A few months ago, I got into a discussion with someone about how to prevent people from crossing to safety.
They had been doing it for years, and the only thing they had done was take a short detour to get to the safety cones.
After I explained the reasoning behind it, the person seemed confused.
“So how do you prevent people to cross to your safety?”
“I don’t know,” he said.
“Well, I have a plan.
I have an algorithm.”
The algorithm is essentially a list of safety cues and things that can be done to make crossing to the cones easier.
One example of this is having a white flag, or sign, near the intersection, which means that pedestrians and cyclists can cross safely.
“When the police say you can cross, I tell you that you can,” the algorithm says.
“This is the safety flag.”
The white flag means the intersection is a safe place to cross.
It also means that a pedestrian or cyclist is not in danger.
The algorithm then tells you what signs you should use and how you should approach them, like a traffic light, red lights, yellow lights, stop signs, stop markers, and so on.
“Then I go through and put them in my head,” the user says.
It is a complicated algorithm, but the basic idea is simple: If you want to prevent crossers from crossing the intersection at all, you have to make it easier for them to cross safely, and this includes making it easy for them not to cross at all.
“The whole thing is basically a checklist,” the app developer, James M., tells me.
“And you can just click through the whole thing, and it’s pretty easy.”
M.M. developed the algorithm because, as a teenager, he saw people crossing the street at all hours of the day.
He decided that he could use it to help him to stay safe.
“Every time I cross the street, I look at the white flag,” he says.
He started out with a simple set of cues.
“You can use a white sign,” he explains.
“A stop sign.”
“And a yellow light.
I think that’s all that you need.”
“You should look out for pedestrians and you should make sure that you are crossing safely.”
The user can add a red light, a stop marker, and a stop sign.
He can also add other safety cues, like the “Cross to safety” sign.
M.T. says that he uses these cues as part of the algorithm in addition to any other cues, and then uses his own mental models to make his decisions.
The user then adds the rest of the safety cues to the list.
When he’s ready to make the crossing decision, he can add the yellow light, stop sign, or red light. M
