In data modeling terms, displaying a speed data overlay requires
"snapping speed recordings to OSM street
data" (giving ways a 'speed' attribute) - both operations are
complementary, not alternative.<br>
<br>
According to your message, a graphical rendering of Openstreetmap
ways and traffic data mashed up in a browser by joining on an OSM ID
implies a derivative database. If it is, then I understand how some
may avoid using Openstreetmap data for fear of virality.<br>

According to these definitions, because no alteration of
Openstreetmap data takes place, adding a 'speed' attribute to
Openstreetmap ways produces a Collective Database, not a Derivative
Database. Therefore Share Alike does not apply.<br>
