- Phase 3: System Implementation
- Phase 4: Construction Inspection Assistance
- Phase 5: System Acceptance Testing
- Phase 6: Documentation and As-Built Plans
- Phase 7: Staff Training
- Phase 8: Before and After Study System Evaluation
- Phase 9: Start-up and On-Going System Maintenance
The list below describes the five major system
improvement components of this PROJECT. Pursuant to this
Agreement, the CONSULTANT shall complete Phase 1 for each of
these components.
1. Advanced Traffic Management System (ATMS)
This component consists of the development,
design, selection, and implementation of a complete
interjurisdictional ATMS. The ATMS will include the hardware
and software necessary to allow monitoring, controlling, and
coordinating the operation of traffic signals and, in the
future, other Intelligent Transportation Systems (ITS) field
devices along Telegraph Road. The system will be operated from
individual agency work stations which will have traffic
surveillance capabilities through detecting and monitoring
signal status, traffic congestion and incidents, and will
display this information through a fully integrated mapping
function. The system will also be able to detect equipment
malfunctions which will enable the operator to initiate
appropriate maintenance operation responses and various other
responses to traffic events and congestion either manually or
automatically using an expert system application.
It is anticipated that the system will provide
once-per-second monitoring of traffic signals,
interjurisdictional communication with localized control, and
levels of security to restrict access to unauthorized users.
The system will also employ strategies such as
interjurisdictional data sharing, cooperative efforts in
timing plan development, a coordinated response to arterial
incidents, congestion and special events, and traffic data
analysis. Additionally, the system will provide local and
regional level access, controls, and connections to the future
I?105 Corridor Traffic Management Center (TMC), and other
future regional traffic forum TMCs, the City of Los Angeles'
ATSAC System, Los Angeles County TMC, and Caltrans Districts 7
and 12 TMCs.
As part of this component, each municipality
will be provided with work stations capable of controlling its
jurisdiction's traffic signals, as well as the ability to
monitor all signals along the I-5/Telegraph Road Corridor from
its remote work station site. Also, provisions shall be made
to allow an individual city to control other jurisdiction's
signals full time or during nonpeak hours and weekends. These
control strategies will be accomplished by the execution of
multijurisdictional agreements. Typically, a work station will
consist of a computer system located at each jurisdiction's
city hall or other location and will be fully capable of
satisfying that jurisdiction's traffic management needs, as
well as the requirements of the PROJECT. This component will
provide the hardware and software necessary to provide these
capabilities to each I-5/Telegraph Road Corridor Agency.
For all jurisdictions in the Corridor with
existing traffic control systems, an analysis will be
completed to determine the need for replacement or
modification of their respective systems. In the event that
the PROJECT recommends, and the city desires to maintain its
system, then the ATMS will provide an interface and any
required equipment to enable communication and insure
compatibility with the other jurisdictions in the Corridor. In
this instance, the ATMS will be a hybrid system which will
consist of a combination of new and existing systems.
Another element of the ATMS is the establishment
of a comprehensive Vehicle Detection System for the Corridor
to supplement the existing traffic signal detectors and to
collect real-time traffic data and information at key
intersection locations where monitoring of traffic is critical
to the movement of vehicles. The amount, type, and location of
system detectors will be determined by the CONSULTANT after
careful consideration of the user needs, system functional
requirements, and available budget.
Although an Advanced Traveler Information System
(ATIS), Closed Circuit Television (CCTV) cameras, Changeable
Message Signs (CMS), and other ITS elements are not part of
this PROJECT, the ATMS must be capable of accommodating the
installation of these elements in the future, and be able to
provide the necessary control, map display, and monitoring
functionality.
The development of this ATMS will require a
traffic management system operations plan which will identify
the existing and the desired level of operation, and recommend
the most suitable ATMS to fit those needs. The CONSULTANT will
be required to select and implement a Commercial Off-the-Shelf
(COTS), or other previously developed, advanced traffic
management system software capable of interfacing with the
Countywide Architecture currently under design by Los Angeles
County.
As part of the overall Gateway Cities Forum
Project, DPW is working on Traffic Signal Synchronization
Program (TSSP) improvements on Telegraph Road. The work
includes intersection and signal controller upgrades, signal
timing, and a proposed installation of a new signal at the I-5
northbound off-ramp on Telegraph Road. Since the
implementation of the ATMS being developed in this PROJECT
will also involve signal controller upgrades, the CONSULTANT
will be required to coordinate with DPW staff on controller
upgrade requirements.
2. Local City Control Site
This component will include a schematic floor
plan, facility specification, staffing, training and
operations and maintenance requirements of a typical local
city control site. Additionally, the CONSULTANT will identify
a preliminary site for each city's control site proposed to be
installed by the PROJECT by conducting an on-site inspection
and make recommendations on necessary alterations to this work
space to provide the needed functionality. In future phases,
it is anticipated the CONSULTANT will install the control
sites for the affected agencies.
