FROM: Planning Department APPROVED
SUBJECT: Contract for General Plan Update Traffic study
suggested Action:
If desired, authorize the Mayor and City Clerk to execute an
agreement with Austin -Foust Associates for a total cost not
to exceed $50,000.
Background:
On February 23, 1987, the City Council initiated General Plan
Amendment 87 -1 which includes a major update to the City's
Land Use and Circulation Elements. As part of this update it
is necessary to prepare an analysis of the traffic impacts
associated with various development intensities being
considered in the commercial areas of the City. It is
proposed to update the City's computerized traffic model and
generate the necessary traffic and circulation information
for consideration by the City Council.
The attached proposal indicates an estimated total cost of
$45,900 over a 5 month period. Staff is working with the
consultant on a final scope of services not to exceed a total
cost of $50,000. An increased budget allocation of $50,000
is also being requested (see agenda item #_).
In addition, $50,000 has been requested in the 1987 -88 fiscal
budget for this project. It is anticipated that a substan-
tial portion of these funds will be required for the addi-
tional environmental work necessary in the General Plan
update including revisions to the General Plan Noise Element.

INTRODUCTION
This proposal outlines the approach and scope of services proposed by
Austin -Foust Associates (AFA) to update the City's computerized traffic model
and carry out a General Plan Circulation Element review for the City of Newport
Beach. The proposal is submitted in response to the Request for Proposal
tendered by the City in May 1987.
Refinement of the City's traffic model and use of the model to update the
circulation element of the Master Plan will represent an important step in the
City's ongoing transportation planning work effort. Today's microcomputer
technology enables jurisdictions such as the City of Newport Beach to apply
sophisticated analysis tools to various planning situations and thereby respond to
land use and circulation issues as they arise.
AFA has been active in traffic forecasting and circulation analyses for
numerous Cities and communities in Southern California and will be able to
support the City's efforts with an extensive background in modeling and
transportation planning. The firm has specialized in developing and applying
state -of- the -art modeling techniques for the specific type of applications being
studied by the City and has particularly emphasized aspects of modeling which
allow both technical and non - technical uses to readily understand and evaluate
the results.
The following
proposal
outlines specific
aspects of AFA's overall
approach to
to this study and
then discusses the scope
of work itself, the time
schedule,
and estimated costs for the
proposed services
outlined here.
APPROAC14
The Newport Beach Citywide Traffic Study will involve two major work
phases. The first is the development of a traffic modeling system that can be
used for detailed circulation analysis work. The second is the circulation
analysis itself, in which the current City circulation plan will be reviewed.
1
i •
Specific aspects of the overall approach proposed by AFA for each of these two
phases are discussed below.
Traffic Model
Traffic forecast models for local jurisdictions have become more readily
accessible as traffic analysis tools since the advent of microcomputer data
processing capabilities. These capabilities have enabled many Cities and
communities to develop the traditional network type of models that previously
were often beyond their resources.
Austin -Foust Associates has been one of the pioneers in establishing local
area modeling as a basic analytical tool for transportation planning. The firm
has developed state -of- the -art modeling techniques, and through their experience
in the application of such models, is familiar with the pitfalls inherent in
carrying out this type of traffic forecasting. Many special features have been
developed by AFA in response to the shortcomings of some of the more
traditional local area modeling procedures.
Since these features are important to this study, they are noted here to
indicate some of the special capabilities that AFA's modeling expertise will bring
to this study.
1. Ease of Use - Many local area models are still somewhat cumbersome to
use despite the use of microcomputer hardware technology. This is generally
related to model structure, where the use of retention factors and internal trip
distributions with subsequent conversions from production- attraction to
origin- destination format require many addition and subtraction steps, all of
which add to the complexity of the model and reduce its overall utility. Under
these circumstances, local area models tend to replicate larger regional models in
complexity, and the main advantage is only the ability to be processed on
microcomputer.
AFA's approach has been to 'streamline' certain aspects of the model, and
0 0
refine the traditionally weaker parts of the process such as trip assignment. An
example of this is the City of Irvine's Transportation Analysis Program (ITAP)
which greatly simplifies the external trip distribution process. It is one of the
features that has made ITAP possible to be easily run on microcomputer by City
staff despite the fact that it models a population of 250,000 in its primary area.
