That's all very well, but how do you explain Castle Ridge Rd? (last map) There are also some loops that have the same weight as dead ends.
Alternative explanation: the municipality surveyors assign prominence-values to roads, based on width etc, which happen to (often) coincide with dead ends being lighter. Google uses these values; competitors don't.
I agree it is a nice effect, both useful and beautiful.
- ry0ohki 16y agoCastle Ridge Rd, while a dead end, also is a trunk that has several branches. It seems like only dead-ends that lead no where else get this width.
- syllogism 16y agoThis makes sense. "Dead end" is probably defined as whether it connects to any other roads. They wouldn't want to define dead-end as whether it connects to any _non-dead end_ roads.
- arantius 16y agoObviously, the emphasis is based on the _length_ of the road, data that is easily accessible. Castle Ridge Rd. is long. Given data laying out connected points, it's harder to say what's an intersection, but easy to say how far apart the points are.
