There are two types of subnetworks and the smaller ones seems to be
'one-way subnetworks' which means they are eg. only reachable as
destination or start. But if you would start from a destination-only
subnetwork you'll get 'not found' for all points outside of this
network.<br>

</div>
<div>I printed all the remaining subnetworks.</div>
<div>
<div>edges: 591932, nodes 437420, there were 3496
subnetworks. removed them => 13121 less nodes.
Remaining subnetworks:5</div>
<div>The remaining subnetworks are:</div>
<div>subnetwork start from:
37.32611992939085,-121.9961998312816 size: 24</div>
<div>subnetwork start from:

</div>
<div><br>
</div>
<div>I don't understand why there is still subnetwork
less than 200 nodes.</div>
<div><br>
</div>
<div>I have a look
at 37.32611992939085,-121.9961998312816.</div>
<div>It seesm related with barrier=gate at intersection.</div>
