AGENDA STATEMENT
City Council Meeting Date: March 11, 1991
SUBJECT: Tri-Valley Travel Forecasting Model
(Report by Public Works Director Lee Thompson)
EXHIBITS ATTACHED: 1) Resolution approving cooperative agreement
2) Agreement
RECOMMENDATION: 1) Adopt resolution approving the cooperative
agreement between the Contra Costa Transportation
Authority, the County of Alameda, and the Cities
of Dublin, Livermore, and Pleasanton.
Z) Authorize budget transfer in the amount of $24,750
Vy from unallocated reserves to the Engineering
operating budget to pay Dublin's share of the
model.
FINANCIAL STATEMENT: The City of Dublin's share for development of the
model is $24,750. There will be future annual costs
for updating the model as well as costs to run traffic
patterns for proposed developments. The annual
maintenance cost is estimated at a total of $8,000 to
$12,000, which would be split among the jurisdictions.
Additional costs to be incurred will include
approximately $5,000 for TJKM to take additional
traffic counts and turning movements, as well as Staff
time for meetings of the Tri-Valley Transportation
Committee technical advisory committee, monitoring of
the study, and for calculating some levels of service
on the transportation network.
The developers using the model to determine traffic
impacts will pay for the cost of the runs plus a
factor to help defray the cost of development of the
model.
DESCRIPTION: The five Tri-Valley cities (Dublin, Livermore,
Pleasanton, San Ramon, and Danville) and two counties (Alameda and Contra
Costa) have entered into a joint powers agreement to work together to attempt
to solve common area-wide transportation problems, both existing and future.
As a first step in this process, it is proposed to share the cost of a local
travel forecasting computer model that will include the freeways and arterial
streets of the various jurisdictions and will be able to predict the
distribution of traffic from new developments.
Once complete, the model will be used to determine levels of service on
selected roadways to monitor traffic impacts on these roads as development
occurs. This is also an element of the Congestion Management Plan (CMP) which
is, in turn, a requirement of Proposition 111 . Proposition 111 raises monies
through an increase in State gas taxes and distributes the money to the
various agencies within California to be used on transportation improvement
projects.
The Contra Costa County Transportation Authority (CCCTA) is the lead agency in
the development of this model and has retained Barton-Aschman as prime
consultants and TJKM as a subconsultant. CCCTA is paying for one half of the
cost of the model through its Measure C gas tax monies as the Contra Costa
County jurisdictions' share of the model cost. The four Alameda County
agencies are proposing to split the remaining one half of the cost into four
equal shares.

EXHIBIT X-
SCOPE OF WORK AND
MILESTONE SCHEDULE
SCOPE OF WORK FOR THE DEVELOPMENT OF THE TRI-VALLEY EMME/2 TRAVEL
DEMAND FORECASTING MODEL
OBJECTIVE
CONSULTANT shall develop a validated Tri-Valley EMIv1F/2 Travel Demand Forecasting Model (Tri-
Valley Model). The Tri-Valley Model shall have an appropriate level of detail to adequately address the
needs of the counties and the Authority,as well as of each individual city,to conduct major traffic impact
studies, environmental analyses, evaluate alternative transportation improvement strategies, and support
the requirements of Propositions 111 and 108.
The Tri-Valley Model will be a nested subset of the Alameda and Contra Costa Countywide models,
which,in turn, are a subset of the regional MTC travel demand model system.The Tri-Valley Model will
be consistent with the MTC models, as well as the Contra Costa countywide and subregional models and
Alameda County models.
The Tri-Valley Model shall be capable of projecting AM and PM peak hour, as well as ADT, forecasts
for the highway network, including major intersection turning movements for 1990(existing conditions)
and the forecast years 2000 and 2010.