2. Land Use Changes - Local area models are generally extracted from or
related to a larger "parent" model, and external and thru trips are modeled as
cordon to internal or cordon to cordon trips. The cordon volumes are
consequently based on the land use pattern (and resulting trip generation) in
the parent model. Different land uses, particularly if they involve major
changes in intensity and /or changes in resident versus non - residential land use
mixes, will affect the external trips. However, many small area models do not
make any change in the cordons to correspond with changes in land use within
the analysis area. AFA has a special technique to address this problem. It
involves a procedure which emulates the way in which the parent model would
change the trip distribution pattern and hence the cordon volumes in response to
land use changes. This is of considerable importance in the General Plan
review work which includes some land use alternatives that have significantly
different development intensities.
3. Capacity Sensitive Assignments - The use of capacity restraint has been
a traditional part of traffic modeling for some time. However, assignment is one
of the weakest links in an overall modeling chain, and in the local area modeling
context, sophisticated processes are needed to produce the necessary level of
detail such as intersection volumes. AFA has carried out considerable
developmental work over the last several years on incremental capacity
assignment procedures that utilize multiple path assignment algorithms. The
resulting techniques are sensitive to capacities, and are more "stable" than many
other techniques (such as used in UPTS) in the sense that small network
changes do not trigger reactions in the assignment process that are inconsistent
with the degree of the change (minimum path assignments are an extreme
example of this lack of stability).

0
4. Speeds - One of the outputs of a traffic assignment that can be
valuable for evaluation work is network speeds. Most capacity restraint
assignments successively adjust speeds in relation to capacity, but the final
speeds do not necessarily have any meaning outside the assignment process. In
UTPS for example, the final speeds depend on the number of iterations carried
out in the assignment, and are not necessarily related to volume and capacity.
AFA's methodology utilizes an equilibrium speed procedure whereby the final
speeds have a given relationship to volume and capacity, regardless of the
number of iterations. The results can therefore be used for air quality analyses
and for general evaluation purposes (eg, as a level of service indicator).
5. Traffic Share Analyses - One of the important tools of circulation
analyses is the ability to understand the impacts of different geographic areas on
different parts of the network. While most models have the ability to perform
select link analyses, these are often tedious because of the limited number of
links that can be selected and the subsequent processing of the select link data.
AFA has pioneered a special share analysis technique that can enable as many as
100 links to be analyzed during a typical assignment. The output is already
compressed into areas of interest, and can be directly output onto suitable
summary sheets from the small area model assignments.
6. Intersection Analysis - Analysis of intersection turning movements
requires the ability to incorporate user- perceived (and actual) delays or time
savings that occur due to signal coordination, overly high left turn movements,
etc. AFA's assignment techniques enable differential penalties to be placed on
intersection turn movements, these being uniquely determined for each
intersection, rather than as global parameters.
7. Graphical Output - In developing small area modeling tools, AFA has
pursued the "end- user" type of products, and in particular the ability to
i
provide graphical representations of the model output. This is important in
helping planners and engineers interpret the results of the data. Some of the
special features of AFA's small area modeling outputs are as follows:
0 0
a. ADT flow maps (bandwidth volumes)
b. Intersection volume plots
c. Share analysis data
d. Area- specific assignments
e. Direct ICU estimates
f. Graphical display of ICU's
g. Report quality link volume plots (CAD generated)
The model will have applications that will extend beyond the immediate
General Plan needs. For example, trip distributions for specific areas can be
directly extracted in the form of intersection turn movements for use in the
City's TPO program.
Circulation Analysis
An important aspect of this study will be utilizing the traffic model for
circulation planning in the City of Newport Beach. Effective circulation
planning means more than merely running the traffic model to obtain traffic
assignment estimates. Many of AFA's small area modeling features such as those
noted above enable planners to have a better understanding of the traffic
implications of different land use plans. Various select assignments and traffic
pattern analyses will therefore be carried out to help the City understand the
implications of different types and intensities of land use being studied in the
General Plan Review.
MODEL SOFTWARE AND DATA
It is proposed that the software to be used for the modeling work be AFA's
TRANPAC series of programs for microcomputer. This is a highly advanced set
of programs that are not offered for public sale, but are customized and
installed free of charge to Cities as part of a model development and analysis
efforts such as this. While compatible with most of the more popular 'for sale'
packages, TRANPAC offers many advanced features such as noted above, features
that are not available on other packages. The software is easy to use with
minimal training and is designed to allow batch processing which greatly
increases operator efficiency and allows overnight utilization of the microcomputer
equipment. The City of Irvine staff has been using TRANPAC for almost two
years, and the City is considered to be one of the most advanced in Orange
County in terms of carrying out in -house modeling and using the results to
respond to General Plan questions and to provide modeling data for various
traffic studies.
