. Kennedy Jr. has removed COVID-19 vaccines from the vaccine schedule for healthy children and pregnant people.
FDA officials Makary and Prasad also strayed from past established vaccine regulatory processes in announcing the FDA’s new stance on recommendations for healthy people under age 65. Usually, the FDA broadly approves a vaccine based on whether it is safe and effective, and decisions on who should be eligible to receive it are left to the CDC, which bases its decision on the advisory committee’s research-based guidance.
The advisory committee was expected to recommend a risk-based approach for the COVID-19 vaccine, but it was also expected to recommend allowing low-risk people to get annual COVID-19 vaccines if they want to. The CDC’s and FDA’s new policies on the vaccine will likely make it difficult for healthy people to get the vaccine.
Will low-risk people be able to get a COVID-19 shot?
Not automatically. Kennedy’s announcement does not broadly address healthy adults, but under the new FDA framework, healthy adults who wish to receive the fall COVID-19 vaccine will likely face obstacles. Health care providers can administer vaccines “off-label”, but insurance coverage is widely based on FDA recommendations. The new, narrower FDA approval will likely reduce both access to COVID-19 vaccines for the general public and insurance coverage for COVID-19 vaccines.
Under the Affordable Care Act, Medicare, Medicaid and private insurance providers are required to fully cover the cost of any vaccine endorsed by the CDC. Kennedy’s announcement will likely limit insurance coverage for COVID-19 vaccination.
Overall, the move to focus on individual risks and benefits may overlook broader public health benefits. Communities with higher vaccination rates have fewer opportunities to spread the virus.

The once red-hot U.S. residential solar market is showing signs of cooling off—but don’t count it out just yet. A combination of rising interest rates, regulatory changes, and supply chain challenges have led to a notable dip in installations across the country. But while the short-term trend suggests a slowdown, industry experts remain optimistic about the long-term potential of rooftop solar.
📉 The Numbers Don’t Lie: Installations Are Down
According to the Solar Energy Industries Association (SEIA) and Wood Mackenzie, residential solar installations dropped by 13% year-over-year in Q1 2025, with 1,106 megawatts (MW) installed nationwide. That’s also a 4% decline from the previous quarter. This marks a continuation of the trend that began in 2024, which saw the residential sector contract in 22 states—including a five-year low in California [^1].
Analysts at BloombergNEF predict that total U.S. solar capacity will fall by 7% between 2025 and 2027, with a projected 1% annual decline through 2035 under current policy scenarios [^2].
🧾 What’s Behind the Drop?
1. Higher Interest Rates
The Federal Reserve’s continued efforts to tame inflation have made financing solar systems more expensive for homeowners. The result? Fewer consumers are willing to commit to the upfront investment, even with long-term savings in play [^3].
2. Policy Shifts in Key States
California, long considered the leader in solar adoption, rolled back its Net Energy Metering (NEM) 2.0 program in favor of NEM 3.0, which significantly reduces the value of solar exports back to the grid. Installations in the state fell sharply as a result [^1].
On the federal side, proposed cuts to the 30% Investment Tax Credit (ITC)—a major driver of residential adoption—have caused uncertainty in the market. According to Reuters, solar stocks plummeted following changes in a Senate tax bill that threatened to shrink or eliminate these credits [^4].

3. Tariffs and Supply Constraints
Tariffs on Chinese and other foreign-made solar panels have led to price increases and reduced availability. Simultaneously, battery storage components are experiencing shortages, further delaying installations and complicating project timelines [^5].
🌤 The Long-Term Picture: A Resilient Future
Despite the headwinds, many in the industry see this as a short-term correction rather than a lasting decline. SEIA projects a return to 9% annual residential growth from 2025 to 2030, particularly if financing conditions improve and federal incentives remain intact [^1].
Additionally, solar panel prices remain historically low, hovering around $2.50–$2.60 per watt installed. That affordability, coupled with increasing demand for home electrification and EV charging solutions, makes rooftop solar an attractive long-term investment [^1].
In a recent industry survey, 78% of solar installers said they expect to sell as much or more in 2025 than they did in 2024 [^3]. And while the market is down in states like California, others—including Texas, Florida, and Arizona—are continuing to grow.
✅ Final Takeaway
Yes, residential solar is currently in a downturn. But it’s more of a recalibration than a collapse. Regulatory turbulence and financial pressures are squeezing the market, but the fundamentals—affordability, environmental benefits, and technological advancement—remain strong.
The future of residential solar will depend heavily on stable policy support, affordable financing, and continued innovation. If those stars align, the industry could see another boom in the latter half of the decade.
