Narrative:
Cleared to cross bayse at 9000 ft. We were descending out of 10000 ft at bayse intersection and missed the crossing restr by 1000 ft. Crossing traffic was at 10000 ft and 5 mi, also at 10000 ft when ATC gave us a TA. A more aggressive descent should have been made to factor in distance flown while slowing to 250 KTS at 10000 ft. Visibility was unlimited, traffic was in sight visually and on TCASII. I gave a warning to the PF that we were getting close to bayse, then proceeded to look up information for the approach, when I looked again, we were at bayse and 10000 ft.
