Generic Traveler
Management Coordination Center Concept of Operations
[D]
Prepared for:
US DOT
Prepared by:
SAIC
January 12, 2006
Background
The Mobility Services for All Americans initiative is one of the U.S.
Department of Transportation's Intelligent Transportation Systems (ITS)
Program's Tier I initiatives. The goal of the MSAA initiative is to
provide enhanced mobility and accessibility to all Americans through
the use of technology integration, service coordination, and the efficient
use of resources.
The foundation of the Mobility Services for All Americans (MSAA) initiative
is built around the notions of service coordination and technology
integration. Currently, delivery of human services transportation is
challenging due to a plethora of issues such as inefficiencies, limited
resources, and lack of coordination. In many locations, human services
transportation is fragmented, resulting in service area gaps (geographical
areas where service is not provided) or limited service area size due
to an absence of trip transfers between transportation providers. Often,
customers must:
- Contact multiple case workers among multiple funding programs.
- Make trip requests well in advance.
- Contend with inconvenient scheduled trip times.
- Deal with long and difficult to estimate pick-up wait times.
- Endure long trip travel times.
- Contend with limited accessibility to transit, especially if the
traveler is a senior or a person with disabilities.
- Overcome difficulties in locating information on the availability
of transit alternatives.
New capabilities and opportunities are being created in both the transportation
and health and human services communities through the use of emerging
technologies and innovative services. Pioneering public transportation
agencies are using Intelligent Transportation Systems (ITS) to provide
centralized coordination of community transportation providers, one-stop
shopping, and service brokering through integrated automatic vehicle
location systems, advanced communications, and universal benefit cards.
Others are providing on-vehicle audio annunciation, accessible traveler
information, and flexible routing to assist passengers with disabilities
in using conventional transit services. In the rehabilitation community,
innovative Assistive Technologies (AT) such as personal GPS and personal
digital assistants (PDA) using mobile communications provide real-time
assistance to those with cognitive disabilities, while accessible pedestrian
signals and "talking" bus stops and signs are also being developed.
However, the two communities are often unaware of the research, new
approaches, and advances that each is making, and neither may have
direct communication with the disability community at large.
The U.S. Department of Transportation (USDOT) is helping to bring
these communities together through MSAA in an effort create a coordinated
approach to the application of technological solutions to the barriers
to accessibility and mobility for all Americans. Ultimately, MSAA seeks
to:
Establish replicable and scalable models of traveler management
coordination centers [TMCC], that provides one-stop, unified customer-based
travel information and trip planning services, and supports coordinated
human services transportation operations.1
It is hoped that the combination of many available technologies brought
together in a TMCC can help overcome the barriers and gaps facing all
travelers. The purpose of this generic concept of operations is to
help local stakeholders to successfully plan and design this type of
TMCC. Technical and planning challenges, if not overcome prior to and
during implementation, can affect how useful the technology will be.
This document is also meant to create a preliminary picture of the
ideal TMCC that could best meet the transportation needs of all Americans.
The concept of operations document has been kept generic - that is,
a notional deployment scenario has been described throughout the document.
In the foundational research undertaken to support the MSAA effort,
many stakeholders cautioned that one model may not work well in all
applications. Therefore, this document should support the implementation
of different configurations of a TMCC.
Definition of A Generic TMCC Concept of Operations
This generic concept of operations for a TMCC is a document that provides
a user-oriented vision of the system that can be understood by stakeholders
with a broad range of operational and technical experience. This concept
provides a method of identifying institutional, operational, and technical
aspects of traveler management coordination. The purpose of this document
is to provide both guidance in completing a detailed, specific concept
of operations for a TMCC and examples to help writers 2 understand
the type of material that should be included. A "generic system" has
been described throughout the concept. This is meant to illustrate
how a stakeholder would develop a concept of operations and, ultimately,
the deployment of a TMCC.
This document communicates the overall needs that the TMCC should
satisfy and provides the basis for development of an individual, site-specific
TMCC concept of operations. An individual concept of operations for
a TMCC:
- Ensures that all users and supporters have the same understanding
of the TMCC. By providing a description of the components and operations,
stakeholder misunderstandings can be reduced and expectations can
be managed.
- Clearly defines conditions for the use of the TMCC. This should
minimize the risks associated with operating a TMCC. A concept of
operations should include non-technical descriptions of all TMCC
users, the data and information that they need to operate and use
the TMCC, and the conditions under which they use this data and information.
