Airspace Structure; Human Factors; Procedure
A CRJ700 checked on departure off of Runway 7L; I then RADAR identified the aircraft and issued a climb to 11;000. During the time of the incident; I had a southbound IFR C182 along V3 that seemed nervous about the upcoming weather. My plan for the CRJ700 was to climb him up above my southbound C182. When the CRJ700 was leaving 4;000; I then issued a vector to 280 degrees to bring him west for his climb. When I realized it wasn't going to work; I stopped the CRJ700 climb to 9;000 to guarantee positive separation. While in the turn I was scanning the weather to the south along my C182 route of flight so I could prepare a course of action for his deviations. When I glanced back over to the CRJ700; I immediately noticed VFR traffic at 6;000 (an IFR altitude); no services were being provided to the VFR traffic at that time. I then immediately gave the CRJ700 traffic; after that I then issued an immediate turn to the left to pass behind the traffic. While issuing the traffic to the CRJ700 no responses were received from him. I then began to notice a descend from the CRJ700. I only could assume afterwards that he was responding to a TCAS resolution. After I noticed the aircraft climbing back up; I then asked if he was responding to a TCAS Alert. His response was 'absolutely.' This situation occurred very early into my rotation on this position. We often have aircraft flying over our airport up and down victor airways at IFR altitudes while squawking VFR. Daytona only has one SID to the north. It happens often when aircraft depart to the East we have to climb and vector them through a lot of VFR traffic. I think maybe a SID would help if we were departing to the east that would take high climbing aircraft offshore so the center can climb them would alleviate a lot of weaving of climbing and descending IFR traffic.
DAB Controller described a TCAS RA event involving an Air Carrier departure being vectored and an unknown VFR overflight; the Reporter suggests development of a SID that provides clearance from know VFR routes.
