PROJECT OVERVIE~ AND ~PPROVAL OF PLANS ~D SPECIFICATIONS AND AUTHORI~TION
TO ADVERTISE FOR BIDS - INSTJ~?-?-~tTION OF TRAFFIC SIGNAL AND SAFETY LIGHTING AT
BRYAN AVENUE AND PARK~ LANE (CIP PROJECT NO. 800051)
RECOMMENDATIONS:
It is recommended that the City Council, at their meeting of December 5,
1994, adopt the attached Resolution approving the plans and
specifications for the installation of a traffic signal and safety
lighting at the intersection of Bryan Avenue and Parkcenter Lane and
authorizing the advertisement for bids.
'FISCAL IMPACT:
The Engineer's estimate for this project is $107,000.00. The City
currently has development bonds/cash deposits in the amount of
$87,500.00 for this project. The remainder of funds for this project
are available in the City's Capital Improvement Program budget for
Fiscal Year 1994-95.
BACKGROUND:
At the City Council meeting of November 21, 1994, Councilmember Worley
inquired as to the need for installing a traffic signal at the noted
location. Staff was subsequently directed by the Council to review the
justification for the installation of the traffic signal at this time,
and provide the Council with additionalinformation regarding this item.
DISCUSSION:
This item was previously presented for council consideration at the May
3, 1993 City Council meeting. A copy of the May 3, 1993 agenda item is
attached for your information. As noted in the May 3, 1993 agenda item,
theEngineering Division had completed a Traffic Study (attached) of the
noted location, which addressed the appropriateness of installing a
traffic signal at Bryan Avenue/Parkcenter Lane. Traffic signal warrants
were prepared for the subject intersection and it was determined that
conditions met minimum requirements., to satisfy the Peak Hour Volume
warrant. The Traffic' Study concluded that since the traffic signal
warrant has been satisfied under both existing and future conditions,
traffic signal construction may proceed in a timely manner.
As part of the Traffic Study prepared for this intersection, the
Engineering Division also contacted the City's Community Development
Department and the Police Department to solicit input regarding the
installation of the subject traffic signal. Both City Departments
concurred that a traffic signal was needed at the subject location
(Memorandums attached).
As part of the Conditions of Approval for Tract Map Nos. 13053, 13080,
13094, and CUP 92-044, the applicants of those projects were required.to
pos~ bonds/cash deposits for participation in the future signalization
of the subject ~intersection.~- It should be noted that these bonds had a
five-year term and some of them were redeemed pursuant to Council action
on May 3, 1993. The City currently has cash deposits in the amount of
$62,500.00 and a bond for $25,000.00 (to be redeemed with approval of
Plans and Specifications of this project), for a total development
contribution of $87,500.00-toward funding of this traffic signal
-'project~--tf--tq%e.C~.ty Council determines that this traffic signal is not
needed at this time, {h~these'funds would need to'be refunded to the
respective applicants. -
In reviewing current information regarding conditions at the subject
intersection, is has been found that traffic on Bryan Avenue has
increased almost 10% in this area in the critical peak hour during the
past year. The current 24-hour traffic volume on Bryan Avenue is 12,500
vehicles per day. As identified in the City's General Plan, Bryan
Avenue in this area will accommodate 25,000 'vehicles per day at
bui~dout. Current accident records indicate there have been two
accidents at this intersection between January 1, 1994 and October 31,
1994, which could have possibly been prevented with the installation of
a traffic signal.
· .
Also, Parkcenter Lane is identified in the citY,s Bikeway Plan in the
General Plan as a Class Ii Bikeway, which includes bicycle lanes striped
on both sides of the street adjacent to the curbs. Currently, Class II
bicycle lanes are installed on Parkcenter Lane north of this
intersection and the southerly continuation of these bicycle lanes is
planned. However, there would be a safety concern if the bicycle lanes
were continued along Parkcenter Lane across Bryan Avenue without
intersection controls at the Bryan Avenue/Parkcenter Lane intersection..
The installation of the subject traffic signal would allow for the
future installation of bicycle lanes along Parkcenter Lane between
Bryan Avenue and E1 Camino Real.
This project will provide for the installation of a traffic signal and
safety lighting at the intersection of Bryan Avenue and Parkcenter Lane.
The work will include all labor, material, tools, equipment,
appurtenances and incidentals for the subject project as detailed on the
plans and specifications for this project.
The tentative schedule for this project is as follows:
Authorization to advertise for bids ................. 12- 5-94
First legal advertisement ........................... 12-22-94
Second legal advertisement .......................... 12-29-94
Open bids ..............
............................. 1-17-95
Award construction .................................. 2- 6-95
Commence construction ............................... 3- 6-95
Complete construction ............................... 5-15-95
CONCLUSION:
Traffic signal warrants were prepared for the subject intersection and
it was determined that conditions met minimum requirements for the
installation of a traffic Lsignal. 'Also, current information indicates-
that traffic volumes in the subject area have increased and are expected
to further increase as development in the area proceeds.