- Documents the operational needs of the users without defining
specific technical issues.
- Provides the operational needs and proposed characteristics for
the proposed TMCC.
- Describes high-level user expectations and functional requirements
for the TMCC.
- Describes information sharing across programs and operators.
Figure 1 provides a graphical depiction of the high-level elements
of a generic concept of operations.
[D]
Figure 1. Textual Representation of the Major Elements of a Typical
Concept of Operations3
Using The Generic Concept Of Operations
The final TMCC concept of operations document will be a guideline
for the implementation of the TMCC. It will identify connections and
attributes of the proposed TMCC, and the interfacing entities and systems.
The generic concept of operations presents illustrative examples of
operational scenarios for various applications of the TMCC. Each scenario
describes, in narrative text, illustrated cases. Sequence diagrams
may eventually support the description of each scenario. Stakeholders
may use these examples as they consider what scenarios they would like
to include in their final TMCC concept of operations.
The TMCC generic concept of operations should include all stakeholders,
existing ITS, proposed ITS, and transportation modes that will be affected
by the operation of the new TMCC. The generic concept of operations
is designed to be used by the primary stakeholders who will use the
description of a generic TMCC as a model to complete a more specific
concept of operations document. The stakeholders' specific concept
of operations document should detail the specific conditions, modes,
and needs that will be incorporated into the deployed TMCC.
Again, the remainder of the document will use examples from a "generic
system" to illustrate particular points in the MSAA concept of operations.
The generic system is described below in detail.
Generic System Description
The goal of the generic system, as with the MSAA initiative, is to
develop a replicable, scalable TMCC which will enhance service accessibility
and operational efficiency and provide a single point of access to
customer-based travel information and trip planning services for all
Americans, especially persons with disabilities, older adults, and
individuals with lower income.
The generic system is intended to be a representative example of a
real-world TMCC and may not include every possible component/subcomponent
of a TMCC as outlined in SAIC's Mobility Services for All Americans
Phase 2 Foundation Research Final Report.4 Furthermore,
not every component or subcomponent is required (nor perhaps even desirable)
for a successful TMCC. The decision as to which components to include
will depend upon the needs, resources, and goals of the communities
or agencies actually undertaking such implementations. While the generic
system could be either a physical or virtual system (and will include
actual tangible resources, such as computers and dedicated staff) for
purposes of the generic system that is described the remainder of this
document, the TMCC is a virtual system with dedicated staff members.
The generic system includes some type of communication network among
all relevant funding agencies, contract and/or agency operators, service
providers, and the general public. This communications network is the
primary means by which the users (riders) schedule a trip. While this
network should be technology-based and use telephone and Internet resources
to support it, it should also utilize person-to-person interfaces as
additional or back-up means of communication for the users/riders.
This will help troubleshoot any problems encountered as users try to
schedules rides and trips. It is important to note that this communications
network may use different forms between stakeholders; for example,
communication between a funding agency and an operator might take on
one form, but the communication between a customer (e.g., user or rider)
and a provider may take on another form.
The generic system benefits from a local champion who ensures the
successful implementation and operation of the TMCC. The system also
utilizes stakeholder involvement throughout its life-cycle: all stakeholders
have been involved in the planning design, procurement, deployment,
and evaluation of the generic system. The generic system's stakeholders
include:
- USDOT.
- State DOT.
- Other State agencies administering and/or funding human service
transportation programs.
- Local transit agencies.
- Contract operators that provide service for the transit or human
service agency.
- Privately-provided human service transportation services.
- Users/customers.
- Private sector representatives, such as ITS vendor(s).
Memoranda of understanding (MOU), agreements, and shared policies
with agencies delineate service, administration, funding, and management
roles and responsibilities among providers and other stakeholders.
These agreements address the following topics:
- Cost sharing.
- Shared eligibility processes between programs.
- Shared service (e.g., vehicles, reservations, etc.).
- Shared billing/reporting.
- Shared or linked technology (e.g., database, scheduling, dispatching,
reporting, billing).
- Shared information across programs and operators.
The generic system's operations include fixed route transit, demand response
services, flexible services (e.g., point-deviation, route-deviation,
service routes, or community bus routes,5 and
volunteer driver programs). It uses a single point of access that provides
customer-based travel information, trip planning services, and access
to travel training services. The generic system includes multiple funding
agencies, service providers, and operators, including: local and State
transit agencies, health and human service agencies, department of labor
agencies, department of education, family service agencies, and non-profit
and for-profit transportation agencies. The generic system includes five
providers/operators and five different funding agencies, and is scalable.
