<p>Hi Greg,</p>
<p><br>
</p>
<p>my understanding is that Garmin treats 0x0c special to produce the "leave roundabout at the nth ..." hints,</p>
<p>the same for 0x08 and 0x09 to produce the other exit hints. The calculation of the "nth" exit requires special logic,</p>
<p>that's why roundabouts need a special type. <br>

<div>I noticed that I have one linetype (0x0c) for roundabouts and it had many different ROAD CLASS and ROAD SPEED<br>
<br>
# Roundabouts<br>
junction=roundabout & (highway=trunk | highway=trunk_link) [0x2a resolution 18 continue]<br>
junction=roundabout & (highway=trunk | highway=trunk_link) [0x0c road_class=3 road_speed=2 resolution 18]<br>
junction=roundabout & (highway=primary | highway=primary_link) [0x2d resolution 18 continue]<br>
junction=roundabout & (highway=primary | highway=primary_link) [0x0c road_class=3 road_speed=1 resolution 18]<br>
junction=roundabout & (highway=secondary | highway=secondary_link) [0x2e resolution 20 continue]<br>
junction=roundabout & (highway=secondary | highway=secondary_link) [0x0c road_class=2 road_speed=1 resolution 20]<br>
junction=roundabout & (highway=tertiary | highway=tertiary_link) [0x2f resolution 20 continue]<br>
junction=roundabout & (highway=tertiary | highway=tertiary_link) [0x0c road_class=1 road_speed=1 resolution 20]<br>
junction=roundabout & (highway=unclassified | highway=residential | highway=minor | highway=living_street) [0x25 resolution 22 continue]<br>
junction=roundabout & (highway=unclassified | highway=residential | highway=minor | highway=living_street) [0x0c road_class=1 road_speed=1 resolution 22]<br>
<br>
<br>
I also have 2 other linetypes for HIGH SPEED RAMPS (0x09) and LOW SPEED RAMPS (0x08):<br>
<br>
<br>
highway=motorway_link [0x09 road_class=4 road_speed=7 resolution 15]<br>
highway=trunk_link [0x09 road_class=4 road_speed=5 resolution 18]<br>
<br>
highway=primary_link [0x08 road_class=3 road_speed=1 resolution 18]<br>
highway=secondary_link [0x08 road_class=2 road_speed=1 resolution 19]<br>
<br>
<br>
</div>
<div>MY QUESTION:<br>
<br>
</div>
<div>Can I combine all of these different ROAD_CLASS and ROAD_SPEED together using 0x0c and free up 2 routable linetypes? Yes, all the map elements would like the same.<br>
