THIS AGREEMENT, entered into as of this day of
19 , by and between `
i
and (herein called the City) , WITNESSTH THAT:
WHEREAS the City desires to engage the Contractor to render certain
!
technical or professional services hereafter described in connection with an under-
taking which is expected to be partially financed under the Governor's Office of
Traffic Safety. �
s
NOW, THEREFORE, the parties hereto do mutually agree to as follows:
1. Employment of Contractor. The City hereby agrees to engage the I
i
Contractor, and the Contractor hereby agrees to perform personally the services
hereinafter set forth in connection with the Project of the City under the Texas
Traffic Safety Program.
f
2. Area Covered. The Contractor shall perform all the necessary services
provided under this Contract the covering all areas within the city limits, herein
i
call the "study area." r
3. General . This proposal is submitted to the City as a study with the
purpose to develop workable solutions to existing and potential traffic and pedestrian
problems as they exist near and on the roadway and to prepare recommended standards
and policies to follow in evaluating the future traffic problems. Traffic engineering
improvements related to the proposed bond improvement shall be clearly presented with
1
in the scope of the study. �
Widespread changes in highway and street traffic signs and pavement markings
I
during the next few years will effect every American motorist and pedestrian. With
the recent adoption of anew Texas Manual on Uniform Traffic Control Devices, states
I
and local communities have a target date of 1977 to implement these pavement marking
i
requirements, 1977 for signs, and 1980 for signals. This schedule will set a format
i
I
to be followed in development of new workable traffic control programs in Baytown
ram^ along with the development of standard procedures to be enacted.
The use of modern traffic engineering principles and a uniform standard
for traffic control will reduce the frequency and severity of traffic accidents. This
study will provide the unified work program for Baytown to accomplish the safe and
efficient movement of vehicles and pedestrians in a professional manner using traffic
engineering principles.
A documented report will be prepared based on the findings and recommenda-
tions with cost estimates for an implementation program.
Scope of Services. The Contractor shall do, perform, and carry out per-
sonally, in a satisfactory and proper manner, as determined by the City, the following:
PART A Compile all existing available data on traffic counts, land use, traffic
generation, and parking from previous studies covering Baytown. The consolidation
and review of the existing data will eliminate the duplication of previous analysis
of traffic problems in Baytown. It will also allow the compilation of all previous
studies into one operational plan for traffic engineering and safety. Some of the
existing studies and data to be reviewed and utilized are as follows:
(1) Baytown Comprehensive Report, Benard Johnson, Inc. , 1965.
(2) Decker Drive Traffic Study by Traffic Engineers, Inc. , 1972.
(3) Traffic Volume Studies by City Planning Department.
(4) Various urban transportation studies by the Texas Highway Department.
(5) Volume studies and counts by the Texas Highway Department and the City.
Y
l_ PART B Analysis of traffic volumes.
The collection of traffic volumes will afford the opportunity to evaluate
relative priorities of numerous traffic problems in Baytown. The volume counts will
provide a means to document warrants for existing traffic control devices or remove
existing traffic control devices no longer needed. Excess use of control devices
causes loss of respect by the motorist for the device and, therefore it can become
and unsafe control creating unnecessary delays to everyone.
1 Develop a traffic volume flow ma based on existing volume data and the
( ) p p 9
use of yearly projections. These volumes would be used for the evalu-
ation of the capacity of the major arterial streets and also for the
development of priority ratings for projects. The same streets used
in the 1964 flow map will be included in the updating.
(2) Traffic volume counts will be made at each signalized intersection.
These traffic counts will be conducted manually. Each of these, counts
will be analyzed for determination of the proper type of traffic
control device.
' (3) Develop a standard traffic volume count program for use by the City
as a continuing program. This would include a standardization of forms
for 24-hour counts or continuous hourly counts as well as the develop-
ment of periodic flow maps.
(4) Develop a volume count reference map to show cordon count points, key
station points, and other miscellaneous volume count locations. This
' map should become the reference map to be used for the continuing
planning program relating the traffic volume increases.
r
PART C. Inventory and analysis of traffic signal system. The efficient flow of
traffic and pedestrians upon city streets is very dependent upon the performance of
the traffic signal control operation. Since this is a large expenditure of City funds,
and planned for the proposed bond improvement program, careful evaluation and planning
is very important in this area. Baytown must implement improvements for updating their
traffic signals to be in accordance with the Manual on Uniform Traffic Control Devices
by 1980. It will be the object of this study to present a workable plan for Baytown
to be in compliance with the set standards. This will provide for the safety of
pedestrians at high density locations.
