I already did some research on google regarding this, but it doesn't seem to suit my expectations. I searched with the term "curved road", but it appears that it's just a road with a turning. I'm a bit confused about this.
The photos I have attached here are a dome-like road (white car) and bowl-like road photo (cycling man). Literally, I can't specify the exact shape of these two roads, but this is how they are alike.
