add new spreadType 'roadCenter' (trac #1758)

[behrisch]

This shall put the centerline in the middle of the bidirectional road regardless of lane differences among the directions.

Example application: correct center line when importing two-way streets from OSM

OSM visualisation doesn't care about the number of lanes. It records the optical center line of the street (which may be different from the center line between the road directions)

• @namdre changed milestone from "2.0.0" to "1.1.0"
• @namdre changed summary from "correct center line when importing two-way streets from OSM" to "add new spreadType 'roadCenter'"
• @namdre changed type from "defect" to "enhancement"

@namdre commented:

this would only work whenever both edges that belong to the road are identifieable

• trivially given when importing bidirectional edges from OSM or Navteq
• computable using the same logic as in NBEdgeCont::guessOpposites

netgenerate now correctly sets the geometry when using option --turn-lanes
