<div dir="ltr"><div>I've pondered this without conclusion, yet.</div><div> </div><div>Unfortunately it's a bit complicated, since length and width of vehicle, width of barrier and width of path all come into play.</div>
<div> </div><div>You could probably calculate it for "standard" bikes by drawing a ?0.7m straight path through the barrier and then calculating the degrees of deviation from straight that requires. But that's a bit fiddly and doesn't really help you for non-standard bikes.</div>
<div> </div><div>Maybe:</div><div>barrier:bicycle=feet-up (for ones where with practice you can get through without putting your feet down)</div><div>barrier:bicycle=feet-down (for ones where you have to put your feet down but don't have to lift and move wheels sideways)</div>
<div><div>barrier:bicycle=wheel-up (for ones where you have to lift and move wheels sideways)</div><div>barrier:bicycle=dismount (for ones where you have to dismount)</div>barrier:bicycle=bike-up (for ones where the bike has to be lifted completely)</div>
<div>barrier:bicycle=no (for ones where bicycles can't get through at all)</div><div> </div><div>with similar for tandem and bicycle_trailer</div><div> </div><div>Richard</div><div> </div></div><div class="gmail_extra">

</div>They are used to prevent motorcycles from using cycle paths (not as in Germany to prevent bicycles from using footpaths).<br></div>As these are serious obstacles for cyclists I have started tagging them more precisely with, for example:<br>
</div><div style="margin-left:40px">bicycle=yes/dismount<br>wheelchair=yes/no<br>max_width=xxx<br></div></div></div></div>The latter is not correct as "max_width" indicates a legal requirement, normally a road sign, giving the maximum width of the vehicles that may pass the obstacle or road.<br>
</div>Should I use "width" or "est_width" which normally indicates the width of a way? But I want to indicate the maximum width of the normal-length bicycle that I presume would pass the chicane. <br>
</div>
In addition I should tag also:<br></div><div style="margin-left:40px">bicycle_trailer=no<br>tandem=no<br></div></div></div>(which at present have not done)<br><br></div><div>I had hoped to find answers here:<br><a href="https://wiki.openstreetmap.org/wiki/DE:Bicycle/Radwegeigenschaften" target="_blank">https://wiki.openstreetmap.org/wiki/DE:Bicycle/Radwegeigenschaften</a><br>
