Hi all, okay, it took a while because I am busy cleaning up wrong highways... My thinking was this: 1) We want to enlarge sharp angles because we know that a cyclist doesn't care that much about them and typically they are not as sharp in reality. 2) I don't want to enlarge sharp angles at junctions which are only used by cars, esp. I don't want to introduce time penalties at motorway junctions and I don't want to remove time penalties at junctions where a turn restriction is missing and the Garmin algo avoids routing through the sharp angle. 3) The --cycle-map option allows to ignore the problem cases in 2) and (with v4) it also allows to enlarge the angles even more. I guess that this later part is not a good idea, so I've commented that part of the code and changed the documentation of the option a little bit. See also svn log for r3649. Gerd GerdP wrote
Hi all,
sorry, forgot the more important effect of this option: With --cycle-map you can tell mkgmap that different vehicles like car, truck are used as replacements for racing bike, mtb, normal bike or whatever.
I'll review that part again as it doesn't seem to work as expected.

Hi Minko,
if you can't find any, that is also telling me that the option is rather useless.
With --cycle-map mkgmap might produce larger changes when the sum of the road_speed values of two arcs is rather high.
The corresponding part of the patch: + if (cycleMap){ +// if (sumSpeeds >= 14) +// maskedMinAngle = 0x80; +// if (sumSpeeds >= 12) +// maskedMinAngle = 0x70; +// if (sumSpeeds >= 10) +// maskedMinAngle = 0x60; + if (sumSpeeds >= 8) + maskedMinAngle = 0x50; + else if (sumSpeeds >= 6) + maskedMinAngle = 0x40; + else if (sumSpeeds >= 4) + maskedMinAngle = 0x30; + }
Does that help?

I have tested it with --cycle-map What is the difference vs without this option?