The Contractor proposes to accomplish the following:
(1) Inventory each existing traffic signal location and develop the
following:
(a) intersection sketch or condition diagram;
(b) controller type, model , and date of installation;
(c) signal phasing, cycle length, f 9 P 9� Y g offset and split information;
i
(d) number of signal faces for each approach, type of mountings, and
size of lens.
(e) type of pedestrian control and indications.
rq (2) Development of a city-wide map showing the location of and types of
all signals and interconnected systems.
(3) Evaluate the efficiency of each location and the overall system and
OWN point out recommended changes and cost estimates. This shall include
time space diagrams for any system recommended as determined by desired
flow patterns measured on the arterial street. All railroad pre-
emption devices shall be presented in accordance to the Manual on
Uniform Traffic Control Devices.
1?
(4) Develop an overall plan for a traffic signal system based on future
j
traffic volumes, development plans and roadway designs.
i
(5) Develop a layout for each intersection warranted in accordance with I
the Manual on Uniform Traffic Control Devices. The
layout shall be
developed for the bond program implementation and to include type of
control , location and type of mountings, (mast arm or span wire) and
conduit routing. The layouts shall be developed to be usedfor
future engineering plan developments for a construction program.
(6) Develop recommended standard procedures for the investigation of a
request for the installation of a trafficT signal . his shall be in
accordance with the Manual on Uniform Traffic Control Devices, and set
a procedure to be followed by the City.
. (7) Develop typical installation standards such as mountings and number
of signals.
(8) Assign priorities for the modernization of the traffic signal g system
in order for the City to be in compliance with the Manual by the year
1980. This shall include cost estimates for immediate improvements
and ultimate design.
PART D. Inventory and analysis of regulatory and warning traffic signs and pave-
ment markings. Safety combined with effective control and movement is accomplished
through good signing and pavement markings so the motorist and pedestrian will under-
stand the circulation desired.
Since the adoption of the symbolic code for traffic control signs, it is of
utmost importance that Baytown quickly provide a full change-over program to these
new standards. This will provide a reduction in the accident experience on the City
streets as well as provide a clear precise meaning of the symbol sign. Recently
stop and yield signs have been updated in Baytown.
In order to achieve maximum response from the motorist, the Contractor
proposes to accomplish the following:
(1) Inventory of each street in Baytown to develop the following:
(a) Sign type and location for all regulatory and warning signs
(b) Pavement markings - color and type.
(c) Developj procedures for standardization of installation of signs
and markings.
(d) Review existing school signing and pavement marking procedures
and develop recommendations for any changes.
(e) Evaluate signs as to their conformance to the MUTCD.
(f) Develop necessary replacement procedures and schedules.
PART E. Accident study and analysis. From an engineering standpoint, the evalu-
ation of accident patterns on the streets provides a means to correct deficiences
that would go unrecognized without this surveillance. To pinpoint street deficiencies
in design and operation, the analysis of the accident experience at critical locations
is -proposed to be evaluated as follows:
(1) Develop collision diagrams for the twenty (20) intersections with the
highest number of collisions during a continuous twelve (12) month
period. A complete three (3) year program of accident evaluation shall
be conducted at these locations.
t
(2) Develop a field condition 'diagram at each of these twenty (20)
intersections.
(3) Develop recommendations for immediate action and future improvements
to be made that will relieve an accident prone location
I 4) Develop a city-wide inventory of all pedestrian-motor vehicle accidents
during a continuous twelve (12) month period identifying the location
and times of all such accidents. Establish procedures for improving '
the protection of pedestrians.
PART _F. Capacity analysis. The maximum use of a street is determined by comparing
the existing volumes with the capacity of the street. If a deficiency exist,
�1
additional capacity must be developed.
The capacity of the street determines when additional safety through
construction or other means must be undertaken. The capacity calculation provides the
relative severity of the problem and will be used to provide relative priorities for
the implementation phases. j
i
The Contractor proposes to accomplish the following:
(1) Determine the existing capacity of each signalized intersection based
on acceptable procedures recognized by -the Institue of Traffic
Engineers.
(2) Where existing volumes are available, compare the capacity figures
for the determination of capacity deficient intersections.
(3) Develop recommendations to alleviate the capacity deficient inter-
sections through geometric changes, signal changes, etc.
PART G. Street circulation study. Determination of the most effective street
system is set by the ability of the motorist to easily and safely use the street.
Congestion and unsafe conditions exist many times because the way the
! street is actually used is inadequate for the articular
P land use adjacent to the
„w, street. For instance, a one-way street reduces the number of vehicular conflicts
from 44 to 11 and thereby provides less potential for an accident to happen. This
phase of the study will carefully evaluate all possible improvements that can be
spotted to eliminate as many potential accident situations as possible.
