Pedestrian safety

The Most Dangerous Thing You Do Every Day

Three hundred thousand people are killed every year simply walking near roads. That's roughly the population of Pittsburgh or Cincinnati, wiped out annually because they were on foot near vehicles. The World Health Organization is blunt about this: these deaths are not inevitable. They are predictable, and they are preventable.

Yet we keep dying.

What makes this statistic particularly striking is how ordinary the activity is. We're not talking about extreme sports or industrial accidents. We're talking about crossing the street, walking to the store, stepping off a curb. The mundane act of being a pedestrian has become one of the most dangerous things millions of people do every single day.

Who Gets the Blame?

The American Automobile Association, that organization known for helping stranded motorists and publishing road trip guides, takes an interesting position on pedestrian deaths. They say that drivers and pedestrians share responsibility for safety. This sounds reasonable enough until you learn the history behind it.

This framing of "shared responsibility" was deliberately established in the early twentieth century by the American automobile industry lobby. As cars proliferated and traffic deaths skyrocketed, the industry faced a public relations crisis. Their solution was elegant and self-serving: shift some of the blame from the people operating multi-ton machines to the people on foot who were being struck by them.

Before cars dominated American streets, the concept of "jaywalking" didn't exist. Streets belonged to everyone—pedestrians, horses, children playing, vendors selling goods. The word "jaywalker" was invented by auto industry advocates, using "jay" as slang for a country bumpkin who didn't know how to navigate city streets. It was a deliberate shaming tactic to make pedestrians feel responsible for their own potential deaths.

Today, about twenty percent of pedestrian fatalities in the United States are officially linked to jaywalking—defined as improperly crossing a roadway or intersection. But this statistic deserves scrutiny. When we design streets that take a pedestrian forty seconds to cross ten lanes of traffic, is crossing outside the designated zone really improper behavior, or is it a rational response to infrastructure that ignores human needs?

The Physics of Getting Hit

Most pedestrians are injured while crossing streets, and most of those who die are killed at night. The mechanics of what happens when a car strikes a person are grimly predictable.

Picture an adult walking across the street. A car approaches, traveling at typical urban speeds. The bumper makes first contact with the pedestrian's legs or knees. This impact accelerates the lower body forward while the upper body, following Newton's laws of motion, stays relatively still for a split second. The result is that the pedestrian's upper body rotates toward the vehicle.

Then comes the secondary impact. The pelvis and chest slam into the hood. The head, still carrying all its forward momentum plus the force of rotation, swings toward the windshield. By the time the head makes contact with the glass, it's traveling at roughly the same speed as the car was moving.

Finally, the victim falls to the ground.

This sequence explains why vehicle speed matters so much. A minor increase in speed doesn't just raise the likelihood of a crash happening—it dramatically worsens the injuries when it does. The energy of impact scales with the square of velocity, meaning a car traveling at forty miles per hour delivers four times the force of one traveling at twenty miles per hour.

The Geography of Death

If you want to understand pedestrian safety in America, look at a map. Five states account for nearly half of all pedestrian deaths: Arizona, California, Florida, Georgia, and Texas. These are, not coincidentally, states dominated by car-centric urban design—sprawling cities built around highways, wide arterial roads, minimal public transit, and hostile conditions for anyone not inside a vehicle.

The numbers tell a damning story when you compare countries. In 2016, the Netherlands had 2.6 pedestrian fatalities per million residents. Sweden had 4.3. Germany had 6.0. The entire United Kingdom had 7.1.

The United States? 18.5 deaths per million people.

Americans are roughly seven times more likely to die as pedestrians than the Dutch, three times more likely than Germans. Only a handful of developed nations fare worse—Poland at 22.9 and Romania at a staggering 36.3 deaths per million.

What makes this disparity so frustrating is that we know what causes it. The Dutch didn't achieve their remarkable safety record through luck or cultural superiority. They achieved it through deliberate choices about how to design cities and streets.

