 Totals are as provided by the City.
 YTD = Year-to-date total.
 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 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 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).

 On May 13, 2010 CalTrans lengthened the yellow at Hwy 29/Hwy121. If you have a ticket there, see Docs # 4, below.
 In its June 2011 response to the Mar. 2011 Grand Jury report, the City revealed that in Oct. 2010, and then again in Dec. 2010, it had effectively lengthened the yellow for rolling rights at Hwy 29/Hwy121. Read more in Docs # 4, below.
 Column # 2 was added on 6-19-11. The City prepared two tables for the city council meeting of June 21. Figures in Col. 2 above are from the table the City prepared (linked above) for Agenda Item 28A for the city council meeting of 6-21-11. *The City's table indicated that information for these months was not available at the time the report was written.
 Column # 3 was added on 6-19-11. Figures in Col. 3 above are from the table the City prepared (linked above) for Agenda Item 28B for the city council meeting of 6-21-11. Neither of the reports accompanying the June 2011 tables explains why the 28B table's figures for total right-turn-on-red violations ("RTOR Violations") in April-June 2010 exceed the figures for all violations (shown in Col. 1 above) obtained from the RedFlex-generated table (linked above) covering those months. Nor do we know why the 28B RTOR Violations do not agree with the RTOR Violations in Item 28A. Nor do we know why the number of citations issued at 29/121 during the first quarter 2011, as reported in the RedFlex-generated table (474), is 26% more than the 28B total (377) for the same three months.

 Right turn enforcement at this intersection ended in June 2011, so enforcement is only on the two southbound thru lanes.
In Napa, the percentage of Cites Issued (vs. Events Recorded) is unusually high.

"Late Time" Graphs
The City provided bar graphs of Late Times, etcetera, for all of its cameras, for May 2009 and April 2010.
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 picture above is an example from another city.

The 2008 contract included a "cost
neutrality" clause, whereby the city did not have to pay RedFlex the
full rent if the fines were insufficient to cover the cost. See
Subsection B. of Defect # 10.
Per an article
in the Napa Valley Register, on May 26, 2011 the Appellate
Division of the Napa County Superior Court found Napa's cost
neutrality clause to be illegal.
city council voted 4 - 1 (Techel: nay) to amend the contract to remove
cost neutrality (and the requirement for right turn enforcement), and
to extend the term to Jun. 2012. The staff report for
the June 21 meeting is available here. The

the City disclosed that it
would resume issuing tickets on approx. Aug. 1.
Per an Oct. 8, 2011
Register article, the City was
dismissing 500 of the tickets issued under the old contract. (See
the earlier Grand Jury recommendation, in Set # 4, below.) The
Register said that Capt. Jeff Troendly said that paid tickets in closed
cases will not be refunded. (Note: There may be a way to
re-open a case that was closed/completed less than six months
ago. See FAQ # 26.)

leaving the monthly rent for
each of the cameras at $6000.
In June 2012 the police
chief signed a one-year contract
extension. A July 6, 2012
Napa Valley Register article
revealed that while he got the rent reduced to $1500 on one camera, he
agreed to continue paying $5670 and $6000 on the other three.
Compared to a reasonable target rent of $3000, Napa will pay $86,040
too much, enough to pay for a police officer for a year.

examples of what other California cities pay for
Please note that there could be a contract or amendment later than the ones listed above.
Despite the longer yellow, a
right turn tickets were issued there that month.
In its June 2011 response to
the Mar. 2011 Grand Jury report, the City
revealed that in Oct. 2010, and then again in Dec. 2010, it had
effectively lengthened the yellow for rolling rights at Hwy
29/Hwy121. The June 2011 response said:
"In October 2010 and later in December, 2010,
the City began issuing citations
In that same response, it said it would not
make the refunds recommended by the Grand Jury.
Overall, the City rejected 6-1/2 of the 8
recommendations made by the Grand Jury.

Examination of Attachment

compare 2010 to 2008 (2008 being the last full year before cameras were
installed and 2010 being the only full year with cameras), collisions
at three of the four intersections having cameras, and injuries went up
and down at two. Attachment 3 does show a

2008, before cameras were installed, so cannot be
attributed to the cameras.

other intersections originally considered for cameras, shows that the
big drop is
between 2007 and 2008, before cameras were installed, just like
shows for the intersections where cameras were eventually installed.

"trigger") Speed. From a peer-reviewed academic study:
"Another type of research flaw in some RLC studies is the use of a process measure, such as violations or traffic citations, instead of an actual safety outcome, e.g., crashes or injuries. Unlike crashes, citations are 'endogenous,' meaning officials responsible for issuing citations directly control the number issued."
2011, the police department prepared two tables
for the city council
meeting of June 21. One of the new tables was an attachment to
Agenda Item 28A, the City's (required) response to March's Grand Jury
report. The other new table was an attachment to Agenda Item 28B,
a City staff report recommending that the program be continued.
Two new columns have been added to the big
table (Docs Set # 1, above on this web page), in order to display
figures from the City's new tables alongside
figures from the RedFlex-generated tables we obtained in 2010.

had brought a party of twenty people to Napa. He noted:
some of the responses from the locals:
On Mar. 19, 2013 a Register
article disclosed that
as much as 76% of the City's tickets go to visitors, and that at the
one intersection where the minority of tickets go to visitors,
injury collisions increased 50% over five years.
The article also said:
"[Councilmember] Van Gorder
said if anyone who received a ticket can show him a video
proving they were not hazardously running through an intersection and
received a ticket for slowly rolling on a right turn, he will bring the
matter before the council and vote to end the program."
