model development.
TASK 6: DETERMINE CURRENT AND FUTURE TRANSPORTATION
NETWORK CAPACITY
Purpose: To develop a thorough accurate, and relevant understanding of the county's
currcnt transportation system's capacity and of the impact of funded projects on this system.
Discussion: An understanding and graphic depiction of the existing and planned network
provides information about current and future t.ransportation ncc. ds and issues. The provision
of funding essentially commits the planned proJect to construction; consequently, the funded
system is often referred to as the committed system. The existing plus the committed system
will serve as a base network system for system alternatives recommendations. By determining
the capacity of existing transportation system and the impact of committed transportation
projects, the consultant will be able to forecast the impact of population changes on the
county's transportation system.
The consultant will prepare a base road network from maps and 6-year Transportation
Improvement Programs (TIP's) received from the various jurisdictions. The base network will
be digitized for modeling purposes and reproducible hard copies w.il[ be prepared. Copies of
the draft network(s) will be distributed to the TAC mcmbcrs for review and approval.
Product: Maps of Kitsap County's Base Year (1990) Transportation Network and Year
2000 Existing Plus Committed (EPC) network.
Subtask 6.01: Develop 1990 Network
Purpose: This task will involve detailing the 1990 network within Kitsap County and
abstracting the network in the rest of the region.'
Discussion: Within the County, the network will include local collector facilities and all
facilities of higher functional classification. Tho functional classification system used within
the County will provide greatcr discrimination among facilities than does the regional
classificalion system. Vehicle and passenger-only ferry connections to Kitsap County will be
included in thc network. Outside of Kitsap, the network generally will include only freeways
and major arterials. A variety of network plots, test paths, assignments, and logic checks will
be carried out to ensure the integrity of the network.
Product: A 1990 network appropriate for input to the 1990 model calibration.
Subtask 6.02: Develop Existing Plus Committed Network
Purpose: To develop an existing plus committed transportation network for travel
forecasts.
Discussion: In this task a network will be p.rep.ar_ed representing the existing network plus all
firmly committed improvements that have a s~gnitJeant impact on system capacity and/or level
of service. These changes includes changes in transit and ferry services. Plots will be
prepared highlighting thc changes in speed and capacity related to committed improvements.
Product: An Existing Plus Committed (EPC) network for input to thc initial travel
forecasts.
TASK 7: ESTIMATE CURRENT LAND ACTIVITY DATA
Purpose: To establish 1990 estimates of population, employment and other key land
activity variables for model calibration.
Discussion: The land use data previously gathered (see subtask 5.02) will be analyzed to
determine current land use activity in Kitsap County; The. Growth Management Act (GMA)
requires a description of land use assumptions usedm estimating travel. Furthermore, land
use is related to population and employment growth. All three of these -- land use, population
and c. mploymcnt data. :- are rcxluired for modeling ti'avel demand. Consequently, the
consultants will use. ex~stmg population,.e.mpl.oy.m..e, nt, and land use information to develop this ·
more detailed description of land use actzv~ty m Kitsap County.
The consultant will modify the Puget Sound Council of Government's (PSCOG)1990
population and employment estimates with information gathered from other sources. These
other sources may include the West Corridor Study, the Office of ]Financial Management, ~nd
the Navy. The consultant will also use recent development data, aerial photographs, and local
knowledge of development projects .to modi.fy land use assumptions.Other sources of
population, employment, and land use ~nformation may also be accessed.
For inter-county travel demand estimation, data from the Pt;COO Forecast will be used for
those counties which are members of the Council of Governments. Data for Mason and
J'efferson Counties will be obtained from the Office of ]Financial Management.
The modifications and assumptions used in refining the population, employment, and land use
data will be reviewed by the TAC for approval.
Product: Technical memorandum on current population, employment, and land use data
for Kitsap County and its cities.
TASK 8: DETERMINE LEVEL OF SERVICE STANDARDS
Purpose: To set the standards for the acceptable levels of traffic congestion on the Kitsap
County's transportation network.