3. System Integration
This component will integrate all of the
PROJECT'S components to ensure an open system architecture is
maintained and all PROJECT components are integrated in a
seamless environment with a common interface. The ATMS must
have the ability to interface with all related ITS elements
implemented through other projects such as other regional
traffic forum projects, other city systems, Caltrans systems,
and all Southern California ITS Priority Corridor Steering
Committee projects, such as the Showcase Project. The local
city control sites must also be integrated with future
subregional TMC(s) in the Gateway Cities Forum, Los Angeles
County, and Caltrans Districts 7 and 12. The system must also
be integrated and compatible with the Countywide Architecture
currently under development by DPW's consultant under the San
Gabriel Valley Signal Operation and Maintenance (SOM) Pilot
Project. The CONSULTANT shall also consider future integration
with other potential stakeholders and users mentioned
above.
The CONSULTANT shall also develop user interface
requirements in order to interface to and coordinate with the
above projects. The CONSULTANT shall generate top-level data
flow diagrams for each Graphic User Interface (GUI) and review
the interface prototype with the users. A standardized and
user-friendly interface will also be developed by the
CONSULTANT as part of this component to facilitate system
expansion, operation, maintenance, and training. The
CONSULTANT will provide all developer tools and detailed
instructions to enable agency staff to modify the user
interfaces to reflect future expansion and changes in the
system, e.g., addition of signals, cameras, desired changes to
database layouts, etc., after PROJECT completion.
4. Communication System
This component includes the design of a
communication system capable of supporting the recommended
inter-jurisdictional ATMS design. The installation of a
communications network is essential to support the traffic
signal operation, monitoring, and control capabilities of the
ATMS, as well as information exchange with other
jurisdictions, stakeholders, and systems. These may include
the State of California Department of Transportation
(Caltrans) Freeway Management System, Los Angeles County
arterial traffic control system, and other existing and
planned systems outside the Gateway Cities area. In designing
the system, the CONSULTANT must research and take advantage of
opportunities to reuse existing or planned communications
facilities.
This communication network must include links
between the field infrastructure units (such as the system
detectors and controllers) and each jurisdiction's traffic
control site. Additionally, it must include communication
links between each local city site and any regional or
sub-regional control site, such as the Gateway Cities I-105
Corridor TMC and the County of Los Angeles TMC.
Since the communication system will drive the
capability of all system components, both present and future
ITS elements must be considered in the design. Additional
primary considerations must be the expandability to include
other potential stakeholders and users, system expansion to
include additional signals, and the cost effectiveness of the
system. Possible communications medium technology may include,
but not be limited to, twisted pair cable, leased telephone
lines, fiber optic cables, spread spectrum radio, very small
aperture terminals, or a combination of the above.
Any recommendations made by the CONSULTANT for
this PROJECT shall be for the implementation of "open systems"
and shall be made after careful review of potentially suitable
systems for use in the Gateway Cities Forum. This includes
completed systems or systems currently under development in
other traffic forums. The recommendations made shall occur in
close coordination with the Intermodal and Jurisdictional
Integrated Network Environment (IMAJINE) Project, any
applicable Southern California Priority Corridor ITS Steering
Committee Projects, Los Angeles/Ventura County ITS
Coordinating Committee Projects, and Regional Traffic Forum
Projects, throughout Los Angeles County to ensure a seamless
environment with a common interface. The CONSULTANT shall
build on previous work undertaken by these projects and
committees and, where applicable, use completed work products
to avoid unnecessary work or duplication of effort in this
PROJECT.
The CONSULTANT shall perform the tasks and
subtasks for Phase 1 pertaining to the five major traffic
signal system improvement components of the PROJECT and
provide deliverables as described herein.
For each deliverable outlined in this Agreement,
the CONSULTANT shall submit to the COUNTY draft versions for
review and comment. If the first draft is acceptable to the
COUNTY, COUNTY will distribute copies to all affected agencies
for review and comment prior to being returned to CONSULTANT
for preparation of final documents. If the first draft
submitted to COUNTY is not acceptable to the COUNTY, it will
be returned to CONSULTANT until it is in a form acceptable for
distribution to the affected cities.
The CONSULTANT is required to address all agency
comments. Any agency comment which will not be incorporated
into a report shall be discussed, either verbally or in
writing, with the COUNTY and the writer of the comment.
