Crucially, this distribution of border points is agnostic of routing speed profiles. It’s based only on whether a road is passable or not. This means the same set of clusters and border points can be used for all car routing profiles (default, shortest, fuel-efficient) and all bicycle profiles (default, prefer flat terrain, etc.). Only the travel time/cost values of the shortcuts between these points change based on the profile. This is a massive factor in keeping storage down – map data only increased by about 0.5% per profile to store this HH-Routing structure!

Третье правило — чемодан нужно собирать «слоями». В прохладных странах погода меняется быстрее, и одна куртка на все случаи жизни не всегда спасает. Поэтому важно положить вещи и на тепло, и на прохладную погоду.
