An expert discusses Sweden’s efforts to get to zero traffic fatalities:
But in Vision Zero, the accident is not the major problem. The problem is that people get killed or seriously injured. And the reason that people get serious injuries is mainly because people have a certain threshold where we can tolerate external violence, kinetic energy. And we know quite well now how much violence we can tolerate.One of the major things with Vision Zero now is to put that more explicitly on the table. It’s like if we’re talking about the environment, and you know you have a certain threshold when it comes to poison, or whatever. You can tolerate up to a certain level. So it’s not just to stop the traffic. You can actually allow traffic. But if you have places in your system where you have unprotected road users and protected road users, according to Vision Zero you can’t allow a higher speed than 30 kilometers per hour [18.6 mph]…
I will say that enforcement plays of course a role in Sweden, but not so much. We are going much more for engineering than enforcement. If you have a very dedicated police staff and they think it’s the most important thing, then you can be quite effective working with police. But I don’t think you will get a safe system. You will reduce risk, but you will not achieve a safe system.
What about camera enforcement?
We are doing it, but in a different way. First of all, it is a national policy. We have both rural and urban areas, and we work with both. And when it comes to safety cameras, which is what we call them, we have put them on most rural roads. We have one of the largest safety camera systems in the world, per population.
But they are not catching people — it’s nudging people. So we put up the cameras on a stretch, and we tell everyone, OK, now you’re going in this area, and in a friendly but firm way we say you have to keep the speed in this area because we have a history of crashes.
It sounds like this would create some interesting discussions in the United States: do we really want to nudge drivers in such directions or do we truly think cars and vehicles should the rulers of the road? Right now, many of our roads are geared toward helping drivers get from Point A to Point B as fast as they can. But, safety is an important issue and one that concerns a lot of people given the number of vehicle deaths.
