Here's a summary from the start of July 2007 until mid August of all kinds of crime activity, including traffic related incidents. This is from a website that compiles all the police data throughout San Diego County and is a great source of information that I use for my buyers when they are considering a specific home since you can search by street addresses also. I uploaded the map for your area of interest to one of my websites: http://FileLibrary.MYAASite.Com/Content/12/12509/23986963.pdf
This may fall in to the category of "too much information" for some people, but I think if you compare this area to others in Oceanside, you will find there are fewer incidents of crime that causes a concern.
You may also want to consider the Villages of Rancho Del Oro for renting. Geographically, this is between Oceanside Blvd and Hwy 76 a few blocks east and west of College Blvd.
With that said I would recommend that you speak with the police department there. Also there are many useful tools online. I found this one that is specific to that area: http://www.oceanside-california-living.com/demographics/
Please note that I do not endorse any of these services but only recommend that you include them in your research.
