SUBJECT: Speed Zone on 26th Street FOR FILING.
Transmitted herewith is a self-explanatory
memo dated December 19, 1907 from the Parking and
Traffic Engineer, subject same as above, together with
copies of the graphs referred to therein.
Briefly summarized, the Traffic Engineer is
recommending, in view of the observed speeds on 26th
Street from Wilshire Boulevard to San Vicente Boulevard,
that the posted speed limit on this sectioh of 26th
Street be increased from 30 m.p.h. to 35 m.p.h. I concur
in this recommendation.
If you concur, it is recommended that the City
Council be requested to approve this increase in the
speed limit and to instruct the City Attorney to prepare
an amendment to Municipal Code Section 3347-A, paragraphs
2 and 3, providing for these increases, as outlined in
the Traffic Engineer's memo.

lir~'.: of 30 MPH to sonic- extent. Over 50% o= the traffic
in ~__is area exceeds the speed limit by more than 5 MPH
whiC_^_ is the maximum tolerance permitted by the police
and acceptable to the courts.
In ~. c,r2a between MOiltai:a and i~1ilSnl r2, OVer ~~% Of
t-:e traiiic exceeds the posted 30 MPri limit, with 35%
above '~olerance limit of 35 MP I.
St ~,, a well-establlsn2a tact that police enforcement
ca be effectively and fairly aio~olied where violations
do no's exceed more than about i5% of total traffic.
~h~'rlen violations exceed this level, the police are sub-
-ct to public criticism both for allowing excessive
speeding tiby those who do observe the law} and for
ci'~ing selected speeders Eby those w'ro receive citations}.
To avoid unjust criticism o= either type, and to ioro-
ioerly recognize what the motorist generally considers
a safe and reasonable s~oeed, posted speed limits are
bes~ established at a 5 mile increment near the 85
~oercen=~ile measured speed. -ln file areas under study
here, the 85 percentile speed, as indicated on the
grapPts, is 38 miles per hour. Accordingly, a proper
posted speed could be either 35 MPH or ~~0 MPH.