A draft deliverable shall be considered accepted
by COUNTY and CONSULTANT may invoice COUNTY for the cost of
the deliverable when COUNTY determines, in its sole
discretion, that the draft deliverable is acceptable for
distribution to the affected cities. A final deliverable shall
be deemed accepted by the COUNTY and CONSULTANT may invoice
the COUNTY for the cost of the deliverable upon receipt by
CONSULTANT of a written notification of acceptance from the
COUNTY.
The CONSULTANT shall use the standard DPW
software set forth below when preparing deliverables. The
CONSULTANT shall provide deliverables in bound hard copies and
in a file format (on diskette[s]) or via E-Mail) importable to
the standard DPW software. Current DPW standard software is as
follows.

Processing
- LOTUS 1-2-3 or Microsoft Excel -
Spreadsheet
- Microsoft Project - Project Management
and Project Plan
Exhibit B (Schedule of Deliverables and Payment
Schedule) of this Agreement provides the payment schedule for
each deliverable included in this Statement of Work. Payment
shall be made in accordance with the Agreement.
PHASE 1: CONCEPTUAL DESIGN MASTER PLAN
The CONSULTANT shall prepare the Conceptual
Design Report and plans for each PROJECT component. This will
be accomplished by first preparing a detailed and
comprehensive user and system functional requirements
document. Based on this document, the CONSULTANT shall perform
an alternatives analysis to select the best alternative to
satisfy the identified user and functional needs. These
recommendations will culminate in a Conceptual Design Master
Plan document for each PROJECT component which will identify
improvement locations, the type of technology to be used, the
conceptual design and specifications, a detailed description
of the tasks involved with the implementation and installation
of each PROJECT component, and cost estimate. This information
will serve as the foundation for the Detailed Design Phase
(Phase No. 2) and will be used as a starting point for
building consensus on a variety of institutional issues
including cost sharing and possible funding sources for
operating and maintaining the proposed improvements once they
are in place.
The CONSULTANT shall complete the draft or final
version (if a draft version is not to be completed for a
specific task) of all deliverables for the tasks in this phase
within __ months of receipt of the Notice to Proceed for this
PROJECT from the Director.
ATMS
In this task, the CONSULTANT will obtain the
user needs and system functional requirements of the ATMS.
Based on this information, the CONSULTANT will evaluate
various alternative systems and recommend the most suitable
for the PROJECT. In addition, the CONSULTANT will research the
existing Vehicle Detection System , propose upgrades and new
installations as necessary to enable the selected ATMS to
function as efficiently and effectively as possible. In
addition, it is the intention that the system has the
capability to respond to and interface with future
functionality which provides for inter-agency coordination of
operations (e.g in response to incidents and special
events)
Local City Control Site
The CONSULTANT shall provide the Conceptual
Design documents for the physical accommodations which will be
necessary for the design and implementation of the local city
control sites. CONSULTANT shall also identify any additional
hardware and software necessary for local control site
operations not included in other tasks. Primarily, this shall
involve the Conceptual Design of the following.
� The equipment, furnishings, and staff
necessary to operate a typical local city control site;
and
� Any other component, such as additional hardware and
software required to bring the local control sites to full
operation.
This task will include the Conceptual Design of
a typical local city control site. This Conceptual Design will
include a schematic floor plan, and control site facility
specifications identifying required building and system
operational, functional, staffing, training, and O&M
requirements. Additionally, the CONSULTANT will be responsible
for identifying preliminary locations for each local city
control site by conducting on site inspections. The CONSULTANT
shall also identify those proposed agency control site
locations requiring physical alterations to meet the typical
control site design characteristics.
Communications
In the initial stage of the PROJECT, the
CONSULTANT will conduct an analysis of the user needs and
functional requirements of the communications system. Based on
this analysis, the CONSULTANT will evaluate several
alternative communication modes and recommend the most
suitable for the I-5/Telegraph Road Corridor.
System Integration
The CONSULTANT shall prepare a Conceptual Design
for integrating the I-5/ Telegraph Road transportation system
components in a seamless environment with a common interface
by ensuring that an open system architecture is maintained.
Since the work to be performed under this task deals primarily
with the operational issues resident in the integration
process of the I?5/Telegraph Road Corridor, technical systems
integration conceptual design shall be performed by the
CONSULTANT in conjunction with the Conceptual Design of the
four transportation system components of this PROJECT.
Another primary component of this task is the
integration with other existing systems within the Gateway
Cities area such as those under development under Project
IMAJINE and the I-105 Project. Integration with other systems
throughout Los Angeles County is also anticipated. These
systems include, but should not be limited to, the City of Los
Angeles' Automated Traffic Control System, the Southern
California Priority Corridor Showcase Project, and other
systems currently under development in other forum areas. This
task will define the system interface and integration
requirements for these systems. The Conceptual Design of a
standardized and user friendly interface will also be
completed by the CONSULTANT as part of this task to facilitate
system maintenance and training.
