Cameras to be installed at dangerous Sarasota intersections

Do you believe installing cameras that automatically ticket red light runners will reduce accidents and fatalities?  Click on this link to read a Sarasota Herald Tribune (10-19-10) article about how cameras are to be installed at the 10 most dangerous intersections.  Some cities are installing cameras only at the busiest intersections, but this has provoked the charge that they are just money-making machines.  Sarasota is trying to avoid this objection and also concerns about drivers having points added to their record (they won't).  Some studies suggest accidents actually increase when there are cameras present, though the accidents tend to be rear-enders rather than t-bone (which are more fatal).  Is installation of these cameras a good idea?  (asked by someone who has to cross 41 on a bicycle every day).