The generic system benefits from a thorough, efficient, and innovative
design processes:
- The overall process follows a systems engineering analysis approach.
- The design also considers human factors during the planning, design,
implementation and full deployment of the system.
- The generic system keeps successful elements of previous service
offerings. For example, the system accounts for the benefits resulting
from integration with personalization offered by smaller, sometimes
stove-piped, services.
- The system's design incorporates a well-established Coordination
Transportation Plan (e.g., State Action Plan), a product of the United
We Ride campaign. Likewise, it also operates in accordance with the
Regional ITS architecture.
The generic system embarks on both a major promotional campaign highlighting
the potential benefits of the TMCC to stakeholders and users as well
as an ongoing public- relations campaign to promote services to travelers.
The system offers trip (itinerary) planning for customers via the Internet
or telephone, enhancing customer service by providing the customer
with the most cost-effective trip plan while minimizing travel time.
The system offers its travelers the following benefits and features:
- Monthly transit passes.
- Shared rides between passengers from different programs.
- Lower fares for riders who pre-group themselves.
- Fare reduction for off-peak travel.
- Seamless use of multiple modes (e.g., volunteer, demand response,
feeder service, fixed-route transit, etc).
- Discounts for certain modes/cost sharing for certain modes/times.
- Accessible vehicles.
- Easy to understand signage, maps, schedules, etc.
- Information available in multiple languages, formats and via multiple
media.
- Single point of access to call center for reservations and scheduling
(regardless of destination, mode of travel, or provider or payer).
- Customer service center (via phone, email, Internet or in person)
to log concerns, ask questions, buy passes, obtain schedules, make
recommendations, etc.
To summarize, the generic system has the following programs in place:
- Coordinated eligibility processes.
- Single PAYER System from service providers and riders' perspective.
- Integrated operational information system potential measures.
- A central call center "single point of access."
- Education and training (staff, operators, and customers)
- Local/regional contribution/ investment; this investment could
be financial or operational.
- Joint purchase, use and maintenance of vehicles, including fuel,
insurance, etc.
- Intermodal transfer centers.
Generic System Core Elements
The generic system's core functional elements are presented in the
logical order in which they would be deployed, as follows:
- System backbone, which consists of:
- A database which acts as a repository to support business
processes. Includes information on funding, eligibility requirements,
fare structures, customer information, etc.
- A data dictionary, which allows data/information exchange
among systems and sub-systems, and ultimately between and among
funding agencies' and transit provider(s') systems.
- Elements which support travel planning, including:
- A booking system (e.g., reservations) that allows access
through a variety of means, including 211/511, web, etc. However,
must contain at least some options for human interface
- A scheduling and dispatching system that optimizes resource
utilization and minimizes customer wait and travel time.
- A fare payment and management system, including:
- An eligibility subsystem that automatically determines
eligibility requirements and supports or denies service
requests.
- A fare collection and payment subsystem that automatically
deducts the fare based on passenger eligibility for program
subsidies.
- Elements which improve operations and customer service, including:
- A tracking/communication system, including:
- A transfer connection protection (TCP) subsystem that
minimizes traveler disruption at transfer points and
facilities.
- A vehicle (asset) visibility subsystem that supports
both scheduling activities, and the provision of real-time
arrival and progress information to travelers.
- A safety and security subsystem that provides facility,
vehicle and passenger security and safety via systems
such as on-board cameras and recording, collision detection,
silent alarms (panic buttons), facility cameras and recording,
and automated activation of information and lights.
- Elements which support simplified financial transactions, accounting
and program management, including reporting, reimbursing, smart card
fare collection, payment, recharging, etc. These elements should
be transparent to the users.
- A traveler information system that provides information to riders
before they make their trip, once trips are scheduled and en route
(as trips are being taken).
- System activities which occur after service is provided, such as:
- An invoicing subsystem, which automatically allocates costs
across programs based on agreed-to formulae and/or actual trip
elements, develops invoicing reports, and minimizes preparation
time and errors.
Additionally, the generic system uses key human and technical resources,
such as manned help desks (to help riders find and access service)
and smart card technology (to facilitate payment).
