Growing up in a suburban town, I serpentined through my neighborhood streets every day after school. I also studied abroad in Copenhagen, Denmark and relied solely on public transportation and my bicycle, as it truly was the easiest and often fastest way to get around. These days, my bike offers both practical transportation to Duke’s campus and an escape from quarantine.
In Henry’s blog “Transportation without Pollution: How America Can Ditch Gasoline”, I was alarmed by the statistic that “over ¾ of workers in the United States drove to work by themselves in 2013, and an additional 10% carpooled”. In contrast, nearly half of all commuters bicycle to school and work in Copenhagen, which boasts the most advanced and widely used network of bicycle lanes in the world. Henry’s blog and my love of biking together inspired me to question our reliance on motor vehicles in the US and think beyond public transportation and car-sharing to a healthier, happier alternative.
The transportation sector is the largest contributor to U.S. greenhouse gas emissions at 31%, and electrifying vehicles alone is not enough to combat this source. Even with Obama-era tax rebates and automakers signaling their shift to electric vehicles (EV), fewer than 1% of vehicles on the road today are electric. Due to slow turnover rates of existing gas-powered cars and trucks, shifting to an entirely electric vehicle fleet by 2050 would require gasoline-powered vehicle sales to halt by 2035, a drastic and somewhat lofty goal. Thus meeting Biden’s ambitious zero-carbon target by 2050 requires economy-wide infrastructure changes — and perhaps creative behavioral shifts in the ways we travel.
In addition to decreasing greenhouse gas emissions, biking could also alleviate health impacts and equity concerns related to our current transportation system.
One 2017 study also estimated that road transportation emissions “cause 53,000 premature deaths per year nationally”, making transportation the largest single contributor to premature deaths from air pollution, disproportionately affecting children, elderly, low-income people, and people of color (Twite). Obesity rates in the U.S. have also become a common, serious, and costly disease, affecting 42% of the adult population and costing an estimated $147 billion in medical costs.,  A different study with over 150,000 participants ages 40-69 found that when compared to driving, bicycle commuting offered the greatest health benefits; an active commute helped middle-aged adults decrease their body fat and meet recommended levels of daily physical activity.
Where does the U.S. stand on bicycle infrastructure?
Following Europe’s example, U.S. cities have greatly increased their bicycle lane investments in recent years.
During the COVID-19 pandemic, electric bicycles also became a key strategy for essential workers and low-income populations to travel, shown through multiple pilot programs around the country. For example, the Colorado Energy Office awarded $500,000 in grants to such programs for essential workers and low-income communities. California’s Clean Cars For All program also allows disadvantaged households to trade in their used cars for a $7,500 voucher towards purchasing an electric bike. Lastly, New York City Mayor de Blasio announced adding 9.2 miles of protected bicycle lanes to Brooklyn, Queens, and Manhattan. The city’s bike-sharing program, City Bike, reported a 67% increase in usage during March 2020 alone.
New York’s mission to spend $1.7 billion on expanding bicycle lanes cited “addressing climate change, unclogging traffic, and promoting exercise” as its main goals. With the surge in cycling rates, U.S. cities could learn from Copenhagen by focusing on safety and comfort. One way to prevent bike accidents is to designate separate, raised bicycle lanes to clearly delineate cyclists from cars. Good biking infrastructure can indeed reduce traffic and road congestion by allowing people to safely and freely pass one another in the bike lane.
In conclusion, increasing investments into smart bicycle infrastructure (separated from roads, clear line markings, room for passing, etc.) can increase people’s confidence in bike safety and increase our national cycling rates. Cities that decrease their commuter dependence on automobiles can also jointly address transportation emissions, citizen health, and equity concerns — while individuals can better enjoy their surroundings, exercise, and get some fresh air.
So to all my fellow classmates, strap on your helmet and let’s go for a ride!
