„t FUD AND Item k-1 - "Turner Road and California Street Traffic Study”
.'CALIFCIRNIA was introduced by Staff who apprised the Council that at the
STREET TRAFFIC request of the City Council, the Public Works Department
sum initiated a traffic study at the intersection of Turner and
California and the information fran that study was included on
several exhibits presented by Staff.
Exhibit A as presented by Staff was an accident diagram which
indicates that there were 11 accidents at the intersection
during the last 27 months of which 7 were susceptible to
correction by installation of traffic signals or a 4 -way stop.
During the last 12 months were were 7 accidents of which 6 were
susceptible to correction.
Exhibit B as presented by Staff was the Minimum Traffic Signal
Warrant from State Standards which indicates that the
intersection does meet the minimus vehicular volumes for

Warrant 2, Interruption of Continuous Traffic. It also meets
VV
the warrant for correctable nurber of accidents during a
12 -month period.
gExhibit
C as presented by Staff was the signalization priority
worksheet used by the City of Lodi which indicates Turner Road
and California Street have a total point score of 193. To
place this in context, three other intersections, Ham and
Lockeford, Lodi and Mills, and Lower Sacramento and Lodi have
398 points, 297 points, and 229 points respectively indicating
that this intersection would be fourth or lower on the priority
list for installation of signals.
Exhibit D as presented by Staff showed that the
Turner --California intersection has mi accident rate for 1983-84
of 1.13 accidents per million vesicles. Of the 13
intersections with higher or equal accident rates, 10 are
signalized, and the three intersections - Sacramento and Elm,
Stockton and Elm, Stockton and Lockeford - all have higher
accident rates and are also -2 -way stops. It is highly likely
that these three intersections would alsr, meet the minirnm
requirements for 4 -way stops or traffic signals.
If one considers the six signalized intersections on Lodi
Avenue that do not have a left turn phase, Sacramento,
Stockton, School, Cherokee, Church, and Central, there is an
average accident rate of 2.15. By comparison, the two
intersections on Lodi Avenue that do have left turn phases, Ham
and Hutchins, have an accident rete of 0.85. If. the
installation of left turn phases at the six intersections were
to have the equivalent effect on the reduction of accidents,
the number of accidents would decrease by 55 per year,
considerably rr-)re than the number of accidents :hat might be
eliminated by installation of signals at two or three other
locations that are not now signalized.
While a 4 -way stop is sometimes considered to be a reasonable
alternative to installation of traffic signals, three specific
things should be considered at this particularintersection:
First, the number of vehicles on Turner Road (10,609 ADT) that
are going to have to be stopped in order to allow California
111 Street (1,634 ADT) easy access to or across Turner Road,
second, installation of a 4 -way stop would be detrimental from
a noise standpoint because of the number of trucks that are
going to have to stop and go through the full range of gear
shifting 24 hours per day, and third, the interruption of
tnrough traffic and the costs therein to the traveling public.
This summer the City will be studying all of the high rate
intersections throughout the City to detennine the best way to
use the available funds.
A lengthy discussion followed with questions being directed to
Staff.
Mr. Ernest Bergthold, 512 West Turner Road, Lodi addressed the
Council regarding the matter and spoke to the severity of the
accidents occuring at.the subject intersection.
Following _additional discussion, Council,'on .motion of Mayor
Snider, Olson second, directed that the intersection of Turner
Road and: California Street be placed on the updated, Signal
Priority List for review by 'the Council when funds are
�. . .
available.for additional installations ...u._. w'