Discussion: Thc Growth Management Act r~uires levels of service standards for all
arterials and transit routes. These standards serve as a ~auge to judge the performance of both
route and entire county-wide system. Furthermore, m order to appropriately forecast the
impact of population growth on the transportation system, the County must decide on an
acceptable level of nctwork volume to as compared to its capacity. The consultant will
provide the County with advice and various criteria for development of level of service
standards. Thc consultant will also provide descriptive examples of previous standard
development by other jurisdictions.
Product: A Technical memorandum describing criteria, choices, and cons .e.:quences of
various potential level of service st,~ndards for Technical Advisory Committee review will be
produced. The consultant will assist the Committee in reaching a decision on the level of
service standard for Kitsap County for use in this plan.
TASK 9: KITSAP COUNTY TRAVEL MODEL
Purpose: To develop a Countywide transportation model for forecasting travel demand
and transportation system needs.
Discussion: Preliminary forecasts reflecting three different levels of projected land use
dcvclopmcnt and th?ir impact on the existing plus committed transportation network will be
dcvelol:e~l. Following analysis and review of the.preliminary forecasts, forecasting procedures
will be refined to support more detailed forecasts ~n specific subareas.
The subtasks involved in the travel forecasting work program are:
(I) Specify Model Structure and Validation Procedures

The activities and products of each Subtask are outlined below.
Product: A Countywide Travel Forecasting Model.
Subtask 9.01: Specify Model Structure and Validation Procedures
Purpose: To specify in detail the structure and methodologies to be used in the travel
forecasting model.
Discussion: The general, approach of the model structure and methodologies has been
determined, but many detads need to be worked out. The gener, a.l approach is to build upon
the PSCOG model structure but also to refine t. he model w~thin K. itsap County. .and to
generalize the model.outside of Kitsap County. This Subtask also will revolve specifying the
procedures and criteria to be used in validation of the model for 1990.
Key details to be addressed in this Subtask include:
Variables to be included in the land use data base
The trip purposes to be modeled in the trip generation and trip distribution stages
The time periods to be modeled in the trip assignment stage
How park-n-ride facilities will be modeled
How ear and passenger-only ferries will be modeled
The extent of zonal disalsgregation to be used in the County and within the subareas at
different stages of analysts
The level of detail to be included in the networks and the link typo classification system
to be used
The key locations for which the model is to provide intersection-level results
If and how to use the PSCOG home-interview data in the model development
The criteria to be used in model validation
Product: A technical memorandum will be prepared specifying the model structure and
validation procedures and criteria.
Subtask 9.02: Obtain/Process PSCOG Data
Purpose: To ob~n several data files from the County.
Discussion: Upon request from the County, P$COO will provide the consultant with several
data files including:
- 1990 and 2010 socioeconomic data
1990 and 2010 networks
1990 and 2010 trip ends by trip purpose
1990 and 2010 trip tables by mode and purpose
These. da. ta will be based on the regional analysis zone system. In addition PSCOG w II
proviUe me parameters used in trip generation and .t. fip distrib'ution..T~, ese data and para~nete'r';
will be the starting point for development of !he Kl~sap model. In thts Subtask the consultant
will convert ~e data to the emm. e/2 modehng pac.kage formats and. prepare the nec.es, sary
network and trip files. PSCOG trip tables will be an ~mportant factor m how zones outside of
Kitsap are aggregated.
Product: The 1990 and 2010 network and trip files of PSCOG data in emme/2 format.
Subtask 9.03: Develop Analysis Zone System
Purpose: To develop a more detailed analysis zone system within Kitsap County and to
develop a more aggregate zonal system outside Kitsap County.
Discussion: In order to provide travel forecasts of adequate detail for the Kitsap County
Transportation Study, it will bc necessary to develop a more detailed (than PSCOG) analysis
zone system within Kitsap. At the same time, zones outside of Kitsap can be aggregated
considerably since detailed results are not necessary in nnrt.~
!nteractlon with K~tsap C.ounty. Whereas Kitsap County ts divided into only 44 analysis zones
m the PSCOG system, it ~s anticipated that the County and Cities within Kit'sa will l~e divided
P
into over 200 zones in this study. The rest of the region will be aggregated from over 500
zones to less than I00 zones.
