Dead end segments
Dead ends should all have nodes on the dead end side of the segment. It was possible in older versions of WME to add a road with a dead end and no node. If dead end segment does not have a node move it a tiny bit and WME will automatically add a node. Please note that dead end should not have U-Turn allowed. Please make sure U-Turns on the dead end are Not Allowed.