To make sure this exists, the Contractor proposes to do the following:
(1) As a minimum evaluate existing traffic circulation on each arterial
street.
(2) Conduct travel time speed and delay studies on the following arterial
streets during the peak periods and off peak periods:
(a) S.H.146 from Spur U5 to Cedar Bayou
(b) Decker Drive - Bayway Dr. to traffic circle
(c) Texas Ave. - traffic circle to Tri-City Beach Rd.
(d) Main Ave. - Baker Rd. to Market
(e) Sterling - Decker Dr. to S.H.146
1
r
(f) Bayway - Decker Dr. to Wisconsin
(g) Defee - Decker Dr. to S.H.146
(3) Study street circulation throughout the City and develop recom-
mendations regarding recommended changes. Evaluate the problems
where school children and pedestrian crossings are at a hindrance with
vehicular traffic. Evaluate the need for possible overpasses for the
separation of pedestrians and vehicles.
(4) A travel time contour map shall be developed using major arterial
streets as a base flow.
The central business district has developed plans for a semi-mall type
development that will change parking parallel to angle and the existing 4 travel lanes
will be reduced to 2 low speed lanes. The diversion of traffic shall be evaluated
and any improvements shall be presented through schematic presentations.
PART H. School safety is a highly emotional subject in each City. There are many
areas of responsibility by different agencies when it involves school safety. Recog-
nizing the problem and the new problem of daylight savings time during the winter, `
this stud will observe and define potentially dangerous situations and propose policy
Y P Y 9 P P P Y
and designs for the safety of the school children from an outside unbiased view
point.
The school traffic safety study will include the following:
(1) Map of all schools in City with any zoning or boundary restrictions.
(2) Signing and pavement marking around schools.
(3) Inventory existing sidewalks adjacent to schools.
(4) Establish safe school routes to elementary schools" (13) following
meetings with each school administrator.
(5) Develop recommendations relating to improved safety around schools.
6 Evaluate each school during darkness hours for problem i( ) va uate e c s ool ng p em situations.
!l
I
• I�
PART I. Existing ordinances. A review of the existing traffic ordinances that have
INN ;f
been utilized for a number of years should be updated to modern technology and
operation. Recommendations for the administration's responsibilities in traffic
engineering, both legal and operations, should be made.
PART J. Development of report with data and recommendations. The complete
documentation of the study would include the summary of data obtained and based on
the analysis, recommendations would be set forth to the City for the systematic
i
approach toward eliminating existing and future traffic movement and safety problems. �
r
The report would set forth standards and procedures for the City to follow that would !
s
be in accordance with the accepted traffic engineering practices. It would include
recommended priorities for each area of improvement and cost estimates for planning
such improvements. Where the ideal improvement recommended appears to cost more than
I
the City could reasonably be expected to afford, less costly alternatives will be
I
identified with cost and effectiveness estimates provided.

Contractor, and the Contractor hereby agrees to perform personally 'the services
hereinafter set forth in connection with the Project of the City under the Texas
Traffic Safety Program.,
2. Area Covered. The Contractor shall perform all the necessary services
provided under this Contract the covering all areas within the city limits, herein
call the "study area." .
3. General . This proposal is submitted to the City as a study with the
purpose to develop workable solutions to existing and potential traffic and pedestrian
problems as they exist near and on the roadway and to prepare recommended standards
and policies to follow in evaluating the future traffic problems. Traffic engineering
improvements related to the proposed bond improvement shall be clearly presented with-
in the scope of the study.
Widespread changes in highway and street traffic signs and pavement"markings
during the next few years will effect every American motorist and pedestrian. With
the recent adoption of a new Texas Manual on Uniform Traffic Control Devices, states
and local communities have a target date of 1977 to implement these pavement marking

efficient movement of vehicles and pedestrians in a professional onal manner using 'traffic
P 9
engineering principles,
A documented report will be prepared based on the findings and recommenda-
tions with cost estimates for an implementation program,
Scope of Services. The Contractor shall do, perform, and carry out per-
sonally,ly, in a satisfactory and proper manner, as determined by the City, the following:
PART A Compile all existing available data on traffic counts land use traffic
generation, and parking from previous studies covering Baytown, The consolidation
and review of the existing data will eliminate the d •
upl�cation of previous analysis
of traffic problems in Baytown, It will also allow the compilation 1 ati on of all previous
P P
studies into one operational plan for traffic engineering Y and safety. Some of the
existing studies and data to be reviewed and utilized are as follows:
(1) Baytown Comprehensive Reports Benard
Johnson, Inc., 1965,
(2) Decker Drive Traffic Study by Traffic Engineers,neers� Inc. , 1972,
g
(3) Traffic Volume Studies by City P1 an"i ng Department.