Design of the zone system will be accomplished in conjunction with the development of the
1990 l?d use dam. base. Anticipat~ future d. evelopm.e, nt.patterns will be an important factor
also. in general, the zone system will be designed to hm~t the number of households and the
number of jobs in any zone to 1000 or less in both 1990 and 2010. In addition, individual
zones will be assigned to major trip generators such as a regional shopping center. Zone
boundaries will maintain compatibility with Census Tract boundaries and, if available, Census
Block Group boundaries.
Product: A zone map showing study zone bounda.ri.'es .a~..d the relationship to PSCOG
zone boundaries. Study-zone-to-PSCOG-zone equivalencies will also be produced.
Subtask 9.04: Incorporate 1990 Land Use Data Model
Purpose: To develop and incorporate the land use data base into the transportation model.
Discussion: Thc travel demand forecasting model will require quantitative measures of the
activity within each analysis zone. Thc P$COG data base includes the following data:
- Population in households and group quarters
Households subdivided by single- and multi-family
- Households subdivided by income quartile
- Employment by SIC groupings
The variables to be disaggrcgated will be specified in $ubtask 9.01. This $ubtask 9.04 will
involve thc actual disaggrcgation (and aggregation in the case of areas outside Kitsap).
Disaggregation will be based on a combination of local knowledge, aerial photos, land usc
maps and field surveys. County and City staff will review the disaggregated data before it is
considered final.
Product: 1990 database incorporating :ill land use variables required as input to the travel
forecasting model.
Subtask 9.05: Develop 1990 Trip Ends
Purpose: Calculation of 1990 trip productions and attractions by purpose.
Discussion: Based on the specification of trip purposes in Subtask 9.01 and thc
disaggrcgated land use data produced in the prewous subtask, 1990 trip productions and
attractions by purpose will be calculated for Kitsap County zones. Outside of Kitsap, trip
productions and attractions received from PSCOG will be aggregated to the study zone system
and trip purpose categorization. The calculation of trip .ends within Kitsap may. involve
adjustment of the PSCOG model parameters based on analysts of the PSCOG home interview
data for Kitsap County.
Product: The 1990 trip production and attraction files for input to the 1990 model
calibration plus trip summaries to be used in the calibration process.
Subtask 9.06: Develop 1990 Trip Tables
Purpose: . T. hi$ .Subta. sk .will involve modifying the PSCOG trip tables to the study zone
systcm and reoaJancmg the tr;p tables to the trtp ends previously calculated.
Discussion: This process will be carried out for. each. trip pu. rpose specified in Sub{ask 9.01.
The resultant trip tables by. p. urpose will be combined into a single trip table representing total
daily vehicle trips on an origin- destination basis.
Product: Daily vehicle trip table for input to model calibration plus related summaries to
be used in the calibration process.
Subtask 9.07: Prepare 1990 Traffic Flow Map
Purpose: Traffic counts collected in Phase I and the 1990 network will be used to prepare
a 1990 traffic flow map.
Discusslon: The traffic flow map willprovi, de the central basis for model validation. The
counts will be entered into the network file with a code indicating the year and source of the
count. Counts will be adjusted to 1990 assuming appropriate annual growth rates and plotted
on the network in bandwidth and numeric form. Bandwidths will be color-coded by count
year/source index. Where multiple counts are available for the same location, these counts
~lill .be prep. ro<:?sed, to p.r.oduce a composite count, but data from th.e. individual counts will
so oe input. ~asea on ..all available count data, a traffic flow map wall be produced for 1990
representing the best available estimate of 1990 dally flows on all freeways and arterials in the
network.
Product: The 1990 dally traffic flow map in the form of an creme/2 network plot of
volume bandwidths and numeric values color-coded by facility type.
Subtask 9.08: Calibrate 1990 Daily Model
Purpose: To adjust the model parameters.
