This is a 2009 report on red-light cameras for the City of Temple Terrace, FL, USA that compares the before and after crash statistics of the two RLC intersections in that city. The analysis uses 5 months of pre-RLC crash data compared to 5 months of post-RLC data. The statistics used in this analysis are from the Temple Terrace Police Department which does not specify their Distance-From-Intersection inclusion zone for crashes. This report does not cover injury crashes. There are no data or conclusions in this report that suggest a reduction or increase in fatalities due to RLCs. The results show that crashes at RLC-equipped intersections have increased over 133%.

This is a brief three page report, but the data and statistical analysis are verifiable, the selection of 2 RLC intersections is quite small and only using 5 months of before and after periods weakens the analysis of the data. The report you can download is really just a few sets of data with no analysis included. ABC Action News reviewed an additional 2 months of crash data at the intersections(for a total of 7 months) which showed an 18% increase in crashes since RLCs were installed. More will be posted as our research on this continues.
