Studies throughout the U.S. show accidents actually increase after red light cameras are installed. From what I read there are fewer "T-bone" crashes and more occurrences rear end "fender benders". Here are a few cities and their reported increases:
Greensboro, N.C. -- 40 percent increase
Anne Arundel County, Md. -- 41 percent increase
Marietta,Ga. -- 51 percent increase
Ontario, Canada -- 15 percent increase
Winnipeg, Candada -- 58 percent increase
