AGENDA TITLE: Plans and Specifications and Advertisement for Bids for Signal Modifications and
Repairs, Cherokee Lane and Lodi Avenue, Cherokee Lane and Victor Road, North
Lower Sacramento Road and Turner Road, and Lodi Avenue and Central Avenue
MEETING DATE: October 4, 1995
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council approve the plans and specifications for the above
project and authorize advertising for bids.
BACKGROUND INFORMATION: This project includes modifying and repairing existing traffic signals
at four intersections. At two intersections, Cherokee Lane and
Lodi Avenue and Cherokee Lane and Victor Road, the traffic signal
plans were modified to increase capacity and/or reduce accidents.
At the other two intersections, North Lower Sacramento Road and Turner Road and Lodi Avenue and
Central Avenue, the work consists of repairs to the existing signals. The signal modifications for the
four intersections are described below:
Cherokee Lane and Lodi Avenue
This intersection is on the City's Intersection Study List, which ranks intersections by accident rate. It
has one of the higher accident rates for signalized intersections. To determine the improvements
needed, collision diagrams were prepared showing the type of accidents. The collision diagrams
showed left -turn phases (green arrows) may be needed for the northbound and southbound
approaches. There are no nationally established rules to determine left -turn phasing. However, there
are four conditions that should be reviewed, including accidents, delay, volume and miscellaneous
features, such as sight problems or large percentage of buses/trucks. At this intersection, three of the
four conditions exist for the northbound and southbound approaches. The plans call for installing left -
tum phases for these Cherokee Lane approaches.
Cherokee Lane and Victor Road
This intersection was reviewed to determine if an additional left -turn lane should be considered for the
Victor Road westbound approach. The traffic volume is over the recommended 300 vehicles per hour
for the westbound approach and, therefore, justifies the dual left -turn operation.
North Lower Sacramento Road and Turner Road
The standard pole located at the southeast corner has been hit a number of times by independent truck
drivers exiting from General Mills. The plans include installing a new pole shaft approximately five feet
east of the existing location and creating a guard post at the existing pole location.

Lodi Avenue and Central Avenue
The loop detectors located in the southern leg of this intersection are no longer operable. This
intersection has been operating under fixed timing rather than vehicle actuation. The plans show
replacing the northbound loop detectors.
Miscellaneous
In addition to the above improvements, wheelchair ramps will be installed at the comers of
Cherokee Lane and Lodi Avenue and Cherokee Lane and Victor Road. At both these intersections,
emergency vehicle preemption equipment will also be installed at all necessary approaches.
The project estimate is $38,000. A specific appropriation recommendation will be made at the time of
award. Construction is anticipated to begin in early December.
