WHEREAS, the County of San Joaquin has contacted the City to review the speed
limit on the segment of Guild Avenue north of Victor Road, and
WHEREAS, the length of this segment of Guild Avenue is approximately 2,650 feet
long, with the south 700 feet under the City's jurisdiction; and

the City would adopt the County -proposed limit; and
WHEREAS, on October 6, 1998, the San Joaquin County Board of Supervisors
introduced an ordinance to approve a 45 -mph speed limit on the portion of Guild Avenue
north of our City limits, which is a reduction from the existing prima facie speed limit of 55
mph, and was approved following the public hearing held on October 13, 1998; and
WHEREAS, staff recommends that the City Council approve the 45 -mph speed
limit on the 700 -foot portion of Guild Avenue under City jurisdiction.
NOW, THEREFORE, BE IT RESOLVED, that the City Council of the City of Lodi
does hereby approve the 45 -mph speed limit on Guild Avenue, from Victor Road to

SPEED ZONE REPORT - Guild Avenue
REFERENCE
Speed zone surveys are performed in the City of Lodi following State of California
Department of Transportation (Caltrans) guidelines in accordance with
Section 40802 (b) of the California Vehicle Code. These guidelines are outlined in
Chapter 8 of the Caltrans Traffic Manuaf.
• STUDY
Important factors to consider in determining the speed limit which is most
appropriate to facilitate the orderly movement of traffic and that is reasonably safe
are prevailing speeds, unexpected conditions to drivers, and accident records.
Prevailing Speeds (85th Percentile Speeds) - Reasonable speed limits conform to
the actual behavior of the majority of motorists, and by measuring motorists' speeds,
one will be able to select a speed limit that is both reasonable and effective. Speed
limits should normally be established at the first 5 -mile -per -hour (mph) increment
below the 85th percentile speed. However, in matching existing conditions with the
traffic safety needs of the community, engineering judgment may indicate the need
for a further reduction of 5 mph.
Two radar surveys were performed and the 85th percentile speeds ranged from
39 to 42 mph as shown below:
Guild Avenue Segment Northbound . Southbound
Lodi Avenue to Pine Street 42 mph 41 mph
Pine Street to Victor Road 40 mph 39 mph
Victor Road to 700 feet North of Victor Road NIA NIA
Unexpected Conditions
When roadside development results in traffic conflicts and unusual conditions which
are not readily apparent to drivers, speed limits below the 85th percentile are
warranted. The following factors were considered: roadway design speed, safe
stopping sight distance, superelevation, shoulder conditions, profile condition,
intersection spacing and offsets, commercial driveway characteristics, and
pedestrian traffic in the roadway without sidewalks.
Accidents
Accident records of the two most recent years were considered in determining the
speed zones. Accidents on segments of roadways are classified by their accident
rate. Accident rates are determined by the number of accidents occurring within a
segment of roadway and the traffic volume within that segment. Accident rates are
shown in accidents -per -million -vehicle -miles (ACC/MVM). The accident rates are
0.0 and 4.9 ACC/MVM. The average Citywide accident rate is 4.4 ACC/MVM.

• CONCLUSION
Lodi Avenue to Pine Street
The 85th percentile speeds on this segment are 41 and 42 mph. The 50th percentile
speeds are 36 to 37 mph. The accident rate of 0.0 in this segment is below the
Citywide average and has not changed from the 1993 survey. Based on the
prevailing speeds and the continuing low accident rate, we recommend retaining the
40 -mph speed limit along this segment.
Pine Street to Victor Road
The 85th percentile speeds on this segment are 39 and 40 mph. The 50th percentile
speeds are 34 to 36 mph. The accident rate of 4.9 in this segment is slightly above
the Citywide average and higher than the 0.0 rate from the 1993 survey. Although
the accident rate has increased, it is not high in relation to the Citywide average.
Based on the prevailing speeds and reasonable accident rate, we recommend
retaining the 40 -mph speed limit along this segment.
Victor Road to 70Q Feet North of Victor Road
The south 700 feet of this 2,650 -foot segment of Guild Avenue is under the
City's jurisdiction, with the remaining portion to the north under San Joaquin
County's. The County recently performed an Engineering and Traffic Survey
on its portion resulting in a 45 -mph speed limit. As the portion under the
City's jurisdiction is too short to perform a separate Engineering and Traffic
Survey, staff recommends adopting the County's 45 -mph speed limit on this
segment. The current prima facie speed limit is 55 mph.
The recommended speed limit is shown below:
GUILD AVENUE SEGMENT RECOMMENDED
Lodi Avenue to Pine Street 40 mph (no change)
Pine Street to Victor Road 40 mph (no change)
Victor Road to 700 Feet North of Victor Road 55 to 45 mph
