- 问: 没看到箭头，只有线条？
- 答: 在JOSM里, 选取菜单Edit, Preference 然后 Display Settings， 选中Direction Arrows.
- 问: One of my way-segments has arrows at both ends, is that correct?
- 答: If there are arrows at both ends, then either 2 ways overlap and use the same nodes, or the way goes back on itself. The way may have been created when inserting nodes into the way, when not deselecting before the next insert.