APPROACH AND N=ODOLOGY
CONSULTANT shall develop the Tri-Valley Model from the existing Contra Costa and Alameda County
EMIVIFF/2 models. Both of these models have been developed to nest within the MTC regional model and
data base. CONSULTANT shall"focus"model refinement on the "subarea"called the Tri-Valley,which
includes the Town of Danville,the Cities of Livermore,San Ramon,Dublin,and Pleasanton,their spheres
of influence, and selected unincorporated areas of Alameda and Contra Costa Counties, including Alamo
and the Tassajara and Dougherty Valleys, but not Castro Valley.
CONSULTANT shall develop a substantially more detailed zone system and roadway network within and
immediately bordering this subarea. Tri-Valley Model shall provide significant additional detail than is
currently available at the countywide level and shall include minor arterials, selected collectors, and
turning movements at all major intersections for which counts are available. The Tri-Valley Model shall
provide a zonal level of detail equal to or greater than the existing TJKM Tri-Valley model or a level of
detail mutually agreed upon with the jurisdictions.
Cooperative Agreement No. 45.01.00 Exhibit A
Between Contra Costa Transportation Authority and Page 1 of 13
County of Alameda, Pleasanton, Dublin, and Livermore
Task 1: Review Existing Transportation Models and Land Use Requirements
Purpose
The purpose of this task is to review the existing Alameda and Contra Costa Countywide models, and the
existing TJKM Tri-Valley model, to identify differences and determine which model structure to apply
for the Tri-Valley area. This task also involves reviewing the status of the technical inputs to the Alameda
and Contra Costa countywide and subregional models to assure consistency among the models.
Approach and Methodology
Pursuant to the passage of Proposition 111,Alameda and Contra Costa Counties will develop congestion
management programs which require that the Tri-Valley model be consistent with MTC's modeling
methodology and assumptions. Also,a methodology that incorporates both the Alameda and Contra Costa
models will need to be developed. It is anticipated that this will involve writing a program that
incorporates Contra Costa trip generation models and data for the zones in Contra Costa County and the
Alameda trip generation model and land use for zones within Alameda County. The modeling
methodology will be reviewed with MTC staff for approval
Product
The product of this task will be a technical report documenting the model that will be used in the Tri-
Valley area. This report shall be sent to the MTC for their review and approval. To-ensure that the
consistency standard is met, the CONSULTANT shall meet with the MTC to answer any questions they
may have.
Task 2: Network/Zone System Definition
Purpose
The CONSULTANT shall design the focused zonal system and the detailed highway and transit networks
for the Tri-Valley area model Network definition shall include proper location of traffic zone"centroid"
connector links and other network details. CONSULTANT shall review the location and number of traffic
zones and centroid connectors with each locality and incorporate comments.
Approach and Methodology
Traffic Zone System: Definition of the zonal.system to be used for the Tri-Valley model will be the
responsibility of the CONSULTANT. Using AAA base maps, the CONSULTANT shall prepare a
Cooperative Agreement No. 45.01.00 Exhibit A
Between Contra Costa Transportation Authority and Page 2 of 13
County of Alameda, Pleasanton, Dublin, and Livermore
preliminary draft and a draft version of a refined zone structure for Tri-Valley that will be submitted to
the jurisdictions, the counties, and the Contra Costa Transportation Authority for review. Based upon the
jurisdictions' comments, a final zone map will be prepared and distributed to the jurisdictions, the
counties,and the Authority. The refined zone system will consist of subsets of the individual county-level
structures, the 1980 census tracts, and MTC's 550-zone system. To the extent possible,zone boundaries .
shall correspond with city jurisdictional limits. The remaining portions of Contra Costa and Alameda
Counties shall be consistent with MTC's 550-zone system. In the other Bay Area counties,the aggregated
zone size shall correspond with the MTC superdistricts.
Highway Network.CONSULTANT shall refine the highway network to provide a suitable level of detail.
The networks shall include freeways, major and minor arterials, and selected collector streets. The
CONSULTANT shall assure that all FAU (Federal Aid Urban) routes will,be included in the network.
