Stay Safe: Jaywalk
By Jon Stonger

It may seem counterintuitive, but jaywalking is in fact the safest way to cross a street.

Parents teach their children many things about being a safe pedestrian as kids that people still abide by in our adulthood:

Don’t run or play in the street.
Good idea.

Look both ways before crossing the street.
Probably the most useful thing you’ll ever learn. I nearly ran over two women in a parking lot who had neglected this basic rule.

Always cross at the corner.
This one is not such a good idea.

Different cities have different environments for pedestrians. In big cities, there is often enough traffic that crossing at the corner with the light may be the only way to get to the other side. That, and there are enough pedestrians to provide safety in numbers.

You don’t really need to worry about crossing the street in a rural area. If there are more than three or four cars driving by in an hour, you must be lost, because where you’re at is not that rural.

Conditions are different in a suburban environment. Since everyone in the suburbs drives their own minivan, very few people walk. If you are seen walking in the suburbs, it will be assumed that you are either exercising, or your car is broken. Since everyone who walks for exercise wears cute coordinated work-out clothes and sticks to cute residential neighborhoods with cute little walking paths, this possibility is often easy to eliminate.

Suppose you are at a major intersection. There are two lanes going in all four directions, plus separate left turn lanes that can turn on green or wait for an arrow. There are four possibilities for crossing.

1. Cross with the signal

If you have a ‘Walk’ signal, then traffic on your left and right will be stopped by a red light. What could possibly go wrong?

Even with a red light, the cars to your left can make a right turn on red. Their right turn will take them directly through your path. These drivers are probably looking towards the oncoming traffic, and not at you. It’s very easy for them to roll forward to get a better view of the oncoming traffic. They might even be talking on a cell phone or wrestling with the kids in the back seat. You are relying on them to see you, and there’s a good chance they won’t.

After you cross the median, there’s even more danger. Cars making a right turn from the lane in front of you are turning on green, so they are also less likely to see you. After all, green means go!

The most dangerous are drivers who are making a left turn on green coming from the street behind you. Their attention is on the oncoming traffic. They are looking for a gap, and trying to find one before the light changes. If there’s a narrow space, they will be accelerating. They might not see you until the last second, and that might be too late.

So unless you’re in a large group of people who are more visible and offer some cushioning in a crash, crossing with the signal is not your best bet.

2. Cross without the signal

This is a little better, but still dangerous. In this scenario, you ignore the walk signal and decide to wait until it’s clear. If you go against the light, then the traffic in front of and behind you is stopped, and the traffic to your left and right is going.

The advantage here is that you’re not relying on the drivers to see you and stop. If it’s clear to the left and the right, you can go . . . until the guy making the right turn on red in the lane in front of you nails you.

The disadvantage of this technique is the number of variables. You have cars coming from 1) your left, including people who plan to turn left or right, meaning they might change lanes while you’re trying to cross, 2) your right, which can be hard to see if there’s a big intersection, 3) people in front of you turning right and 4) if the light changes, people turning left from the lane behind you.

It can be difficult to keep track of who’s going when, and it’s easy to be halfway across when you realize the lane behind you just got a green turn arrow. It is also illegal, as I found out when I was stopped by police in Prague for crossing this way (they let me off when I couldn’t speak Czech).

3. Cross in the middle of the street

This sounds dangerous. You walk thirty or forty feet away from the intersection to the end of the median. You look left. If no one is coming, you cross to the median. Then, you look right. If it’s clear, you cross to the other side of the street.

The disadvantage is that cars are not expecting you to cross there, and they might not be watching for you. Of course, cars are often not watching for you wherever you cross, so this doesn’t seem like a big problem. You’re the pedestrian; it’s your job to watch out for the cars (it’s not who’s right, it’s who’s left).

It is also illegal. Fortunately, jaywalking is a joke law, and can be ignored (as long as there are no cops around).

There are two advantages to this method. First, there are no surprises. Cars aren’t turning, so what you see is what you get. Second, there are fewer variables. You have to worry about one lane at a time. If it’s clear, go. If not, stay. Simple and easy.

