suppose you are using data from external source to estimate actual travel speed
at various places. Then you are assigning travel speed to edges of road network
obtained from OSM. Even if the travel speeds are kept in separate table, to use
them in routing algorithm you need to define some relation between your data
and OSM based network, probably some relation through Id of edges. </span></p><font color="#000000" face="Times New Roman" size="3">

this case the travel speeds are in fact additional attribute of OSM network
edges, even if you keep them in different database table.</span></p><font color="#000000" face="Times New Roman" size="3">

as I understand the ODbl license and community guidelines, I think this kind of
relation creates derivative database, where you have Share-alike obligation (If
you are using it publicly). It doesn’t necessarily mean, your traffic data will
be imported directly to OSM. I think, It means you have to publish them under
ODbl? Am I wrong?</span></p><font color="#000000" face="Times New Roman" size="3">
