Background

Section 1201 of SAFETEA-LU established the Real-Time System
Management Information Program to provide, in all States, the
capability to monitor, in real-time, the traffic and travel conditions
of the major highways of the United States and to share that data with
State and local governments and with the traveling public. On May 4,
2006, the FHWA published a notice in the Federal Register at 71 FR
26399 outlining some proposed preliminary program parameters and seeing
public comments on the proposed description of the Real-Time System
Management Information Program, including its outcome goals definitions
for various program parameters, and the current status of related
activities in the States. We are using the comments we received in
response to that notice to develop regulations on the Real-Time System
Management Information Program. We expect to publish our notice of
proposed rulemaking (NPRM) for this program shortly.
Our forthcoming NPRM does not pertain to subsections 1201(b) and
1201(c)(2). Subsection 1201(b) of SAFETEA-LU requires the FHWA to
``establish'' data exchange formats within 2 years of the enactment of
SAFETEA-LU, or August 10, 2007. Subsection 1201(c)(2) requires that
``States shall incorporate data exchange formats established by the
Secretary under subsection (b) to ensure that the data provided by
highway and transit monitoring systems may be readily exchanged with
State and local governments and may be made available to the traveling
public.''
Further analysis by the FHWA leads to the conclusion that
subsections 1201(a)(1) and 1201(a)(2) do not specifically state that
the use of FHWA-identified data exchange formats is a requirement for
the 1201 programs, but only that the purpose of the section is to meet
the larger goals including sharing data among the State and local
governments and the traveling public. Furthermore, subsection 1201(d)
makes funds eligible to meet the larger goals in 1201(a), but does not
specifically mention that 1201(b) data exchange formats must be used
for an entity to be eligible to apply Federal funds towards
establishing Real-Time System Management Information Programs.
The comments and input received on these questions will not affect
future rulemaking regarding the Real-Time System Management Information
Program as described above. Rather, the comments and input received on
these questions may be used by the FHWA for future guidance development
and/or regulatory changes. We invite the public to submit comments on
this interim guidance. We plan to issue final guidance after we have
evaluated all the comments received on this interim guidance. Comments,
including those from the State DOTs, regarding specific burdens,
impacts, and costs would be most welcome and would aid us in more fully
appreciating the impacts of Data Exchange Formats.

--What guidance would facilitate the application of data exchange
formats in your organization?
--Does the reference document provide adequate detail on the nature of
interoperability to be attained through application of the data
exchange formats?

[[Page 58348]]

--Does your organization make use of the ATIS-01 Broadcast Traveler
Information Market Package defined in the National ITS Architecture?
--What is a reasonable interval between publications of new versions of
the data exchange formats?
--Is there sufficient detail in the ``Functional Area/Requirement
Description?'' If not, how much further requirement description would
be required?
--Many of the requirements map to messages that have optional elements.
Should there be changes to the identification of the optional elements,
which would change the nature of the message as defined by the Standard
Development Organization?
--Does your organization make use of the ITS Standards that are
referenced in the data exchange formats?
--Would independent certification or self-certification be more
effective for validating the application of the data exchange formats?
--Do the data exchange formats relate to the operational practices of
your organization?

The FHWA also welcomes comments and input on the published data
exchange formats that address areas of interest that are not
necessarily addressed in the questions posed above.

Real-Time Information Program: Information Sharing Specifications and
Data Exchange Format Reference Document

Prepared for U.S. Department of Transportation, Federal Highway
Administration (FHWA) & Research and Innovative Technology
Administration (RITA) By National ITS Architecture Team
Version 1.0 Release August, 2007

Background

Section 1201 of SAFTEA-LU establishes the Real-Time System
Management Information Program. The goals of this program are to
improve security of the surface transportation system, address
congestion problems, support improved response to weather events and
surface transportation incidents, and facilitate national and regional
highway traveler information. The desired outcomes are to make Traffic
and Travel Conditions Information available to the traveling public and
to ease the sharing of Traffic and Travel Conditions Information among
public agencies and private enterprise.
The types of information considered for the Real-time Information
Program (RTIP) include but are not limited to
Congestion information,
Traffic incidents that block the roadway,
Roadway weather conditions,
Public transportation service disruptions,
Construction activities affecting travel conditions, and
Travel times on roadway links.
The information needed for RTIP is not necessarily available
everywhere, but the interface will be established with the data that is
available. The RTIP is not concerned with developing the sources of
information but with providing a standard interface to obtain the
information when it does exist. Therefore, the RTIP specifications will
not address data collection. They will focus on center-to-center
exchanges and information that should be made available to travelers.
In addition, these specifications will address information exchanges
only and will not include device control.
There are two efforts described in Section 1201. One is the
establishment of the RTIP in each State per the requirements of Section
1201. This information system is to be created in concert with the
updates of regional ITS architectures as they are maintained. Two is
the establishment of data exchange formats to facilitate the exchange
of information.
These data exchange formats will leverage existing ITS standards to
the greatest extent possible.
This document establishes three components to ease the exchange of
Traffic and Travel Conditions Information:
A Concept of Operations to define the entire RTIP scope,
A set of functional specifications to describe a full
RTIP, based upon the functional specifications set forth in the
National ITS Architecture,
An ITS Standards reference that draws the association
between the RTIP functional specifications and particular ITS
standards.