One
of the
features
of AFA's model installation is a development and
validation
report
that not
only describes the
model, but also provides statistical
validation
results
that can
aid in interpreting
forecast data.
Copies of network, trip table, and other pertinent data files will be handed
over to the City at the completion of the study. This will enable the model to
be run on other software if desired and the City will not be dependant on AFA
or AFA TRANPAC for all future forecasting work in the City.
An option that will be available at any time in the future at relatively low
cost is to install the model in -house and train staff in its use.
r
WORK SCOPE
The draft scope of services provided by the City gives a comprehensive
outline of the work to be carried out for this study. The following comments
are therefore largely intended to formulate the steps involved, and to offer any
elaboration where necessary.
PHASE I - TRAFFIC MODEL REFINEMENT
This phase of the work is concerned with preparing the Citywide traffic
model and establishing an initial data base for the circulation work in Phase II.
A base year version of the model will be prepared for validation purposes, and
then forecast year versions developed for use in the circulation analysis. The
following outlines the work tasks involved.
1. Assemble traffic model data base. In this task, the traffic model area
will first be established and traffic analysis zones (TAZ's) defined. Land use
and traffic data will then be assembled. The City will supply zonal land use
data for 1985 and buildout (trend growth), and also assemble existing peak hour
and ADT traffic data. AFA will prepare the information in suitable format for
use in the model (note: traffic count data should be late 1985 or early 1986 to
reflect opening of SR -73 to MacArthur).
The other set of data to be obtained in this task is the OCTAM trip data
for 1985 and 2010, which will comprise the external component of the model.
Two extractions for 2010 will be made, one being the County MPAH and the
other the no -SJHTC alternative.
2. Prepare Traffic Model. The first part of this task will involve coding
the existing circulation system into the computer model graphical link -node
network system. Color coded network plots showing facility types, lanes,
speeds, and link distances will be prepared to aid in network checking.
The traffic model will then be prepared and used to forecast and assign
7
trips to the circulation system. Calibration and validation will be carried out to
reflect actual count data. Comparisons with actual counts will be carried out on
an ADT and a peak hour basis, including intersections ICU's.
The
product from this
phase will be a development
and calibration report of
the type
prepared by AFA
for modeling efforts such as this. In addition to
providing
descriptive data,
the model report will give a
statistical analysis of the
base year
model results and
thereby provide guidelines
on the level of reliability
of modeled data.
PHASE II: GENERAL PLAN CIRCULATION ELEMENT REVIEW
This part of the work will involve various model runs and analyses to
review the relationships between land use and capacity needs on the circulation
system. Table 1 outlines a proposed set of model runs and the following are the
supporting work tasks that will be carried out.
3. Baseline Circulation System Analysis (Runs 2 thru 6). A current plan or
'baseline' street network for 2010 will be developed. It will comprise currently
programmed and expected arterials and collector streets (with assumed lane
configurations) to exist by the year 2010. Land use data will be the Trend
Growth alternative in run 2/2A and then alternatives A thru D for the other
runs.
Congested intersections will be identified from the results of these model
runs, and the results from 2A used to show the regional versus local traffic
contributions to forecast capacity deficiencies. The data from the various land
use alternatives will show how different land uses improve or exacerbate the
deficiencies.
4. No- Corridor Scenario (Run 7) In this task, a run will be made with the
no- corridor version of the model to show the impact on the City's circulation
system. ADT comparisons will be used to show the portions of the circulation
system that are forecast to be deficient under this scenario.

5. Circulation Alternatives (Runs 8 -15) In this task, circulation system
alternatives will be analyzed. Some of the alternatives will respond to specific
issues such as deletion or downscaling of currently planned links, while others
will respond to deficiencies identified in task 3.
An important part of this analysis will involve producing an understanding
of the identified capacity problems. Rather than merely identifying a problem
location, AFA will use the special analysis capabilities of the model to show how
specific traffic patterns and various geographic areas and land uses contribute
to the problem areas. This will assist the overall project team in pursuing both
land use and circulation solutions.
6. Final Traffic Report The product of this phase will consist of a traffic
study outlining the findings of the study. The task will produce the necessary
documentation to satisfy the needs of the General Plan Review.