Calibration is the process of adjusting model parameters until the model accurately reproduces
observed conditions or behavior. In this Subtask the travel forecasting technical
memorandum, with 1990 inputs, will be calibrated to the 1990 traffic flows. The calibration
process will involve the following steps:
Assigning daily demand to the network on a minimum oath basis without re~ard tn ~h~
capacity of facilities a. nd comparing assigned, volu'mes to .counts 'a~}~s-~-
screenhnes to determine ~f overall model demand ts in balance with counts. If not, ad-
justments in trip generation and/or trip distribution will be made to bring the model
into balance.
Assigning daily demand to the network on a capacity-restrained basis and comparing
results to counts on a geographic and facility tyl~. basis. If necessa.~., network
changes, volume-delay function changes, or changes m demand patterns will be made
to correct serious deficiencies.
Analyzing model estimates against count estimates on a link-by-link basis to determine
how well the model is producing individual link flows. Where deficiencies are
identified, both the model results and the counts will be evaluated and serious
differences reconciled.
This process will continue until the criteria established in Subtask 9.01 are satisfied or until all
reasonable model adjustments have been made.
Product: A travel forecasting model with the demonstrated capability to accurately
reproduce 1990 traffic flows.
Subtask 9.09: Document Model Development
Purpose: To document all previous modelling procedures.
Discussion: In this Subtask all procedures, parameters, 1990 input data, and validation
results related to the travel forecasting model willbe documented
Product: A technical memorandum incorporating all modelling procedures up to this
point will be produced.
Subtask 9.10: Subarea Model Refinement
Purpose: To refine system analysis to the ~ubarea level.
Discussion: It is anticipated that more detailed analysis will be conducted in each of the four
subareas in a following phase of the study. This will likely require refinement of the
countywide network within the subareas and may necessitate further zonal disaggregation. It is
assumed that further zonal disaggregation will be minimal. A likely refinement within
subareas is the addition of local streets and the revision of zone centroid connectors to produce
more accurate loading patterns. This will be especially important where intersection analyses
are to be performed. Once refinements are made, 1990 assignments will be made and
evaluated to ensure that results are reasonable. ·
Produce: A travel forecasting model capable of supporting more detailed analysis within
the subareas in addition to the initial countywide level of systems analysis.
Subtask 9.11: Subarea Traffic Forecasts
Purpose: To produce a single forecast incorporating the details of all four subareas.
Discussion: Based on the revised model and inputs, a traffic forecast will be prepared
providing more detailed results within each of the subareas. It is assumed that a single forecast
can be produced incorporating details for all four subareas. Plots and summaries will be
produced as appropriate to the needs of the individual subareas. The results of this and the
previous subtasks will be used to develop the subarea circulation plans.
Product: A traffic forecast for each subarea plus appropriate plots and summaries.
TASK 10: PREPARE YEAR 2000 FORECAST AND ANALYSIS
Purpose: To prepare travel demand forecasts and to analyze transportation system impacts
for thc year 2000 for low and high population growth estimates.
Discussion: Preparation of travel demand forecasts and recommendations requires several
subtasks, which arc outlined below. A major goal of this study will be to develop the
transportation element of the County's Comprehensive Plan which satisfies the requirements of
Section 7.6 of the 1990 Growth Management Act. Task 10 provides a "first cut" at the
transportation needs and solutions for the next ten .years and provide the County with
information necessary to balance growth and transportation needs under the GMA.
Product: A Technical memorandum representing both a compilation of the following
Task g subtasks and of Task 9.
Subtask 10.01: Population Growth Estimates
Purpose: To develop estimates of low and high population growth for K/tsap County for
the year 2000.
D~$cusslon: Year 2000 population growth scenarios will initially be based on PSCOG
forecasts. Two. diffe.rent I?opulation growth scenarios -- Iow and high -- will be developed by
the consultant m conjunctmn with the County Staff. These two different population scenarios
will be used to forecast travel demand and to develop potential transportation capacity needs.