The SUV Problem

Something changed in the American pedestrian death rate starting in the early 2010s. After decades of gradual improvement, the numbers started climbing again. Researchers have identified several potential culprits: population growth, drivers distracted by mobile phones, poor street lighting, increases in alcohol and drug use, higher speeds.

But one factor stands out: the rise of the sport utility vehicle.

SUVs and light trucks have fundamentally different physics when they strike pedestrians. A traditional sedan's low hood means the initial impact catches an adult at knee level, and the victim's upper body falls onto a sloping surface. An SUV's tall, flat front hits an adult at hip or chest level, delivering force directly to the body's core before the victim is thrown forward or knocked down.

The increasing size of American vehicles has another insidious effect: larger vehicles have larger blind spots. The hood of some modern trucks sits so high that an adult of average height standing directly in front of the vehicle cannot be seen by the driver at all. Children are even more invisible.

We've essentially created machines optimized for killing pedestrians and then marketed them as family-friendly transportation.

The Roads We Build

The design of streets and roads determines pedestrian safety more than almost any other factor. And the uncomfortable truth is that most American roads are designed as if pedestrians don't exist.

An assessment of roads across multiple continents found that eighty-four percent lack pedestrian footpaths entirely, even in areas where speed limits exceed forty kilometers per hour (about twenty-five miles per hour). These aren't rural highways—they're roads where people live, work, and need to travel on foot.

The features that make roads "efficient" for cars are often precisely what makes them lethal for pedestrians: wider lanes that encourage higher speeds, roadway widening that creates longer crossing distances, multiple traffic lanes that require pedestrians to track vehicles coming from multiple directions, and designs optimized for vehicle throughput rather than human safety.

Arterial roads—those major streets that carry traffic through cities—are particularly dangerous. They often feature high speed limits, no sidewalks, few crosswalks, and long distances between safe crossing points. Yet they frequently pass through commercial areas where pedestrians need to go.

Some cities have acknowledged this design failure and made dramatic changes. Freiburg, Germany, a city of roughly fifteen thousand people, lowered speed limits to thirty kilometers per hour (about nineteen miles per hour) on ninety percent of its streets. The results speak for themselves: twenty-four percent of daily trips in Freiburg are made on foot, twenty-eight percent by bicycle, twenty percent by public transit, and only twenty-eight percent by car.

Zero Is Possible

In 2019, both Oslo and Helsinki achieved something remarkable: zero pedestrian deaths for the entire year. This wasn't an accident or a statistical fluke. Both cities had implemented comprehensive policies to discourage car use and increase safety for people on foot.

The approach is called Vision Zero, a strategy that originated in Sweden in the 1990s based on a simple ethical premise: no loss of life in traffic is acceptable. Vision Zero doesn't aim to reduce deaths to some tolerable level. It aims for elimination.

The strategy requires accepting an uncomfortable truth: humans make mistakes. Drivers will sometimes be distracted, tired, or impaired. Pedestrians will sometimes misjudge crossing times or fail to see approaching vehicles. If mistakes are inevitable, then the system must be designed so that mistakes don't result in death.

This means lower speeds, because crashes at low speeds are survivable. It means physical infrastructure changes—narrower lanes, raised crosswalks, pedestrian refuge islands—that make dangerous behavior difficult or impossible. It means accepting that traffic will move more slowly if that's what's required to prevent deaths.

American cities have had mixed results with Vision Zero. New York City has seen meaningful reductions in pedestrian deaths since adopting the framework. Los Angeles has largely failed. The difference often comes down to political will—whether leaders are willing to prioritize pedestrian lives over traffic flow and driver convenience.

The Language of Blame

When a pedestrian is killed by a vehicle in the United States, pay attention to how the crash is described. Journalists commonly report that the pedestrian "darted" into the road. This language comes directly from a National Highway Traffic Safety Administration manual that police use to categorize crash circumstances.