I am always pleasantly surprised when statistics support a logical conclusion, and in this case they do. This is a chart of the number of pedestrians hit by cars over five years in New York. The percentage of people hit is organized by location.


% of total % with cause Type
11.7   Unknown
30.9 35.0 Crossing with signal
16.2 18.3 Crossing against signal
2.3 1.7 Crossing with crosswalk, no signal
13.3 9.6 Crossing, no signal or crosswalk
1.0 0.8 Along highway with traffic
0.4 0.3 Along highway against traffic
6.8 5.5 Emerging from parked vehicle
0.1 0.1 Child on/off school bus
1.7 1.4 Child getting on/off vehicle
0.3 0.3 Pushing/working on car
1.6 1.4 Getting on/off vehicle
0.9 0.8 Playing in roadway
10.3 9.2 Other actions in roadway
2.5 2.4 Not in roadway

As you can see, 9.6% of accidents occurred when people crossed on their own (no light, no signal). You are almost twice as likely, 18.3% to be hit crossing at the corner against the light, and you are almost twice as likely as that, 35%, to be hit crossing with the signal!

So here are the revised rules for crossing the street:

Always look both ways before crossing the street.
That’s still a good one.

Don’t cross at the corner.
Go down to the middle of the street and you are statistically safer.

Always assume that a car is going to try to hit you.
You should never assume that a car can see you, or that the driver is paying any attention whatsoever. Just assume they’re aiming for you. I’ve had days where I was tempted to nudge an obnoxious pedestrian, and not everyone has the same self-control. If you can cross the street and no car could hit you even if they tried, then you’re in pretty good shape.

Until you fall through the open manhole.

  1. As an avid cyclist, I couldn’t agree with your last point more. You’ve got no choice but to be on the defensive if you’re not in a vehicle and you want to live.

    However, the data analysis in the study you’ve cited appears to be somewhat flawed. The results are reported as percentages of the total number of accidents. However, I’m willing to bet that far more people cross the street at an intersection than do without a crosswalk, and the data aren’t normalized for this. A more demonstrative statistic would be the percentage of people who have an accident at a crosswalk versus the number of people who cross at a crosswalk, compared with the percentage of people who have an accident while jaywalking versus the total number of people jaywalking. If the crosswalk percentage is greater (statistically speaking, you’d also need to factor in the population size and standard deviation), only then can you say that crossing at the crosswalk is more dangerous.

    As a simple thought experiment, let’s say that there are 1,000,000 pedestrians on the street, and there are 1,000 accidents. Using the percentages above, 35% of those accidents occur at crosswalks (making 350 crosswalk accidents), and 9.6% occur while jaywalking (that’s 96 jaywalking accidents). Let’s further assume that 90% of all pedestrians cross at crosswalks (90% of 1,000,000 makes 900,000 people), and 10% jaywalk (that’s 100,000 jaywalkers). So 350 crosswalk accidents out of 900,000 crosswalkers means 0.039% of crosswalkers get into an accident. Similarly, 96 jaywalking accidents out of 100,000 jaywalkers means 0.096% of jaywalkers get into an accident. Therefore, in this example (using the statistics in the table), you’re actually about 2.5 times more likely to get into an accident if you’re jaywalking than if you cross at the crosswalk!

    Of course, the trouble is that there’s no real way of knowing how many jaywalkers are out on the street, so it would be very difficult to perform this analysis with real numbers. I’m not arguing with your logic in the text of the article, but the statistics in the table don’t necessarily support your conclusions.

  2. Amanda,

    Good point. As the old saying goes, figures don’t lie, but liars can figure. I got the numbers from a pedestrian advocacy group, and without knowing how many people crossed in each situation, you can’t be sure exactly how the numbers play out. Further, the stats were for NYC from 1989-1994, and the statistics may be different in different cities or in different environments. I would be interested to see if there are more complete numbers available.

    Be extra careful riding a bike. I’ve read some stats indicating it’s the most dangerous mode of transportation (per mile traveled). Of course, I’ve seen other sites saying it’s perfectly safe.

    The best advice is just to never leave the house (as long as you don’t slip in the tub, or fall from a ladder, or get and electric shock . . .)