The consu!tant will work closely with County staff to estimate the likely impacts of maior
t_r_~.s_po._r?_t~o_n_ ~syste~m changes. (..especial. ly ch. anges i.n vehicle and passenger-only ferry servi~e)

Subtask 10.04: System Solution Alternatives
Purpose: To develop a set of altcmative reCOmmendations under each scenario of
transportation systcm improvcmcnts needed to accommodate projected travel dcmand.~
Discussion: A range of alternative solutions to the impacts of the forecasted travel demand
on thc transportation system will be developed. It is assumed that forecasts will be prepared
for only one level of growth and that no more than three altcrativc systems will be tested.
Only modest revision, if any, to the selected land use forecasts is envisioned. Potential
improvements will include but are not limited to new or expanded roadway corridors; HOV
lanes and priority treatmcnts; local, express, and P&R transit services; new or expanded
passenger or vchicle fcrrics; and demand management techniques (as specified, in the GMA).
This range of solutions may include either specific or conceptual recommendations depending
upon the type of problem thc solution is addressing. If appropriate this set of alternative
recommendations will include a "No Action Alternative".
Candidate solutions alternatives will be developed only to the level of detail rcauired for initial
assessm, cnt at .the countYw, idc level. Selected plots ~md analyses will be proffered as well as
comparisons ot the alternatives one to another.

solutions in the following tasks.
Product: A description of the set of alternative recommendations and their rough cost
estimates.
Subtask 10.05: Funding Capabilities
Purpose: To determine transportation funding options and the financial feasibility of
alternatives.
Discussion Under the GMA, the County is responsible for determining the financial
feasibility of proposed transportation solutions developed in the previous Task. Determining
the feasibility is an important step in developing the final transoortation olan because the
County's ability to fund an alternative will influence its appeal. Th'e result~ of the County s
feasibility analysis may result in a re-examination of both the transportation and land use
~flanternatives and, if necessary, the development of a new set of alternative ~r=.~..~,.~=+;
d, use soluti.ons. (Re-evaluation of such alternatives is beyond the
wor~c program.)
Product: A matrix describing each of the solution alternatives, their estimated funding
requirements and potential funding sources.
Thc products of all Task I0 subtasks will be compiled to form a technical memorandum.
TASK 11: TRANSPORTATION AND LAND USE BALANCE:
Purpose: To meet the requirements of the OMA calling for consistency between land
_ development and transportation system grow. th.
Dlseusslon: The GMA strives to achieve a balance between land Use and transportation
.develop. ment. Consequently, the Act requires that the transoortation nlan hc~th
,s cons,stent with the land use element or the County's com%rehens,%g'p -; '
this entail evaluating the transportation plan's, feasibility, but the reasonableness of the plan
must be considered. If an alternative solution has assumptions which cannot realistically
achieve a land use and transportation system balance, then the alternative is unreasonable. For
example, if under the high growth scenario the only w. ay for the transportation system to
aeeom.m, odate travel demand is through unreasonably high HOV. us~. assumptions, then. the
alternative solution.is unreasonable and unacceptable. The deficlencles of these assumptions
needs to be clearly Identified and discussed.
Because each growth scenario will present a different relationship between land use activity
and transportation system d?velopment, the consultant will evaluate each growth scenario's
land use/transportati.o.n relatlonshtp at a county.wide level to determine if it consistent and
reasonable. Depending upon relevance and wability, the consultant may also choose to
examine the land use/transportation relation at a subarea level.
s~ol°.d,uct:- A. technical...m, emorandum describing each eval.uation of the ability of the
uuon alternatives to reahstlcally achieve a land use/transportation balance will be produced.

TASK 15: PRESENTATION TO COUNTY COMMISSIONERS AND
OTHER PUBLIC OFFICIALS
Purpose: To keep elected officials informed about the transportation plan, so they can
provide guidance during the plan development.
Discussion: It is important that elected officials are involved throughout the transportation
planning process. This task allows for briefing presentations and pr.ogress reports to the
Executive Policy Planning Council and the Board of County Commissioners. The briefing
presentations and reports would focus on:' (I) findings of analyses, (2) discussion of issues
raised by the findings o.r by the community, and (3) any recommendations being developed.