Using AAA base map, the CONSULTANT shall prepare preliminary draft and draft roadway, maps
showing the proposed street system to be included in the network, including critical roadway
characteristics, such as number of lanes, facility type (freeways, arterials, collectors), and area type (i.e.,
CBD, residential, rural). These maps will be sent to each of the jurisdictions for review. Based on their
comments, the network definition will be finalized.
Transit Networks:The CONSULTANT shall review and update the transit networks previously developed
for the countywide models_ The networks will be reviewed by transit operators against current service
practices and shall be updated by the CONSULTANT ' as required.
End Product
The end product of this task will be a reproducible map showing the refined zone system, and roadway
maps displaying the roadway facilities to be coded in. the network, including the critical roadway
characteristics, such as facility type and number of lanes.
Task 3: Update Demographic Data Base
Purpose
CONSULTANT shall develop the land use and demographic data for the base year(1990) and two future
years (2000 and 2010) necessary to do the model validation and produce the travel forecasts.
Cooperative Agreement No. 45.01.00 Exhibit A
Between Contra Costa Transportation Authority and Page 3 of 13
County of Alameda, Pleasanton, Dublin, and Livermore
Approach and Me[hodology
The travel demand model requires land use and demographic data input at the appropriate zone level for
all nine Bay Area counties. For the purpose of land use data collection, the nine Bay Area counties will
be divided into the following regional areas:
Region 1. Tri-Valley area
Region 2. The remainder of Contra.Costa County
Region 3. The remainder of Alameda County
Region 4. Other seven Bay Area counties
Region 5. San Joaquin County.
The data.inputs for the zones within Regions 1, 2, and 3 consist of the following variables:
1. Number of Households
2. Household Population
3. Employed Residents
4. Household Income (expressed in 1979 or.1980 $)
5. Retail Employment
6. Service Employment
7. Other Employment
8. Total Zonal Acres
9. Diablo Valley And Contra Costa College Enrollment
10. Alameda County Model data requirements.
For the areas external to Regions 1,2,and 3,only the total number of jobs and households for each traffic
zone will be prepared. The zonal structure in areas outside Regions 1,2,and 3 are at a greatly aggregated
level that shall only require household and employment variable in order to produce travel forecasts.
Economic and Planning Systems (EPS), as a subconsultant to Barton-Aschman, with participation of
Alameda County and Contra Costa County staff and the Tri-Valley jurisdictions,shall create the data base
system containing detailed existing and future land use assumptions for all the traffic zones within Contra
Costa County and the Alameda County portion of the Tri-Valley area for the years 1990,2000,and 2010.
With this data base system, land use and demographic data files for Regions 1 and 2 will be created to
be used as the input for the trip generation model
EPS contribution to the land use and demographic input refinement will consist of the following effort:
• Improvement/modification of the existing computer data base system.
EPS shall use data base management programs used for the Contra Costa County
General Plan as the building block for this application. Modifications shall be
Cooperative Agreement No. 45.01.00 Exhibit A
Between Contra Costa Transportation Authority and Page 4 of 13
County of Alameda, Pleasanton, Dublin, and Livermore
made to reflect the refined zone system. New data gathered from the participating
jurisdictions shall be added to the data base. EPS will provide system support to
the cities on an as-needed basis.
• Data Collection and Research.
EPS with assistance of Alameda County and Contra Costa County staff and the
participating Cities of San Ramon, Livermore, Dublin, Pleasanton and the town
of Danville, shall prepare the 1990, 2000, and 2010 land use and demographic
data. EPS shall provide the cities with data specifications and the data formats
and shall provide overall guidance to the participating jurisdictions in the data
collection effort. The 2010 land use projection, prepared by EPS, will be
constructed using rend line analysis from. ABAG projections, other available
projections, market data, and land capacity analysis.
• Documentation.
EPS shall prepare documentation describing the data sources, estimated
relationships and other assumptions used in the development of the 1990, 2000,
and*2010 land use data basis. EPS will prepare comparison spreadsheets showing
the existing (1990) and future (2000 and 2010) land use and demographic
assumptions by zone and jurisdiction. These assumptions will be submitted to the
jurisdictions and MTC for review and comments.
Years 1990,2000,and 2010 household and employment data for areas external to Regions 1,2 and 3 shall
be constructed by the CONSULTANT based upon available data from the Alameda Countywide
Transportation Plan,from the Association of Bay Area Governments(ABAG)projections,available MTC
data, and external travel data from Caltrans: If necessary, year 2010 household and employment
projections shall be adjusted in order to obtain an acceptable job/housing ratio in the region.
End Product
The end product of this task will be computer data files containing the land use and demographic variables
for each traffic zone within Contra Costa County and the Alameda County portion of the Tri-Valley area,
as well as for the zones representing the remainder of the Bay Area counties for 1990, 2000 and 2010.

County of Alameda, Pleasanton, Dublin, and Livermore
Task 4: Network Coding
Purpose
CONSULTANT shall code the highway and transit networks based on the roadway and transit definitions
from Task 2.
Approach and Methodology
The Alameda and Contra Costa County highway networks shall be used as the basis for the network
development in Tri-Valley. Beyond freeways and major and selected minor arterials, which are currently
present within the counties'networks,the complete set of minor arterials and selected collectors as defined
in Task 2 shall be added to the highway network CONSULTANT shall refine the network in the areas
surrounding Tri-Valley, in order to better reflect travel patterns between Tri-Valley and outlying areas.
The peak-hour and off-peak period.transit networks, obtained from the existing alameda Countywide
network, shall be updated and implemented in the model. The contra Costa County network shall be
incorporated into this network.
End Product
t'he end product of this task will be a base year(1990) highway and transit network, including centroid
connector locations, representing a detailed transportation system in and immediately bordering the Tri-
Valley area.
Task 5: Traffic Data Requirements
Purpose
The purpose of this task is to obtain current year(1990) traffic count data for use in validating the Tri-
Valley subarea travel demand models.
Approach and Methodology
Mainline traffic counts on freeways,expressways,and arterials should be provided for an average weekday
as well as for both the AM and PM peak hours. Intersection count data should include AM and PM peak-
Cooperative Agreement No. 45.01.00 Exhibit A
Between Contra Costa Transportation Authority and Page 6 of 13
County of Alameda, Pleasanton, Dublin, and Livermore
hour turning movements at major arterials, including on- and off-ramps. The CONSULTANT shall
request existing roadway and intersection traffic counts from Caltrans and from each jurisdiction. The
CONSULTANT shall review and compile this count data and prepare a list of proposed locations where
additional counts will be necessary. Following review by the jurisdictions, each individual jurisdiction
will conduct additional traffic counts as required.
Daily transit ridership information(for BART,BART Express, County Connection.and LAVTA) will be
collected by the CONSULTANT.
End Product
The end product of this task will be a set of current roadway traffic counts and intersection turning-
movement counts for use in validating the Tri-Valley travel demand model. The count locations and dates
shall be illustrated on a map of the area.
Task 6: Model Implementation
Purpose
The purpose of this task is to get the model up and running by implementing the travel demand model
within the EMMF,/2 transportation planning software.
Approach and Methodology
This task involves updating the model application procedures to reflect the revised zonal structure. The
same travel demand model structure as for either of the countywide models shall be used in order to
ensure consistency with the countywide travel demand models. The 1990 land use and demographic data
files, developed in Task 3, shall be used as input for the selected trip generation program. The
mathematical equations representing the trip distribution, modal choice.models, and the assignment
procedure, shall be updated in the EMMFE12 software. User friendly macros shall be created to allow
application of the various modeling procedures in sequence without.manual intervention.
End Product .
The end product of this effort will be an executable travel demand forecasting model for the Tri-Valley
area that will be validated in Task 8.
Cooperative Agreement No. 45.01.00 Exhibit A
Between Contra Costa Transportation Authority and Page 7 of 13
County of Alameda, Pleasanton, Dublin, and Livermore .
Task 7: Traffic Engineering Programs
Purpose
The focus of this task is to develop the data base files that are used by computer programs to convert
E QYfE,R output to a format readable by traffic engineering level of service programs.These files are also
used in the validation effort to compare counted intersection turning movements with model-forecasted
turning movements.
Approach and Methodology
The CONSULTANT shall create a turning-movement file and a geographic correspondence file for each
counted intersection. These files shall be used to automate the validation effort by creating a comparison
table of counted and EMME/2-simulated turning movements for these intersections.
The CONSULTANT will develop separate computer programs to take data from EMIVIFF,/2 output adjusted
based on existing count data, which will be combined with descriptions of intersection geometrics(such
as the number of lanes for each movement, signal phasing, etc.) to perform intersection level of service
calculations for various level of service programs, such as the V/C program. The V/C program will
include the Furness adjustment procedure for intersection analysis.
,;The CONSULTANT shall perform AM and PM peak-hour level of service calculations at 80 to 85 major
intersections in the Tri-Valley area. These intersections include all ramp terminals and most major arterial
intersections within the study area. The level of service analysis will be performed for the 1990, 2000
and 2010 traffic conditions. The CONSULTANT,in conjunction with the jurisdictions, will provide the
1990 (existing) AM and PM peak-hour turning-movement counts at the selected intersections as well as

Task 8: Model Validation
Purpose
The purpose of this task is to adjust the model so that the travel demand modeling system produces
realistic, validated estimates of current traffic-flow patterns in the Tri-Valley area.
Approach and Methodology
The CONSULTANT shall execute the trip generation, trip distribution, modal split, and trip assignment
modules for the 1990 base year and measure the accuracy of the model against actual traffic volumes.
The CONSULTANT shall validate the model to the following tolerances, by jurisdiction, for ADT, and
peak-hour directional traffic or levels mutually agreed upon by the Authority, the Counties and
jurisdictions-
Seventy-five percent of freeway link volumes will be within +/- 20 percent.
Fifty percent of freeway link volumes will be within+/- 10 percent.
Seventy-five percent of major arterial link volumes will be within+/- 30 percemr
Fifty percent of major arterial link volumes will be within +/- 15.percent
Intersection movements greater than.1,000 vehicles per hour-- 50 percent will be within
+/-20 percent
Intersection movements between 500 and 1,000 vehicles per hour— 30 percent will';;-
within +/- 20 percent
These tolerances are based on direct output from Emmet and do not include any manual adjustments.
Higher tolerances will be achieved by manually adjusting the model output and developing, where
appropriate, factors to bring the model generated numbers closer to the counts.
Intersection taming movements will be estimated based on using the Femess adjustment method as
described in the Authority's Technical Procedure Manual. The intersection analysis will be conducted
using adjusted volumes.
The CONSULTANT shall prepare detailed comparisons of observed and estimated average daily(and AM
and PM peak-hour) traffic volumes at critical roadway sections and screenlines, as well as peak-hour
turning-movement volumes at intersections in the Tri-Valley area to test the models' accuracy. Based on
the,results, adjustments shall be made in the modeling process, and new model runs shall be performed

until the model output reasonably agrees with observed traffic flows. If necessary for validation, the need
for special generators shall be analyzed.
CONSULTANT shall analyze transit ridership projections, make comparisons with the data collected in
Task 4, and adjust the model to validate transit-passenger levels.
End Product
The end product of this task will be a validated Tri-Valley travel area forecasting model . The
CONSULTANT shall provide plots and appropriate tabulations for review by the jurisdictions.
Task 9: Travel Forecasts
Purpose
The purpose of this task is to produce year 2000 and year 2010 forecasts for the Tri-Valley area.
Approach and Methodoloo
The CONSULTANT will meet with staff from the Tri-Valley cities,the Authority,the counties, Caltrans,
and transit agencies(BART and LAVTA),to obtain transportation plans that are likely to be implemented
by 2000 and 2010. CONSULTANT shall submit the plan improvements to Alameda County and the
Authority for their review and approval for inclusion into the future networks. CONSULTANT shall code
plan improvements into the model to develop 2000 and 2010 highway and transit network alternatives for
the Tri-Valley area.
The corresponding land use and demographic data for 2000 and 2010 developed in Task 3 shall be input
into the model to project future travel.
The CONSULTANT shall run the model to produce the 2000 and 2010 forecasts. CONSULTANT shall
check the reasonableness of the forecasts by comparing screenline and link-level data with existing traffic
and validated 1990 model output. CONSULTANT shall analyze the following model outputs:
• AM and PM peak-hour and average daily traffic volumes on freeways and
arterials.
• AM and PM peak-hour turning movements and level of service projections at
selected intersections.

County of Alameda, Pleasanton, Dublin, and Livermore
• AM and daily transit ridership on BART, County Connection and LAVTA.
CONSULTANT shall adjust the model to obtain forecasts that appear reasonable when compared with
existing data and future employment and population data
End Product
The product of this task will be a technical memorandum describing the approach, methodology,
assumptions, and results of the year 2000 and year 2010 travel demand.forecasts.
Task 10: Documentation
Purpose
The purpose of this task is to prepare appropriate documentation of the travel demand model, and
prepare a user instructions manual for correct application of the focused Tri-Valley Model.
Approach and Methodology►
CONSULTANT shall prepare a Technical Report documenting the approach, methodology, assumption
and results of the Tri-Valley Model. The report shall include existing count data and validation records
in a technical appendix:
The Technical Report shall describe the development and validation of the travel demand model. The
report shall document the networklzone and land use
generation/distribution/assignment methodologies for the Tri-Valley model step-by-step.
pll �e trip
CONSULTANT shall prepare a Users' Guide to provide instructions for running the Tri-Valley Model.
Included in the Guide shall be computer-program-flow diagrams and the options and parameters used
when executing the travel models as well as the utilization of separate programs that will convert model
output to a suitable format for.subsequent traffic engineering applications.
End Product
The end product of this task will be a Technical Report and a Users' Guide for the Tri-Valley Model.
Upon completion of the Tri-Valley Travel Demand model, the CONSULTANT shall deliver all the
'hardware and software to the location designated by the Authority in conjunction with Alameda Counties
and the Tri-Valley jurisdictions.

Task 11: Meetings and Project Administration
Purpose
The purpose of this task is to provide a regular basis for coordination of activities to anticipate any scope
or schedule changes and to document progress and performance throughout the agreement period. The
task also includes coordination meetings with the MTC, Caltrans.and local jurisdictions.
Approach
Trend meetings will be held on a monthly or"as-necessary" basis with representatives of the Tri-Valley
Transportation Council,the Authority, and Contra Costa and Alameda County staffs,to review the status
of the project. The existing budget will allow for eight trend meetings. .For each trend meeting, the
CONSULTANT shall prepare the following items:
• Agenda: The agenda should address technical issues,scopelbudget issues,€ rjte-
week horizon schedule, Master Schedule, and percent-complete versus perm*;el"
expended_
• Four-Week Horizon Schedule: Shows key current activities and those l lanncd
during the next month Key activities that span beyond the month may be shown
using dates.
• Action Items Log: Key submittals and issues for involved parties should be
shown on the Action Items Log. If responses are expected, the initial due datc
should be shown and the final date monitored.The log should give a continuous
chronology of the project from start to finish. However, only the most recent
action items need to be attached to the agenda.
• Master Schedule: Shows key project activities through the completion date,with
emphasis on deliverables, review periods by jurisdictions/committees, and final
submittals at the end of the contract duration. Master schedule should be date-
specific and easily updatable, as activities may be added or deleted.
