Airspace Structure; Procedure
I was Pilot Monitoring on Aircraft X. The departure and cruise phases of flight were normal. The Pilot Flying briefed all of the appropriate items for the approach into ROA prior to our descent. We had discussed the mountainous terrain in the area and how we were going to request vectors to final for Runway 24. ATC had no issues with our request for vectors so they gave us turns for a base leg and a descent to 4;000 feet. I cannot remember exactly how far our base leg was from the runway but I believe it was in between HIBAN and PROSE. In anticipation of our base to final turn we had flaps 9 and gear down. At that point we had not left 4;000 feet and had not called the field in sight. As we were crossing over the mountains; the aircraft gave us a 'terrain terrain.' Since it was daytime and all of the terrain in the area was in sight and not a factor; we continued the approach. We then called the field in sight and landed safely. I believe we had over 1;000 feet clearance at the time of the incident.Aural alert of terrain.The aircraft thinking we were too close to terrain.Continued the approach visually without incident.A possible solution could be to provide flight crews a suggested path to follow when arriving into ROA during day VMC. We could have requested vectors for the full RNAV approach but that may have caused us to be placed too far out on the approach unnecessarily. We planned on receiving vectors and delaying our descent from 4;000 feet until we passed the terrain intentionally to avoid an aural alert from the aircraft. Another possible solution would be to cross over that terrain a little higher and either descend faster to reestablish or overshoot final slightly where there is no terrain in order to reestablish on final on glide path.
Air carrier Captain reported receiving a terrain warning on approach into ROA.
