I think an arc is created for each part of a road that is connected to other
roads, 
the connections are CoordNodes. Search for arcLength in RoadNetWork.java.

In some comments, a short arc is one with length 0 m,
in other places we say a short arc is shorter than the value passed with the 
--remove-short-arc option.
I think the latter is better. Roads with short arcs sometimes lead to
routing problems.