Major stakeholders of the generic system include:
- Customer: Rather than interfacing with individual
agencies, the customer now interfaces with a central entity. This
is similar to what is being proposed in the Oregon State-Wide Trip
Planner discussed in Chapter 3 of the Mobility Services for All Americans
Phase 2 Foundation Research Final Report. Interaction can occur through
standard phone, 511, or 211 to human or IVR, Internet, web-enabled
(Wireless Access Protocol) cell phone, PDA, etc. Previous ITS evaluations
have shown that, in addition to any automated system, users should
be provided the option of reaching a human attendant. Subsequent
to booking and scheduling a trip, the customer can utilize the TMCC
to make changes to their planned itinerary and/or to receive real-time
arrival information.
- Transportation Providers: Under this model, transportation
providers are able to focus solely on operations. Interaction with
other providers, funding agencies, and customer bookings occur through
the TMCC. Passenger pick-ups, routing decisions, and scheduling are
processed by the TMCC and provided to the transportation providers
in real-time. Providers continue to monitor their vehicles (where
capable) and seamlessly provide this information back to the TMCC.
Eligibility decisions are made by the TMCC and invoices are automatically
produced.
- Funding Agencies: Funding agencies interact solely
with the TMCC. Agencies provide standards for invoicing, which are
updated as necessary. Centralized invoices are produced by the TMCC
and submitted to the appropriate funding agencies.

Concept of Operations
The following sections detail the areas which should be covered by
the specific concept of operations. To provide sufficient detail to
the authors of future concept of operations documents, some sections
provide examples as they would be found within the "generic system."
I. Scope
This section includes, in addition to the points listed below, diagrams
to describe relationships and processes. Figures 2 and 3 from the earlier
description of the Generic TMCC provide high-level examples of system
schematics. The scope contains sufficient information to serve as the
Executive Summary of the document.
a. Document contents.
b. Who is the audience of the concept of operations? These
are the agencies that will deploy, operate, and use the TMCC. For example,
they are usually part of the following organizations:
- USDOT.
- State DOT.
- Other State agencies administering human service transportation
programs.
- Local transit agencies who are participating in the TMCC deployment.
- Privately-provided human service transportation services which
are involved in or affected by the model deployment.
- Site-specific deployment expertise (e.g., consultants who will
assist in the development of a specific concept of operations document).
- Technology vendors.
c. Identify stakeholders. Stakeholders are identified
according to the needs and requirements of each deployment site. In
many cases, they are the same entities who will be using (i.e., creating
or referencing) the concept of operations. In addition to the concept
of operations audience, all users of the transportation system should
be considered deployment stakeholders. For the purpose of this generic
concept of operations, four stakeholder groups have been identified:
- Primary stakeholders:
- State agencies administering and/or funding human service
transportation programs.
- Local transit agencies.
- Contract operators that provide service for the transit
or human service agency.
- Privately-provided human service transportation services.
- Secondary stakeholders:
- Other interest groups:
- Site-specific deployment expertise (e.g., consulting firms).
- Technology vendors.
- Users/customers - riders, single point of access call centers.
d. Define system boundaries - identify the:
- Entities included in the system. These entities:
- Are within the primary organization that is developing or
will operate the TMCC. For example, it would include state
DOTs, human service agencies, and local level transit agencies
- whether public or community/non-profit. In the Generic System,
these entities are local and state transit agencies, health
and human service agencies, department of labor agencies, department
of education, family service agencies, and non-profit and for-profit
transportation agencies.
- Play a significant role in system design, deployment and/or
operation. For example, USDOT, technology vendors, and other
private companies who may be involved, such as systems integrators,
consultants or evaluators. In the design of the generic system,
technology vendors and consultants were retained to assist
in the planning, design and deployment of the system.
- Are significantly affected by changes in system design and
function. For example, funding agencies, other local providers
(private and/or public/community transit agencies) who are
not deploying the TMCC, but will be impacted by its operation.
The generic system includes five providers/ operators and five
different funding agencies, and is expandable.
- Entities that will be an external interface to the system. These
entities:
- Interact with the system but are outside the scope of its
operation, such as MPOs and other local entities. During the
planning process of the generic system, the stakeholders conducted
a series of meetings with the local MPO and other interest
groups who would be utilizing the systems functionality to
assess their needs and requirements.
- Play a secondary role in system function or are only affected
by system function.