If it is determined that the traffic signal is not needed at this time,
then the $87,000.00 in bonds/cash deposits will need to be refunded to
the respective applicants. However, the installation of a traffic
signal at the subject~location would provide the necessary assignment of
right-Of-way to facilitate maximum maneuverability at this intersection
and would further implement the City's Bikeway Plan.

UBJECT: TRAFFIC SIGNAL INSTALLATION AT THE INTERSECTION OF BRYAN
AVENUE AND PARKCENTER LANE
RECOM}4ENDATION:
It is recommended that the City Council, at their meeting of May 3,
1993, authorize the calling in of all existing bonds/cash deposits
for. the signalization of the intersection of Bryan
Avenue/Parkcenter Lane and the deposit of these funds into a
Separate account for the future traffic signal installation at the
subject intersection.
FISCAL IMPACT:
It is estimated that a project for the installation of a traffic
signal at the noted location would cost approximately $120,000.00.
The City currently has bonds/cash deposits in the amount of
'$87,500.00 for this project.
The remaining amount (City's share) of $32,500.00 for
implementation of this project would be considered for inclusion in
the City's Future Capital Improvement Program for FY 93-94.
BACKGROUND:
As part of the.Conditions of Approval for Tract Map Nos. 13053,
13080, 13094, and CUP 92-044, the applicants of those projects were
required to post bonds/cash deposits for participation in the
future signalization of the subject intersection in conjunction
with approval of their.'project.
All of'the existing bonds/cash deposits, totalling $87,500.00, will
soon exPire and will need to be either returned to the project
applicants or used for signal construction. If it is determined
--that a traffic signal is needed at the noted location, the City has
the opportunity to redeem the bonds/cash deposits and deposit the
funds into a Capital Improvement Program account designated for
this project.
DISCUSSION:
The Engineering Division has recently completed a study of the
subject location addressing the need for a traffic signal. As part
of the study, the Engineering Division also contacted the City's
Community Development Department and the Police Department and
received input regarding the installation of the subject traffic
signal; Both City Departments concurred that a traffic signal was
needed at the subject location.
·
traffic signal warrants established by the California Department of
Transportation (Caltrans) and currently found in the Caltrans
Traffic Manual. The study notL only' examined the need for traffic
signalization, at this time, but also investigated' the ~need for
installation of a traffic signal at the noted' location at a future
date.
Traffic signal warrants were prepared for the subject intersection
and it was determined that conditions meet minimum requirements to
satisfy the Peak Hour Volume Warrant.~ Since the traffic signal
warrant has been satisfied under both existing and future
conditions, traffic signal construction may proceed in a timely
manner.
Also, since a majority of the funding for such construction has
already been obligated through development Conditions of Approval,
it is therefore felt that the calling in of the bonds/cash deposits
at'this time is appropriate since they are nearing their expiration
~ate, and the funds should be obligated for construction of the
project.~

Investigation to determine if traffic signal warrants are satisfied for
the intersection of Bryan Avenue and Parkcenter Lane.
RECO ED ACI ON:
It is recommended that a traffic signal be installed at the intersection
of Bryan Avenue and Parkcenter Lane. Since an existing traffic signal
warrant is satisfied, the construction can proceed in a timely manner.
STA NT OF ISSUF_S OR PROBLEMS:
When ~he area in the vicinity of this intersection was being developed,
the Engineering Division of the Pubiic Works Department of the City of
Tustin' conditioned tracts 13080, 13094, and 13053 to install traffic
signals at the intersection of Bryan Avenue and Parkcenter Lane when
actual conditions Warranted the installation. To accomplish this
installation, bonds for the installation were deposited by each tract.
These bonds are almost five years old and must be used to install the
traffic signal or be returned to the developer.
INTRODUCTION AND BACKGROUND:
The installation of traffic signals should be justified by satisfying
established warrants along with conditions that demonstrate the need for
traffic signal control of,traffic right-of-way. The City uses traffic
signal warrants established by Caltrans and currently found in the
Caltrans Traffic manual.
When new development is being proposed, it is the duty of the local
agency (usually a city or county government) to assure that the traffic
impacts of the proposed development are mitigated' Where it is likely
that a traffic signal will be needed, this type of traffic control
becomes a condition of approval for the development. In this case,
bonds for the construction of the traffic signal were collected in lieu
of construction_. '. '.
This study is undertaken in order to determine if the installation of a
traffic signal at the subject intersection is warranted at this time and
if future conditions may warrant the installation at a later date.
_ DISCUSSION AND ANALYSIS:
EXISTING CONDITION
Traffic signal warrants have been prepared for the subject intersection.
Warrant 11, Peak Hour Volume, is satisfied; none of the other warrants
investigated are satisfied. See Table I below:
Table. I
~lurac; 4- ~ Cro~sis~s; 5-P~ ~v¢ Movmumt; 6-Accidcm P-xpesic~c;
7-~y~; 8-combhutioo: 9-Four Hour Volume: 10-Pr.~ Hoot Dchy; ! l-Peak Hoor Volume.
