There's a nice "instructional" video about rising bollards on YouTube:<br><br><a href="http://www.youtube.com/watch?v=WEbmJi3ROKk">http://www.youtube.com/watch?v=WEbmJi3ROKk</a><br><br>Enjoy.<br>80n<br><br><div>

> In Denmark and the Netherlands (at least) we have a contraption called a<br>> bus sluice - a hole in the road too wide for small cars, but navigable<br>> by buses and other wide vehicles - for pictures, see:<br>

<br>> orthogonal line across the road (in red, perhaps?).<br>><br>> Another common feature in Denmark (Copenhagen, at least) is an<br>> equivalent "bike sluice" - a road blocked by a fence with holes wide
<br>> enough for bikes to pass, but not cars. Until now, I've tagged these by<br>> breaking the way in two and inserting a very short cycleway between<br>> them, but IMO it should really be a node feature as well. Any thoughts
<br>> on this? An orthogonal line across the road the same color as a<br>> cycleway?<br><br>We have similar arrangements here in Cambridge, and elsewhere in the UK. In<br>Cambridge, instead of a hold in the road, they use a rising bollard which a
<br>transponder on the bus lowers to let it through (In Oxford, they just put a<br>sign up saying 'buses only' or some such). In Cambridge these bus gates all<br>have cycle bypasses. In at least one case, the restrictions depend on time
<br>of day (bollards are lowered at other times).<br><br>We also have the cycle gaps you mention. Further, we have streets which are<br>one way for only the few metres at the end, with a cycle gap to allow<br>cyclists to bypass the no entry (a 'cycle plug').
<br><br>So far I have represented these as follows (I did them this way so they show<br>up on the rendering; I noted we already have tags to determine allowed<br>access permissions for buses (psv) and the like):<br><br>Bus gate: three ways linked to two nodes (close together). The ways on the
<br>outside are highway=cycleway and the one on the inside is<br>highway=unclassified or whatever and access=no psv=yes. To make it clearer I<br>have sometimes used highway=service to distinguish it from the roads at<br>either end. Example in the middle of:
