This table made by highwayrobbery.net, using official documents obtained under the California Public Records Act.
[  ] indicates a footnote.
[1]  Totals are as provided by the City.
[2]  YTD = Year-to-date total.
[3]  Un-used columns are to allow for later expansion of City's system.
[4]  Any figures in red type (or, if you are looking at this table in black and white, the upper figure when there are two or more figures in a cell) are what RedFlex calls Total Violations, or all incidents recorded by the cameras, and due to time limitations may have been posted here only for selected months or locations.  If there is sufficient public interest, the remaining months will be posted.  The figures in black type are what RedFlex calls Notices Printed, and represent the sum of genuine citations issued (those filed with the court) plus any Nominations mailed (not filed with the court, a.k.a. Snitch Tickets).
[5]  Data has been requested but has not yet been received.
[6]  The camera enforcement is believed to be on traffic on the first-named street, but the direction of enforcement (north, south, east, west, thru, left, right) is not yet available.
[7]  City claims it does not camera-enforce the posted "no turn on red" signs.
[8]  Yellow lengthened at ATTG-03L - see Set # 2, below.

This table made by highwayrobbery.net, using official monthly tabulations of citations actually issued.

City of Commerce Docs Set # 2
Longer Yellow at Atlantic/Telegraph Cuts Violations by Two-Thirds

The City lengthened the yellow for the southbound partial left turn at Atlantic and Telegraph, from 3 seconds, to 4 seconds, sometime after March 25, 2009, probably on May 11.  Here are the charts, exactly as pdf'd and sent to me by the City on May 12 and 13.
Old (2001) Chart
New (2009) Chart
Notes for the charts:  The length of the yellow for the southbound partial left turn is given in Column 1, Row E of the table in the upper left-hand corner of page 1.  The date of the change is believed to be May 11, although the 'month' digit of the handwritten "date completed" on the 2009 signal timing chart is not fully formed.

The length of the yellow has a great effect on the number of red light camera tickets issued - the longer yellow at Atlantic/Telegraph cut the number of violations by two-thirds (see the first column in the table, above).  For another example of the effect of a one-second increase in the yellow for a left turn, see the large table on the Mesa Documents page.

"Late Time" Graphs

 The City provided bar graphs of Late Times, etcetera, for all nine cameras.
These graphs track violations recorded, not tickets issued.
Where there is a large number of long Late Time violations in a curb lane, it is believed to indicate heavy ticketing on right turns.
(The curb lane will be the lane with the highest lane number.)


The bar graph above is an example from another city.
