Never looked closer to the size of the files. These days storage is cheap so does it really matter? Devices (esp smartphones) have decent processors and calculate quick as well.
On my hard disk Ifound a file in the latest HERE 2015Q3 :"1--read-me--HERE-Navteq HERE ,hsp.txt"
This is similar to the explanation on the NNG website:Files in directory \content\histspeed:
*.HSP - average data for the congestion on the roads in different days of week and time of day. Helps in calculating the route to avoid potential congestion. Do not be confused with TMC (he is in real time)!
Smart Routes
- Chooses the best route based on day of week and time of day
- Considers past speed patterns
- Utilizes
- Traffic patterns (Navteq)
- Speed Profiles (Tele Atlas)
- The additional info is in separate content files (.HSP and .FSP)
The SW feature is included in the base product, but requires additional content and content license.
Note that HSP files have the same function as the FSP files and therefore should not be used simultaneously!
I did not find the equivalent page about HNR files.
AFAIK the HNR provide Primo with a collection of standard pre-defined and pre-compiled routes. The purpose of that is to make it quicker for Primo to work out total routes and execute them, because it doesn't have to compile them each time you set up a total route and follow it. You will still have the complete facility to set up routes and navigate, as you would normally. Keeping this in mind, I do not think the HNR files are really necessary, although calculating longer routes will take some time. But as speedy processors are more common .... ?