- This section should also define where the TMCC's coverage
will end. For example, will the system operate across multiple
jurisdictions? If so, these additional jurisdictions should
be defined and discussed briefly in this section.
e. Purpose for implementing the system:
- Define current needs. From the MSAA Foundation Research, the system
should respond to the following needs:
- Need for service and for that service to be reliable (on-time
arrivals and departures).
- Need to know about that service and how to plan a trip.
- Need for accessibility. For example, the vehicles or vehicle
stop locations are easy for all individuals to physically access.
- Need for flexibility. For example, a customer can easily
make changes to their trip (e.g., route and point deviation).
- Security. Security is important to all Americans; nearly
all travelers are seeking safe and secure travel options. At
times, it may be the most important factor in someone's trip.
- Identify current shortcomings. This section generally describes
the current state of the practice in high-level, generic terms. From
the MSAA Foundation Research, the system must attempt to mitigate
the following gaps and barriers:
- Areas of no service.
- Areas of limited service or service times.
- Absent and/or limited service information.
- Absent service assistance (to answer questions and help
users understand how to use the system).
- Limited trip flexibility; for example, the trip must be
booked many hours or even days in advance.
- Limited service accessibility.
- Variable service reliability.
- Difficulties in taking chained or multi-destination trips.
- Inefficiencies in vehicle routing, scheduling, and tracking.
- Lack of standardized reporting requirements among funding
agencies.
- Lack of automation in recordkeeping.
- Institutional issues: these could vary to include items
such as:
- Financing for technology procurement, implementation,
and on-going operations and maintenance.
- Coordinating with other providers and agencies in order
to jointly procure systems and/or exchange data and information.
- Lacking ITS technical experience - this can relate
to either human or computer resources.
- Procuring technology from vendors who are unfamiliar
or inexperienced with human service agency operations
and transportation services.
- Technical concerns, such as:
- The automation of functions. In some cases, automation alienates
customers, thus the benefit of technology is not realized.
- A lack of technical guidance and information.
- A lack of ITS infrastructure, especially in rural areas.
During the generic system planning stage, stakeholders conducted a
formal needs analysis, in which they identified the needs and shortcomings
of their current system. The stakeholders also identified technology
concerns such as the automation of functions, the lack of technical
guidance and information, and the lack of ITS infrastructure. This
step is critical, as it documents important aspects that the potential
TMCC must address. The concept of operations may generally be high-level,
and serve as a starting point for the discussion that takes place at
the needs analysis meetings.
f. Define the overarching vision of the system. With
respect to the generic system, the replicable and scalable TMCC will
enhance service accessibility and operational efficiency and provide
a single point of access to customer-based travel information and trip
planning services for all Americans especially persons with disabilities,
older adults and individuals with lower income. These goals tie in
with the USDOT's Intelligent Transportation Systems (ITS) Joint Program
Office (JPO) and FTA MSAA goals.
g. Define major goals and objectives of the system.
This section describes the goal of each TMCC sub-system. Then a short
description of how replicability and scalability can be achieved in
each subsystem or environment is included. A logical means of presenting
the sub-systems is in the order in which they would need to be deployed.
For example:
- First-level systems. These must exist before any other systems
are implemented. These would likely include:
- Data dictionary.
- Database.
- Second-level systems. These include elements that are required
to plan travel; i.e., make reservations, schedule vehicles and drivers,
and dispatch vehicles. They include:
- Booking.
- Scheduling and dispatching.
- Fare payment and management:
- Eligibility.
- Fare collection and payment.
- Third-level systems: these are systems that involve providing service
to the customers, including:
- Tracking:
- Transfer connection protection.
- Asset visibility.
- Security and safety.
- Fourth-level systems, which provide information to travelers once
the trips are scheduled and service is being provided. For example,
traveler information.
- Fifth-level systems - these are provided after service is used.
For example, invoicing.
- Potential environments: could include any combination of elements.
Some examples include:
- Areas:
- Rural / "remote frontier."
- Urban.
- Small urban.
- Suburban.
- Operation:
- Fixed route.
- Demand response.
- Flexible (e.g., route- or point-deviation).