Concept of Operations

Scope

The RTIP is intended to establish a standard data format to
exchange traffic and travel conditions on major highways among State
and local government systems and the traveling public. The real-time
traffic and travel information to be exchanged with this format
includes
Basic information for managing and operating the surface
transportation system, excluding control
Statewide incident reporting system information
Surface transportation system security information
Congestion information
Weather conditions
Surface transportation incidents
Traveler information
A RTIP may be established in each State to leverage the current and
future capabilities of monitoring the traffic and travel conditions of
the major highways. The data exchange formats will be used for
standardized, interoperable communication among transportation
management systems and the information service providers that collect
that information to disseminate to the traveling public. The
transportation management systems could encompass traffic management,
transit management, maintenance and construction management, and
emergency management organizations.
ITS America's Interoperability Subcommittee adopted the following,
in accord with ISO TC 204, as the definition of interoperability:
``Interoperability is the ability of systems to provide services and to
accept services from other systems and to use the services so exchanged
to enable them to operate effectively together.'' In examining systems
for interoperability, it is useful to distinguish two degrees of
interoperability, ``pair-wise'' and ``end-to-end'' interoperability.
Pair-wise interoperability involves verifying that two systems are able
to exchange data and that the data has the same meaning to each system
and leads to the expected functionality. ``End-to-end''
interoperability involves verifying that the flow and use of data are
consistent from initial input to final outcome. The RTIP is primarily
focused on the ``pair-wise'' interoperability with the specification of
common data formats.
The scope of this program will reach all States. While not all
State or local organizations collect and disseminate the same types of
information, standardized formats will be mapped to the types of
information in use. Standard data exchange formats will aid in the
deployment of standard interfaces among surface transportation systems
and information services. The RTIP is focused on center-to-center
interfaces and the current conditions of the surface transportation
system.
The RTIP is really about implementing interface standards
consistently across the country and facilitating the implementation of
data

[[Page 58349]]

collection and dissemination systems to provide more of the information
needed by the transportation management community and the traveling
public. The standardized common data exchange formats reside above the
traditional 7-Layer ISO OSI communications stack. The OSI layers below
the Application Layer can vary depending on the ITS deployment and will
most likely be Internet (TCP/IP) based.

Current System or Situation

Over the past decade, ITS standards have been developed or are in
the latter stages of development. Traffic management, transit
management, and emergency management systems have been deployed or are
being developed that use different standardized interfaces, different
versions of the standards, or custom (i.e., non-standardized)
interfaces. This leads to potential difficulties in data exchange from
one system to another. Transportation management systems are
increasingly producing congestion-related information but the impact of
that information to address congestion is diminished because of
inefficient data sharing practices.
Transportation system operators need information about incidents,
the current state of the roadway conditions, and events that are
planned in the area of operation. Current conditions or issues in a
neighboring geographic area may affect the local transportation system
in ways both subtle and pronounced. The transit operator needs many of
the same pieces of information to provide the best service to their
riders. Information service providers collect the same kind of
information, integrate, and provide it to the public to aid better
travel decision making.
Information is available everywhere in the surface transportation
system, however, it is not always accessible to transportation system
operators or the traveling public due to the lack of standard
interfaces. The key to unlocking this information is to establish
standard data exchange formats that are implemented consistently in
every State. This would allow a transportation system utilizing the
standard data exchange formats to develop an interface to the outside
world to gather external information and make their own information
available to others who need it without building multiple interfaces
for each external system.

Justification

The RTIP is established in SAFETEA-LU in Section 1201. However, the
justification for this program goes beyond the legislation. The premise
of Intelligent Transportation Systems is to connect the islands of
information in the surface transportation system. Data collected by one
agency's system is often beneficial to a neighboring system or to a
traveler information system. This does not mean that every system has
to be physically connected to all others. Establishing data exchange
formats make data collected by a system available to any organization
that wishes to retrieve it in that same data exchange format.
Establishment of real-time information will not happen all at once.
It needs to be planned by each State and each transportation system in
each State that operates the major highways. Information service
providers may choose to apply these same data exchange formats to
retrieve the information available from the surface transportation
systems, process the information, and send it along to the traveling
public.

Proposed Concept

On May 4, 2006, the FHWA published a notice in the Federal Register
(71 FR 26399) outlining some proposed preliminary program parameters
and seeking public comments on the proposed description of the Real-
time System Management Information Program, including its outcome
goals, definitions for various program parameters, and the current
status of related activities in the States. The proposed concept
described here is based upon the proposed preliminary program
parameters.
The RTIP is built around standard data exchange formats based on
existing ITS standards. The RTIP will establish a reference of data
exchange formats that can be used by State and local agencies as well
as information service providers to build interfaces in their systems
to exchange the real-time traffic and traveler information. An
organization would examine the referenced data exchange formats and
implement an interface to their system that supports the formats.
The system would provide the information it has to this interface,
not a specific system, in the standard data exchange format. No
processing of the information is required, although some manipulation
may occur to make the information item compatible with the data
exchange format. Figure 1 illustrates the concept of the RTIP. The
primary focus of the RTIP is the establishment of data exchange formats
to facilitate the exchange of traffic and travel conditions.