TASK 17 - TRANSIT PRIORITY TREATMENTS
Purpose: Task 17 will identify and assess the potential of transit and HOV priority
treatments for selected corridors in Kitsap County.
Subtask 17.1 Initial Review of Potential Priority Treatments
Discussion: Under this task we will identify locations for potential transit and HOV priority
treatments on major road corridors in Kitsap County. The study area for this identification
will encompass the six corridors identified in the Kitsap Transit letter of October 24th. These
corridors are:
· Winslow Ferry corridor, extending through Poulsbo and branching south to Silverdale
and north to the Hood Canal Bridge;
· Highway 3 corridor through Gorst and branching to Highway 16 south to Tacoma and
Oak Harbor;
· Kingston Ferry corridor, south to Poulsbo and west to the Hood Canal Bridge;
· Both primary access routes serving the Southworth Ferry;
· Access to the Port Orchard passenger only ferries from nearby communities; and
· East Bremenon/Wheaton Way corridor between the Bremerton Ferry and Silverdale.
Identification of potential transit priority treatments along these corridors will initially involve
a prelimina~ review of Kitsap Transit's current route structure, as well as future service
modifications. Working with Kitsap Transit staff, a list of three to five potential treatments
will be identified for each of the six selected travel corridors. Through an evaluation process,
three to four locations for transit priority treatment will be identified for more detailed
assessment (see Subtask 17.2).
Each of the six corridors will be considered in the identification of those sites which exhibit
the greatest potential for achieving transit priority. However, Kitsap Transit staff have
indicated that the Winslow Ferry Corridor will likely be the most feasible in terms of
implementation of priority treatments.
The proposed criteria to be used in the selection of preferred locations include the following:
· Costs;
· Impacts on general traffic circulation and operations;
· Support for other non-single occupancy vehicle (SOV) modes;
· Implementation, including scheduling;
· Community impacts;
· Environmental considerations; and
· Support for Kitsap Transit policies as well as those of other local jurisdictions and state
agencies.
Products: Technical memorandum documenting the results of the subtask. Documentation
will include the three to four sites recommended for further assessment as well as a description
of the major corridors.
Subtask 17.2 - Assessraent of Priority Treatments
Discussion: For each of the three sites identified in Subtask 17.1, an assessment will be
carried out to determine the most appropriate treatment. Potential treatments could include
modifications to roadway and/or intersection geometries, signal preemption, new lane
construction for high occupancy vehicles (HOV), and others as appropriate.
The assessment of potential treatments will take into account their expected benefits and costs.
It will also review potential improvements in terms of over'all feasibility and support for Kitsap
Transit's long term development plan.
Products: Technical memorandum documenting the results of the subtask. This will include
assessment of each site in terms of potential transit and HOV treatment as well as a description
of the recommended treatment at each site.
TASK 18 - PARK-AND-R/DE LOT ASSESSMENT
Purpose: Task 18 will review the park-and-ride program as identified in the long range plan
2
for Kitsap Transit; the review will assess the merits of large lot versus small lot development
within the county.
Discussion: This task will involve a general review of Kitsap Transit's park-and-ride program,
as identified in its long range plan. The review will assess both the size and locations of
proposed new lots. In addition, we will assess two different strategies for future park-and-Hdc
development: (1) a single remote lot that could accommodate a large volume of vehicles, or
(2) a series of smaller lots near the traveller's point-of-origin which provide comparable total
capacity.
The review of these alternative approaches to park-and-ride development will take into account
several factors, including:
· Transit operations;
· Effectiveness in shifting travel from SOV to HOV modes;
· Impacts on local circulation;
· Community impacts; and
· Capital and operating costs.
Products: Technical memorandum documenting the task results. It will include
recommendations regarding proposed new park-and-ride lots as well as findings regarding the
assessment of developing a single large lot versus several small lots.
BUDGET
The estimated budget for the transit related add-on work is presented in Table 1. The project
cost is estimated at approximately $20,000. After Kitsap Transit review of the above scope of
work, modifications can be made to this budget, as appropriate.