III. TMCC System Overview
This section describes what the TMCC will do: the how and when of
its activities and functions.
a. High-level diagram(s) of the TMCC. This section
presents the depictions of the TMCC configurations. In the generic
system, these high-level diagrams were presented in figure 2 and figure
3. System designers may also choose to present specific schematics
for each subsystem. The diagrams present the configuration and interaction
of these subsystems, whether it is a physical configuration, a virtual
configuration with the presence of centralized hardware and data base
support, or a virtual configuration without the presence of centralized
hardware and database support.
These diagrams are meant to show the relationship of the TMCC to each
of the subsystem and transportation system elements. The final diagram(s)
and configuration of the TMCC should ultimately be completed by the
primary stakeholders and local implementation team. The diagram(s)
may serve as the basis for any operational scenario diagrams presented
in the "Operational Scenarios" section of the concept of operations.
b. Text description of this diagram.
c. Description of high-level system parameters, such
as:
- System scope (geographical boundaries, stakeholders).
- Goals and objective of the TMCC. For example, a goal of the TMCC
is to increase the mobility of all users of the transportation system,
while the objective of the TMCC would be the steps which are taken
to achieve this goal. In this case, the objectives are to expand
the service area, service hours, or staff productivity while remaining
within the existing budget.
- Users (define their relationship to the system).
- System interfaces (internal and external, user relationships,
sub-system relationships).
- System states or modes (operating modes, how relationships with
other sub-systems change with each mode).
- System capabilities (high-level).
- System architecture.
IV. Operational Description of the TMCC
The model deployment site which is selected will affect how this section
of the concept of operations is completed. This section largely defines
high-level functional requirements, operational constraints, and staff
roles and responsibilities. It describes the current operating conditions,
why the TMCC is needed (justification), and the nature of the changes
the TMCC will have on the existing transportation system.
a. Operational overview.
- Describe the current transportation system. For example: modes
(for example, normal, maintenance, training, and emergency) or operations.
- Define existing systems. Reference the list of sample sub-systems
in Part I, g. of this document
- Identify the functional requirements that must be satisfied by
the model deployment.
- Define what subsystems will be added as part of the TMCC model
deployment. Again the list of sample sub-systems acts as a starting
point.
b. Staffing. Define the roles and responsibilities
of staff within each agency that is included in the system. In the
generic system, they are either Primary or Secondary Stakeholders,
Interest Groups, or Users/Customers. Interest Groups and Users/Customers
do not need to be assigned responsibilities, as they are not likely
to be directly involved in the design and deployment of the notional
TMCC.
c. Operational processes (when, in what order, operations
take place).
- Describe the existing system. Specific elements will be dependent
on the model deployment site. The generic system's concept of operations
includes a detailed description of the existing transportation capabilities,
modes, and operations; it should also include a list and short description
of all ITS that are currently in use and all coordination activities
that are taking place.
- Describe the interface(s) among existing and proposed systems.
The generic system's concept of operations describes how the TMCC
elements will fit together. For example, the system may operate via
a central, physical center. It also may operate as a virtual center
with centralized hardware and databases. Finally, it could also operate
virtually with NO centralized hardware or database support. The deploying
agency may develop a unique scheme for how the TMCC will operate
and interface with their existing systems. The diagrams and schematics
may assist in these descriptions.
- Describe the institutional framework and constraints for the existing
transportation system and ITS.
- Describe the system's operation from each user's perspective.
The generic system's concept of operations includes short descriptions
of each stakeholder's role in both the entire transportation system
and in the proposed TMCC operation.
- Describe the steps taken to accomplish each TMCC activity. The
generic system concept of operations lays out sample activities that
should be completed by each staff position as a trip is booked. It
is not necessary to provide specific steps for each staff position,
as this may cause the concept of operations to become too detailed.
The generic system relies on flow charts to effectively communicate
this information.
- Describe the nature of the proposed changes (caused by the deployment
of the TMCC) in the transportation system. The generic system considers
and describes operational, institutional, or technological changes.
V. Relationship of the MSAA TMCC to the National ITS Architecture.
Agencies should use the National ITS architecture diagram as a starting
point for defining the relationship of the TMCC to the National ITS
Architecture. Existing connections (operational, institutional, technological,
and stakeholders) and new connections required by the TMCC are then
realized. While the relationship of the TMCC to the National and regional
ITS architecture will ultimately need to be explored by the deployment
site, it does not necessarily have to be completed within the creation
of the concept of operations. This section merely reminds the stakeholders
that these relationships will need to be considered at some point during
the deployment process.
