Question

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?

Answer 1

I could fix the problem by enabling

in the OSM2PO-Routing section

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