In Oslo at least, the crosswalks (usually) have lights if there's an intersection, and since there are no laws against crossing on red you are free to do so, as long as you don't create any dangerous situations. I'd argue that the lights are not to improve traffic flow, but to signal pedestrians that it's safe to cross, something sighted, young or otherwise healthy people often take for granted by just looking both w…
In the US, pedestrian signals do NOT signal when it’s safe to cross. Cars almost always have a green in the same direction, meaning they can turn into you. I almost get run over once a month because of this.
1. There is a pedestrian signal that says to NOT cross, or
2. The traffic signal going in the direction the pedestrian is walking is red.
So if the light is green and the pedestrian signal does not say to not cross, then the pedestrian has the right of way over any cars turning. However, as with anything traffic related, that doesn't mean that a pedestrian can intentionally create an unsafe situation (e.g., start crossing the street as a car is turning).