De .
t
Various urban transportation studies b •
y the Texas Highway Department, ,
(5) Volume studies and counts by the Texas
Highway Department and the City.
ty.
PART B Analysis of traffic volumes.
The collection of traffic volumes will afford the opportunity to evaluate
PP Y
relative priorities of numerous traffic problems i n •
. P Baytown. The volume counts will
provide a means to document warrants for existing traffic control devices or remove
existing traffic control devices no longer needed. Excess use of control devices
causes loss of respect by the motorist for the device andt therefore it can become
4
and unsafe control creating unnecessary delays to everyone,
(1) Develop a traffic volume flow map based on existing -volume data and the
use of yearly projections. These volumes would be used for the eval u-
ati on of the capacity of the major arterial streets and also for the
development of priority ratings for projects. The same streets used
in the 1964 flow map will be included in the updating.
(2) Traffic volume counts will be made at each signalized intersection.
These traffic counts will be conducted manually. Each of these, counts
will be analyzed for determination of the proper type of traffic
r
control device.
(3) Develop a standard traffic volume count program for use by the City
as a continuing program. This would include a standardization of forms
for 24-hour counts or continuous hourly counts as well as the develop-
It
ment of periodic flow maps.
(4) Develop a volume count reference map to show cordon count points, key
station points, and other miscellaneous volume count locations. This
map should become the reference map to be used for the continuing
planning program relating the traffic volume increases.
PART C. Inventory and analysis of traffic signal system. The efficient flow of
traffic and. pedestrians upon city streets is very dependent upon the performance of
the traffic signal control operation. Since this is a large expenditure of City funds,
and planned for the proposed bond improvement program, careful evaluation and planning
i s very important in this area. Baytown must implement improvements for updati ng' thei r
. y P
traffic signals to be in accordance with the Manual on Uni form .Traffic Control Devices
by 1980. It will be the object of-this study to present a workable plan for Baytown
to be in compliance with the set standards. This will. provide de for the safety of
pedestrians at high density locations.
The Contractor proposes to accomplish the following:
(1) Inventory each existing traffic signal location and develop the
following: .
(a) intersection sketch or condition diagram;
(b) controller type, model , and date of installation;
W signal phasing, cycle length, offset and split information;
(d) number of signal faces for each approach, type of mountings, and
size of lens,
(e) type of pedestrian control and indications.
(2) Development of a city-wide map s howi rig the location of and types of
all signals and interconnected systems,
(3) Evaluate the efficiency of each location and the overall system and
point out recommended changes and cost estimates. This shall include
time space diagrams for any system recommended as determined by desired
flow patterns measured on the arterial street. All railroad pre-
emption devices shall be presented in accordance to the Manual on
Uniform Traffic Control Devices.
(4) Develop an overall plan for a traffiq signal system based on future
traffic volumes, development plans and roadway designs.
(5) ..Develop. a layout for each intersection warranted i n.-accordance_ with
the Manual on Uniform Traffic Control Devices. The layout shall be
developed for the bond program implementation and to include type of
control , location and type of mountings, (mast arm or span wire) and
conduit- routing. The layouts shall be developed to be used for
future engineering plan developments for a construction program.
1
(6)* Develop recommended standard procedures for the investigation of a
request for the installation of a traffic signal . This shall be in
accordance with the Manual on Uni form'Traff i c Control Devices, and set
a procedure to be followed by the City.
(7) Develop typical installation standards such as mountings and number
of signals,
(8) Assign priorities for the modernization of the traffic signal s system
in order for the City to be in compliance with the Manual by the year
1980. This shall include cost estimates for immediate improvements
and ultimate design,
PART D. Inventory and analysis of regulatory and warning traffic signs and pave-
ment markings. Safety combined with effective control and movement is accomplished
through good signing and pavement markings so the motorist and pedestrian will under-
stand the circulation desired.
Since the adoption of the symbolic code for traffic control signs, it is of
utmost importance that Baytown quickly provide a full change-over program to these
new standards. This will provide a reduction in the accident experience on the City
streets as well as provide a clear precise meaning of the symbol sign. Recently
stop and yield signs have been updated in Baytown,
In order to achieve maximum response from the motorist, the Contractor
proposes- to accomplish- the following:
(1) Inventory of each street in Baytown to develop the following.
(a) Sign type and location for all regulatory and warning signs
(b) Pavement markings - color and type,
(c) Develop procedures for standardization of installation of signs
and markings.
