Health Benefits[]

Air Quality[]

  • A single driver generates about 10,000 pounds of greenhouse gases every year. Los Angeles ranks #1 in the nation for daily emissions of Nitrogen Oxides (NOx) and Volatile Organic Compounds such as Benzene and 1-3 Butadiene from autos.[1]
  • Cars alone account for more than 625 million tons of carbon dioxide emitted into the nation’s atmosphere each year.[2]
  • You breathe in more pollution when you're in a car than when you're on a bike.[3]
  • Studies here in Southern California show that children living near freeways develop respiratory diseases that affect them for the rest of their lives.[4]
  • At least 8% of LA’s 300,000 cases of childhood asthmacan be attributed to living near a busy street.[5]
  • Pollution from cars is linked to increased rates of autism, asthma, lung disease, bronchitis, emphysema and even a hardening of the arteries.[6]
  • The pollution created just during rush hour creates $31 billion/year in health care costs.[7]

General Public Health[]

  • In Iowa, cycling generates $87 million in health savings every year, and $409 million in Wisconsin.[9]
  • In Copenhagen, every mile of cycling yields $1.30 in health benefits.[10]
  • Employees who commute to work by bike average fewer absences due to illness. Researchers in the Netherlands estimate that businesses could save $35.5 million simply by encouraging employees to bike to work.[11]
  • A study by the University of Wisconsin showed that if residents did half of their short errands by bike, the region would save 1,100 lives and $7 billion in healthcare. [12]
  • Physical activity like biking can save up to $1,175 per person, every year.[11]
  • The average cyclist loses 13 pounds in their first year of cycling.[13]

  • Just 5% of American kids ride a bike on any given day, but California’s Safe Routes to School programs increased bike-riding to school by 200%.[15]
  • For every dollar spent on bike infrastructure in Portland, $5 is saved in fuel costs, health care, and mortality.[16]
  • A four-year study of 822 adults found that found that people commuting to work by car gained more weight on average, even if they engaged in regular exercise, than people who did not commute by car.[17]

Injury Reduction[]

  • Car crashes exact a heavy toll: about 34,000 lives every year. [18]
  • According to the CDC, cars are the #1 cause of death for 5 to 34 year-olds.[18]
  • Biking has been found to reduce women’s risk of wrist fractures.[3]
  • According to the medical journal Injury Prevention, "policies that increase the numbers of people walking and bicycling appear to be an effective route to improving the safety of people walking and bicycling."[19]
  • Research indicates that as bike ridership goes up, crash rates stay flat. A doubling of ridership leads to a 34% reduction of risk per cyclist.[20]
  • In New York, a new pedestrian plaza and bike lanes resulted in a 49% reduction in injuries for all road users.[21]
  • New York's protected bike lanes caused a 35% reduction in injuries on 8th Street and a 58% reduction on 9th Street. [22]
  • Traffic calming in the Bronx reduced pedestrian-involved crashes by 67%, and reductions in speeding of about 30%. [22]
  • Traffic calming around Union Square North in Manhattan saw injury crashes decrease by 26%. [22]
  • Bus and bike lanes on 1st and 2nd Streets in Manhattan caused a 37% decrease in injury crashes. [22]

  • Twenty percent of pedestrian deaths in 2008 occurred in hit-and-run crashes.[24]
  • Car crashes are LA’s third leading cause of preventable deaths, and the #1 cause of all deaths of kids between 1 and 4 years old.[23]
  • In 2010, 51,000 cyclists were injured and 618 were killed in traffic crashes across the country. [25]
  • 14% of traffic fatalities are cyclists or pedestrians. [26]
  • In 2009, cars caused 34,000 deaths and 2,217,000 injuries.[27]
  • A national study showed that 4.2% of drivers sleep while driving and 30% drive despite being too tired.[28]
  • A Baltimore study found that one in six car-drivers pass bicycles illegally.[29]
  • Seventy-two percent of pedestrian deaths in 2008 occurred in urban areas[24]
  • 72% of pedestrian deaths in 2008 occurred on major roads. [24]
  • 58% of bicyclist deaths in 2009 occurred on major roads other than interstates and freeways. [24]
  • Many more bicyclists were killed in urban areas than in rural areas in 2009 (69 percent compared with 30 percent).[24]
  • Sixty-four percent of cyclist deaths are at non-intersections. [24]
  • Cars are particularly dangerous for the elderly: the rates of pedestrian deaths in motor vehicle crashes per 100,000 people are highest for people ages 70 and older. The rate of pedestrian deaths per 100,000 people in 2008 was 61 percent higher for people 70 and older than for those younger than 70.[24]
  • Your lifetime risk of dying in a car is 58 times greater than on a bike. [30]
  • You have twice as much risk of dying from driving as from cycling. [31]

  • Buffered bike lanes even reduce cyclists’ risk of respiratory problems.[78]
  • Buffered lanes in New York tripled weekday ridership, reduced sidewalk riding from 46% to 3%, and reduced speeding from 75% to 20%. The streets were able to accommodate 13% to 9% more commuters. Travel times were virtually unchanged -- a matter of seconds -- and in some cases decreased. [79]

Benefit To Businesses[]

Congestion Relief[]

  • Sixteen separate studies show that when traffic is congested, 30% of cars are simply circling the block for parking.[84]
  • In LA’s Westwood Village, cars have to circle the block an average of 2.5 times before they find a space. Cumulatively, all those circling cars eat up 47,000 gallons of gas (that’s $188,000 at $4/gallon), and enough milage to go to the moon and back four times. [85]
  • Sydney’s bike network is estimated to reduce vehicle trips by 4.3 million per year.[86]
  • Free parking increases driving between 20-40%.[2]

  • And 78% of real estate agents report that their clients are looking for neighborhoods that reduce the amount they have to spend on gas.[59]
  • Los Angeles residents have started calling for car-free streets.[96]
  • When streets are made accessible to people who walk and ride bikes, pedestrian volume increases 23%, and bike volume increases 30%. [97]

Minorities[]

Immigrants are particularly likely to use a bike for transportation. And over the last decade, cycling has increased fastest among African Americans, Hispanics, and Asian Americans.[70]

  • When it comes to bike infrastructure, low-income neighborhoods are particularly disenfranchised: pedestrians there are six times more likely to be injured by a car than people in wealthy neighborhoods.[98]

Bikes[]

  • APBP Bicycle Parking Guidelines (pdf) - a bit old (Spring 2002), but still sound.
  • At the University of Utah, cyclists reduced the school’s car parking needs by over 500 spaces, saving them from having to build a $3.5 million garage.[102]

Funding and Financing[]

- Joseph Henchman, "Gasoline Taxes and Tolls Pay for Only a Third of State & Local Road Spending," Tax Foundation, January 17, 2013. (Proves that state and local roads are subsidized heavily from general tax revenues, refuting arguments that motor vehicle owners primarily fund road construction/maintenance and thus have a superior right of travel on public roadways or a superior claim on financial resources)
