Pedestrian Safety

crosswalk sign How big is the problem?

In 2012, 4,743 pedestrians were killed in traffic crashes in the United States, and another 76,000 pedestrians were injured.1 This averages to one crash-related pedestrian death every 2 hours, and a pedestrian injury every 7 minutes.1 Pedestrians are 1.5 times more likely than passenger vehicle occupants to be killed in a car crash on each trip.2

 

Who is most at risk?

  • Older adults
    Pedestrians ages 65 and older accounted for 20% of all pedestrian deaths and an estimated 9% of all pedestrians injured in 2012.1
  • Children
    In 2012, more than one in every five children between the ages of 5 and 15 who were killed in traffic crashes were pedestrians.1
  • Drivers and pedestrians who are alcohol-impaired
    Alcohol involvement for the driver or the pedestrian was reported in 48% of the traffic crashes that resulted in pedestrian death. Where alcohol involvement was reported, 34% of pedestrians killed had a blood alcohol concentration (BAC) of greater than or equal to .08 grams per deciliter (g/dL) and 14% of drivers had a BAC of greater than or equal to .08 g/dL.1

Additionally, higher vehicle speeds increase both the likelihood of a pedestrian being struck by a car and the severity of injury.3 Most pedestrian deaths occur in urban areas, non-intersection locations, and at night.1

How can pedestrians help prevent injuries and deaths from motor vehicle crashes?

  • Pedestrians should increase their visibility at night by carrying a flashlight when walking and by wearing retro-reflective clothing.1
  • Whenever possible, pedestrians should cross the street at a designated crosswalk or intersection.1  
  • It is much safer to walk on a sidewalk, but if a sidewalk is not available, pedestrians should walk on the shoulder and facing traffic.1

Motor Vehicle Traffic-Related Pedestrian Deaths — United States, 2001–2010

To determine traffic-related pedestrian death rates by sex, age group, race/ethnicity, and urbanization level, CDC analyzed 2001–2010 data from the National Vital Statistics System (NVSS). The results of that analysis indicated that the overall, annualized, age-adjusted traffic-related pedestrian death rate was 1.58 deaths per 100,000 population. Persons aged ≥75 years and those categorized as American Indian/Alaska Native (AI/AN) had the highest death rates, and age group differences varied by race/ethnicity. The results suggest that the overall pedestrian death rate could increase with the aging and growing racial/ethnic diversity of the U.S. population. The U.S. Census Bureau projects that the number of persons aged ≥75 years will more than double, from approximately 18 million in 2011 (6% of the U.S. population) to 44 million in 2040 (12% of the population); minority racial/ethnic populations are projected to increase from 116 million in 2010 (37% of the population) to 186 million in 2040 (49% of the population). Strategies to prevent pedestrian deaths should include consideration of the needs of older adults and cultural differences among racial/ethnic populations.

Older adult pedestrian injuries in the United States: causes and contributing circumstances

CDC researchers conducted an analysis of six years of data to examine the characteristics and contributing circumstances of nonfatal older adult pedestrian injuries. Data from the National Electronic Injury Surveillance System—All Injury Program (NEISS-AIP) were analyzed to gather more information about adults ages 65 and older who were non-fatally injured on a public roadway from 2001 to 2006.  Findings showed that, on average, an estimated 52,482 older adults were treated in emergency departments each year for non-fatal pedestrian injuries.  The majority (92.5%) of these injuries were the result of an older adult falling or being hit by a motor vehicle.  More than 9,000 older pedestrian fall-related injuries each year involved a curb—such as an older adult tripping on a curb. While the growth of the older adult population may add to the overall burden of these non-fatal pedestrian injuries, making transportation and mobility improvements—including environmental modifications—can help prevent them.

Why don’t more children walk to school?

CDC researchers conducted a nationally representative, random-digit-dialed telephone survey among English and Spanish-speaking adults, ages 18 and older. Respondents with at least one child (5-14 years) living in the household were asked about the child’s mode of travel to school. Respondents who reported that the child walked to school less than 4 days per week were asked to identify the primary barrier to walking more often.  The most common mode of travel to school was the family car (46%), followed by school bus (40%), and walking (14%).  Among those who did not usually walk to school, distance (70.7%) was the most common barrier, followed by traffic danger (9%).  Children in the South were less likely to walk to school than children in other regions (Northeast, North Central, West). Distance to school was more commonly cited as a barrier to walking for older children than younger children.  Efforts to promote walking to school may achieve better near-term success if focused on students who already live close to school.

Pedestrian fatalities, Atlanta Metropolitan Statistical Area and United States, 2000–2004

Motor vehicle crashes killed almost 5,000 pedestrians in 2005 in the United States. Pedestrian risk may be higher in areas characterized by urban sprawl. From 2000 to 2004, pedestrian fatality rates declined in the United States, but the Atlanta metropolitan statistical area did not experience the same decline. Pedestrian fatality rates for males, Hispanics, and the 15–34 and 35–54 year age groups were higher in Atlanta than in the United States overall. Pedestrian safety interventions should be targeted to high-risk populations and localized pedestrian settings.
