Using osm2po to extract traffic signal in the vertices used to provide the value 1 in the clazz column of the vertex table:

Add vertices costs to postgresql routable network

For some reason I keep getting the value -128 now. Is that supposed to be like this?

  • Can you give me a bit more background info? -128 looks like a barrier. – Carsten Oct 27 '15 at 15:25
  • In the osm2po.conf I've enabled the following line: postp.1.class = de.cm.osm2po.plugins.postp.PgVertexWriter. When I look at the data the only values are 0 and -128. – Yojimbo Oct 28 '15 at 15:42

I could fix the problem by enabling

nodeClazz.1.name=TrafficSignals nodeTagResolver.class=de.cm.osm2po.plugins.routing.TrafficSignalsNodeTagResolver

in the OSM2PO-Routing section

now both barriers and traffic signals (1,-128) are written