Comment.
The only warrant satisfied is warrant 11, the Peak Hour Volume Warrant.
The major warrants of 1 and 2 are currently not 80% satisfied.
There were two traffic accidents recorded in 1992: one was a right angle
type; the other was a bicycle/car accident caused by the bicyclist when
the bicycle entered the street from a wheelchair ramp.
traffic signal warrants represent the lowest possible threshold at which
a traffic signal could be installed. CalTrans prints the following on
its traffic signal warrant sheets: "The.satisfaction of a warrant is not
necessarily justification for a signal. Delay, congestion, confusion or
other evidence of the need for right-of-way assignment must be shown."
While delay of traffic during the peak hour could be measured to further
determine the need for a traffic signal at this intersection, the delay
warrant cannot be satisfied since part b of the warrant is not met,
which requires the highest volume on the minor street to be at least 100
vph. Presently this volume is 92 vph.
BUILD-OUT CONDITIONS
The subject intersection is located in the East Tustin Ranch Area. In
.~he near vicinitY of the intersection of Bryan Avenue and Parkcenter
Lane, the land uses have been constructed and are occupied, and little,
if any, vacant land is available for future development which could
affect the traffic volume on Parkcenter Lane.
Other areas of the East Tustin Ranch Area are presently undeveloped.
There are future plans to completely develop East Tustin Ranch and
development activity is onTgoing in the area. Thus, full build-out of
the area is highly probable. Therefore,"the forecasted traffic volumes
on Bryan Avenue must be analyzed for traffic impacts at this
intersection.
The build-out traffic volume for Bryan Avenue is estimated in the East
Tustin Ranch. Specific Plan Traffic Study to be 21,000 ADT. The existing
traffic volume on Bryan Avenue is 11,629. The'~kisting traffic volumes
on Parkcenter Lane are 1332 ADT between BrYan Avenue and E1 Camino Real
and 862 ADT between Bryan Avenue and Tustin Ranch Road. No forecast
traffic volumes are available for Parkcenter Lane.
Although little new traffic volume, if any, will be generated on
Parkcenter Lane by the adjacent development, it can be anticipated that
future traffic would be diverted onto Parkcenter Lane due to congestion
and delay at other intersections in the near-by area. A twenty percent
growth factor will be used to calculate the future traffic volumes on
Parkc~nter Lane.
Caltrans has established traffic signal warrants for minimum volume,
interruption of COntinuous traffic, and combination to be used based on
estimated average daily traffic published with the other signal warrants
discussed above. The results are shown in Table II below'
Table II
Future Traffic
Warrant
1 - Minimum Volume
2 - Interruption
of Continuous
Traffic
3- Combination
80% of 1 & 2
Satisfied 94 percent
satisfied
Not Satisfied X X X
1 - 48%; 2 - 94%
Comment.
From the future warrant calculation, the same basic conclusion as the
existing condition can be made: the traffic signal warrant is
borderline; much depends on how much traffic will divert; diverted
traffic may exceed the 20 percent assumption made for the calculation.
With future traffic volumes increasing, it is likely that delay and
traffic accidents will increase. However, with the installation of a
traffic signal, there is a possibility that the number of rear-end type
accidents would be about the same as the eliminated right-of-way
violation accidents.
It has been investigated if the new signal would affect delay given that
the signal would be tying into a coordinated sYstem along Bryan Avenue.
Presently the system is running a 40 MPH coordinated speed and a 70
second cycle length for the existing condition.' A band width of 42
seconds will be needed for. through and left turns at this new
intersection, leaving 28 seconds to service Parkcenter Lane which would
need a minimum of 24 seconds to accommodate pedestrians across Bryan
Avenue.
It was assumed that an 80 second cycle would be needed for build-out
traffic. This cycle length will accommodate a 35 MPH coordinated speed
and will likely be able to service the 24 second pedestrian time needed
for Parkcenter. Any Parkcenter Lane traffic .will.be served by this
amount of time.
RECOM]WF. NDATION:
Given the above existing and future conditions where a traffic signal
warrant has been satisfied, it is recommended that a traffic signal be
installed at the intersection of Bryan Avenue and Parkcenter Lane. As
an existing traffic signal warrant is satisfied, the construction can
proceed in a timely manner.

W. DOUGLAS FRANKS, CHIEF OF POLICE
RESPONSE ON TRAFFIC SIGNALS AT BRYAN/PARKCENTER
Tri-phase signals with protected left turns on east and westbound
Bryan would be recommended from the Police Department's
perspective.
This is primarily due to the relatively high speeds of east and
westboQnd "~traffic on Bryan and the wide road width and center
median which north and southbound traffic on Parkcenter must
traverse while either crossing or turning on to Bryan Avenue in
either direction.
protected left turns for Parkcenter do not appear necessary due to
the lower volume of traffic.
Thank you for the opportunity to respond on this matter. If you
have additional questions, please contact Lt. Bob Schoenkopf.