(d) Review existing school signing and pavement marking procedures
and develop recommendations for any changes.
(e) Evaluate signs as to their conformance to the MUTCD.
(f) Develop necessary replacement procedures and schedules.
PART E. Accident study and analysis. From an engineering standpoint, the evalu-
ation of accident patterns on the streets provides a means to correct deficiences
that would go unrecognized without this surveillance. To pinpoint street deficiencies
in design and operation, she analysis of the accident experience at critical locations
is proposed to be evaluated as follows:
(1) Develop collision diagrams for the twenty (20) intersections with the
highest number of collisions during a continuous twelve (12) month
period. A complete three (3) year program of accident evaluation shall
be conducted at these locations.
(2) Develop a field condition diagram at each of these twenty (20)
intersections.
(3) Develop recommendations for immediate action and future improvements
to be made that will relieve an accident prone location.
(4) Develop a city-wide inventory of all pedestrian-motor vehicle accidents
during a continuous twelve (12) month period identifying the location
and times of all such accidents. Establish procedures for improving
the protection of pedestrians.
PAS Capacity analysis. The maximum use of a street is determined by comparing
the existing volumes with the capacity of the street. If a deficiency exist,
additional capacity must be developed.
The capacity of the street determines when additional safety through
construction or other means must be undertaken. The capacity calculation provides the
relative severity of the problem and will be used to provide relative priorities for
the implementation phases.
The Contractor proposes to accomplish the following: .
(1) Determine the existing capacity of each signalized intersection based
on acceptable procedures recognized by..the Insti tue of Traffic
Engineers.
(2) Where existing volumes are available, compare the capacity t figures
P P Y 9
for the determination of capacity deficient intersections.
(3) Develop recommendations to alleviate the capacity deficient inter-
.
sections through geometric changes, signal changes, etc.
PART G. Street circulation study. Determination of the most effective street
system is set by the ability of the motorist to easily and safely use the street.
Congestion and unsafe conditions exist many times because the way the
street is actually used is inadequate for the particular land use adjacent to the
street.* For instance, a one-way street reduces the number of vehicular conflicts
from 44 to 11 and thereby provides less potential for an accident to happen. This
phase of the study will carefully evaluate all possible improvements that can be
qO
spotted to eliminate as many potential accident situations as possible.
To make sure this exists, the Contractor proposes to do the following:
(1) As a minimum evaluate existing traffic circulation on each arterial
street.
(2) Conduct travel time speed and delay studies on the following arterial

(3) Study street circulation throughout the City and develop recom-
mendations regarding recommended changes. Evaluate the problems
where school children and pedestrian crossings are at a hindrance with
vehicular traffic. Evaluate the need for possible overpasses for the
separation of pedestrians and vehicles,
(4) A travel time contour map shall be developed using major arterial
streets as a base flow.
The central business district has developed plans for a semi-mall type
development that will change parking parallel to angle and the existing 4 travel lanes
will be reduced to 2 low speed lanes. The diversion of traffic shall be evaluated
and any improvements shall be presented through schematic presentations.
PART-He School safety is a highly emotional subject in each City. There are many
areas of responsibility by different agencies when it involves school safety. Recog-
ni zi ng the problem and the new problem of daylight savings time during the winter,
this study will observe and define potentially dangerous situations and propose policy
and designs for the safety of the school children from an outside unbiased view
point.
The school traffic safety study will include the following:
- (1) Map of -all schools in -City with any zoning or boundary restrictions.(2) Signing and pavement marking around schools,
(3) Inventory existing sidewalks adjacent to schools.
(4) Establish safe school routes to elementary schools- (13) following
meetings with each school administrator.
(5) Develop recommendations relating to improved safety around schools.
(6) Evaluate each school during darkness hours for problem situations.

PART In. Existing ordinances, A review of the existing traffic ordinances that have
been utilized for a number of years should be updated to modern technology and
operation. Recommendations for the administration's responsibilities in traffic
engineering, both legal and operations, should be made.
PART J. Development of report with data and recommendations. The complete
documentation of the study would include the summary of data obtained and based on
the analysis, recommendations would be set forth to the City for the systematic
approach toward eliminating existing and future traffic movement and safety problems,
The report would set forth standards and procedures for the City to follow that would
be in accordance with the accepted traffic engineering practices. It would include
recommended priorities for each area of improvement and cost estimates for planning
such improvements. Where the ideal improvement recommended appears to cost more than
the City could reasonably be expected to afford, less costly alternatives will be
identified with cost and effectiveness estimates provided.
