[mkgmap-dev] routing on new devices

Mon Nov 21 18:30:54 GMT 2011

In Basecamp, I tested the routing on one highway=unclassified  and added extra tags in my style file.
Here are some test results:

highway=unclassified
{ set motorcar=no; set motorcycle=no  }  or 
{ set motorcar=no  }   or
{ set motorcycle=no  } or
{ set access=no }

- carpool avoidance NOT selected: 
Road routable for cars, bicycle, motorcycle, foot

+ carpool avoidance selected: 
Road NOT routable for cars, bicycle, motorcycle; routable for foot

{ set mkgmap:carpool=1  }  or
{ set motorcar=no; set mkgmap:carpool=1 }

- carpool avoidance NOT selected: 
Road not routable for cars! 
Road routable for bicycle, motorcycle, foot

+ carpool avoidance selected: 
Road not routable for cars, bicycle, motorcycle; routable for foot

{set motorcar=destination } / {set motorcycle=destination } / {set access=destination } 
Both options are routable for all vehicles EXCEPT cars (not routable); same behaviour as in Mapsource
NB motorcycle = destination doesnt block motorcycles!

{ set access=no; set motorcar=yes } both carpool options are routable for all vehicles
{ set bicycle=no  } both options are routable for all vehicles
{set bicycle=destination } both options are routable for all vehicles
{ set carpool=yes  }  both options are routable for all vehicles
{set motor_vehicle=destination } both options are routable for all vehicles

Conclusion

- some access tags only work for all vehicles if carpool avoidance is used
- mkgmap:carpool=1 can block the road for cars only
- motorcar=destination/acces=destination can block the road for cars, for other vehicles carpool option must be used.

Question: are those observations caused by parameters in the routing that is hardcoded by mkgmap?