The policy director for the League of American Bicyclists examined federal crash data from 2017 to 2021 and found something remarkable: according to official reports, one hundred fifty pedestrians over the age of seventy-five had "darted" or "dashed" into the street before being killed.

Picture that for a moment. Picture a seventy-eight-year-old grandmother darting anywhere.

The language we use shapes how we understand the problem. When we describe pedestrian deaths using words that imply sudden, erratic, unpredictable behavior by the victim, we're participating in the same blame-shifting that the auto industry pioneered a century ago. We're making the death seem like the pedestrian's fault rather than a predictable consequence of how we've designed our streets and vehicles.

The Dark Months

In Europe, pedestrian deaths follow a striking seasonal pattern. Only six percent of annual fatalities occur in April, while thirteen percent—more than double—occur in December.

The reasons are complex but not mysterious. December brings shorter days and longer darkness. People walk more in shopping districts during the holiday season. Weather conditions reduce visibility and make surfaces slippery. Drivers may be more likely to be impaired by alcohol at holiday gatherings.

But the seasonal pattern also reveals something important: pedestrian deaths aren't random. They cluster in predictable times and places. They happen for identifiable reasons. If we can predict when and where people will die, we can prevent it—if we choose to.

What Safety Looks Like

The Traffic Injury Research Foundation describes pedestrians as "vulnerable road users" because they lack the protection that motor vehicle occupants have. There are no airbags for people on foot, no crumple zones, no seat belts. When a collision occurs, the pedestrian's body absorbs all the energy.

This vulnerability is why the recommended maximum speed in residential areas and places with heavy pedestrian traffic is thirty kilometers per hour, about nineteen miles per hour. At that speed, a pedestrian struck by a vehicle has a roughly ninety percent chance of survival. At fifty kilometers per hour (thirty-one miles per hour), survival drops to about fifty percent. At sixty-five kilometers per hour (forty miles per hour), survival is unlikely.

Traffic calming measures—speed bumps, narrowed lanes, raised crosswalks, roundabouts—work by making it physically difficult to drive fast. They remove the decision from drivers and build safety into the infrastructure itself. This approach acknowledges that humans are fallible and designs around that fallibility rather than hoping it won't occur.

The Fear Factor

Research has documented something that traffic safety statistics don't capture: urban crime, or even the mere perception of crime, severely affects pedestrians' mental and physical health. People who don't feel safe walking in their neighborhoods don't walk. They drive instead, or they stay home.

This creates a vicious cycle. Fewer pedestrians mean less "eyes on the street," the informal surveillance that comes from people simply being present in public spaces. Less activity makes streets feel more dangerous, which discourages more pedestrians, which makes streets emptier and more dangerous still.

Inter-pedestrian behavior matters too. Crowded sidewalks require constant negotiation—people adjusting their paths, making eye contact, signaling intentions. When this social choreography breaks down, through distraction or aggression or simple crowding beyond capacity, pedestrians become dangers to each other even without vehicles involved.

A Preventable Tragedy

The global toll is almost incomprehensible: more than two hundred seventy thousand pedestrians killed on the world's roads every year. Pedestrians constitute twenty-two percent of all road deaths globally, and in some countries, that figure reaches two-thirds.

Every one of those deaths represents a predictable, preventable tragedy. We know what causes pedestrian deaths. We know how to prevent them. We know which infrastructure changes work. We know which speed limits save lives. We have examples of cities and countries that have dramatically reduced pedestrian deaths or eliminated them entirely.

The knowledge exists. The solutions exist. What's often missing is the willingness to prioritize pedestrian lives over the convenience of drivers and the throughput of traffic.

Walking is the most fundamental form of transportation, the one that requires no equipment, no fuel, no license. It's how humans have moved for hundreds of thousands of years. The fact that we've made it deadly—and that we've managed to blame the victims for their own deaths—says something profound about our priorities as a society.

But nothing about this situation is inevitable. The three hundred thousand annual deaths are a choice, not a natural law. We can choose differently. Some places already have.