VI. Operational Needs
This section defines the policies and issues that need to be addressed
by stakeholders involved in the TMCC deployment. This will help to
ensure that the TMCC complements and improves the operations of the
existing transportation system. The generic system's operational needs
include:
a. The stakeholders' expected outcomes for the TMCC's operation.
b. The institutional issues addressed by the TMCC.
c. The operational policies that are impacted by the deployment
of the TMCC.
d. The technology considerations that are required (including
both the existing technologies that are impacted - changed or eliminated
- and the technologies that must be added) in deploying the TMCC. This
section could be presented in a various ways. Some examples are:
- "The following current system weaknesses will need to be addressed
by the TMCC..."
- "The (physical/virtual) TMCC concept of operations discusses the
following needs for the system..."
- Tabular: column headings = operational category, needs procedures/practices,
needed policies. The tabular presentation may provide an easy to
reference summary of the operational needs that are satisfied by
the TMCC.
VII. Operational and Support Environment
This chapter includes a description of the required operational support
environments for the individual agency-based systems and the proposed
TMCC. The elements presented in this document are not required - the
arrangement (physical, virtual, etc.) of the TMCC will influence how
this section is presented. This section describes the TMCC in terms
of:
a. Physical facilities.
b. Hardware and software.
c. Staffing.
d. Operational Procedures.
e. Other support necessary to operate the deployed system. For
example:
- Human resources.
- Finance.
- Management.
- Consultant.
- City departments.
- Maintenance.
VIII. Operational Scenarios
This section presents a list of generic scenarios addressed in the
concept of operations. This process begins when the stakeholder group
identifies the basic operating scenarios for the system. The total
number of scenarios described is dependent on the number and type of
stakeholders, unique features of the system (both the entire transportation
system and the TMCC), the transportation services that are provided
by the agency, the transportation system boundaries, and the number
of system states.
a. Scenario Components: The scenario describes the
TMCC operating scheme in general. In the case of the generic system,
the configuration that would be described would be a virtual system
with centralized hardware. It could also be a physical or virtual system
with no centralized hardware, or an alternative deployment method chosen
by the stakeholders to deploy the TMCC.
- Describes the TMCC operation from the perspective of fixed route
service, demand response service, flexible service, human service
agency demand response service, etc.
- Describes the TMCC operation from the trip components a rider
would encounter: planning the trip, accessing the system, entering/using/exiting
the system, and arriving at the trip's destination.
- Describes the system operations for special circumstances. For
example, multi-destination trips, trips which consist of fixed route,
paratransit and/or flexible service elements, trips which cross jurisdictions/agency
boundaries and multi-modal trips.
- Documents the capabilities of each TMCC element or subsystem.
- Describes how each operating scenario appears to the user/customer
groups (i.e., customer perspectives).
- Describes aspects which change along with the operating scenario.
- Describes how the institutional situation and inter-jurisdictional/interagency
interaction adjusts based on the systems operation, if applicable.
- Documents the anticipated impacts or improvements made by the
TMCC during a specific scenarios.
- Documents the disadvantages and limitations of the TMCC during
the specific scenarios.
- Presents alternatives or trade-offs, should there be any available
during that specific scenarios.
b. Scenario 1: Normal operations. The overview of
normal operations should include certain 'unexpected' aspects of normal
operations, such as:
- Normal information request and travel (from trip booking to completion
and post trip back office processing).
- Real-time itinerary change requests.
- Simultaneous scenarios.
- Maintenance activities.
c. Expanded scenarios:
- Changes in service providers/brokers.
- Changes in participating human service programs.

2 An effective concept of operations should
be written by a team. The team should primarily consist of those stakeholders "who
will be at the core of the system, those who will be the immediate users." The
team should be a core group of stakeholders, as opposed to all stakeholders.
This ensures that "the system development focuses on those stakeholders
whose need for the system is most critical." Source: Federal Highway

5 Service routes are one type of flexible
service. The definition of service routes is as follows: Service routes
(also called community bus routes) are "fixed routes that are designed
to reduce the distances that elderly persons and persons with disabilities
must travel to get to and from bus stops. Typically, smaller vehicles
are used, and vehicles travel on neighborhood streets or to mall or hospital
doorways to reduce walking distances. Although routes are designed to
better meet the needs of persons with disabilities and elderly persons,
they are open to the public. Services can be planned as feeders to other
fixed-route services and can include a "route deviation" option." Source:
