Implementing Speedlimits
From Navit's Wiki
- Add a speedlimit attribute to attr_def.h
- Change osm2navit to write the speedlimit attribute if present (and set the appropriate flag as described above)
- Change routing code to query speedlimit if the "speedlimit present" bit is set and add the speed limit to the segment
- In the graph flooding algorithm, use the speedlimit (together with a configurable factor to raise or lower the actual used speed) instead of the default speed for this segment
Already done:[edit]
- Assign a new bit to AF_ for "speedlimit present" (to avoid querying the speedlimit attribute if it isn't present)