[[Page 58350]]

[GRAPHIC] [TIFF OMITTED] TN15OC07.017

Not all systems will have all the data identified by the data
exchange formats. That is understood and accepted. The important point
of the RTIP is that the data be made available in a manner that
minimizes misinterpretation. This will enable another system to
retrieve the available information without customizing a format for the
data. The RTIP is not requiring the implementation of new data
collection systems to meet all of the data exchange formats identified,
but it is assumed that over time, more data will become available and
it should be provided in the formats established.
Further, the RTIP is concerned with real-time information. It is
essentially a stream of data made available to other systems over a
center-to-center interface. Even though there are no proposed storage
requirements within the scope of the RTIP, it is good practice.
Transportation Management Systems, ISPs and the Planning Community will
likely gain from applications that make use of the archives of the
real-time information.
The information will address real-time traffic and travel
conditions that facilitate management, operations, and decision making
on the part of transportation system operators and the traveling
public. This information should improve the security of the surface
transportation system, address congestion problems, support improved
response to weather events and surface transportation incidents, and
facilitate national and regional highway traveler information.

Operational Scenarios

From a Traffic Management Center Operator's perspective, the RTIP
will provide more comprehensive information on the operator's console.
Information collected from neighboring systems, in other jurisdictions,
such as a freeway management system, may inform the operator that there
is an incident in the outbound lanes from the neighboring system. The
operator can use this incident information from the neighboring agency
to inform freeway service patrols of the issue and to take appropriate
response, to place information on Dynamic Message Signs (DMS) to inform
travelers on the outbound facilities of the incident, or to implement
diversion plans to diffuse the impact.
The Traffic Management Center software interface may be configured
to accept and process this external information but the information
would be received in a standard data exchange format making it possible
to design the interface once for that information no matter where it
originated.
From the traveler's perspective, they receive their transportation
information from an Information Service Provider (ISP) who collects
traffic and travel conditions information from their own as well as
external sources such as traffic management centers and transit
management centers. The ISP processes the information and makes it
available as a service or product to the traveler. The ISP would
collect the information from the various sources over an interface
using the standard data exchange formats established under the RTIP.
In these instances, the data exchange formats are the constant.
This enables agencies to collect from other systems and provide
information externally without establishing a different data exchange
format with each system interface. This reduces the complexity of each
system involved regarding interface definition, implementation, and
maintenance. Each organization involved in this scenario can anticipate
the types of information that will be received.
The data is real-time and not stored by the source system. It is
essentially a data feed. It is likely the subscribing organization
would establish the connection to the source, retrieve the information
needed, and store any information required for other purposes such as
transportation planning or research. In addition, these are information
exchanges only. No device control is facilitated or addressed by the
RTIP.

Summary of Impacts

The impacts of the RTIP will be the planning for existing system
upgrades

[[Page 58351]]

for the standard data exchange formats, the update of regional
architectures to reflect the data exchange formats and interfaces, and
the deployment of those formats for data exchange and the interface
they are made available on.
This document contains the high-level specifications for the data
exchange formats to support the RTIP. These high-level specifications
have been used to identify standards elements that satisfy the needs of
the RTIP based on these specifications. The high-level specifications
defined in this document bound the scope of the RTIP.

Specifications

The National ITS Architecture was used as a source of information
for the Concept of Operations and the functional specifications. The
RTIP concept was mapped to the National ITS Architecture definition.
The ATIS01-Broadcast Traveler Information Market Package was used to
start the mapping process. The interfaces identified were tailored
based on the following interface criteria:
Focus on center-to-center interfaces
Remove request flows
Remove control flows
Include system operation and conditions information
Include information of operational use to other systems
Include information of use to travelers
Remove duplicate flows
The interfaces presented by the National ITS Architecture mapping
include:
Traffic Management Information
Road network conditions
Road weather information
Traffic information coordination
Road network probe information
Traffic incidents
Air quality data
Maintenance and Construction Management
Maintenance and construction work plans
Roadway maintenance status
Work zone information
Transit Management Information
Emergency transit schedule information
Road network probe information
Transit and fare schedules
Transit incident information
Transit system data
Information Service Provider Information
Broadcast information
Road network probe information
Traveler information
Emergency traveler information
Parking Information
Parking locations
Parking availability
Emergency Management Information
Evacuation information
Disaster information
Given the Concept of Operations and the interfaces from the
National ITS Architecture as a starting point, the functional
specifications associated with each information flow in the National
ITS Architecture were examined along with the related process
specifications and data flows to generate a tailored set of high-level
specifications. These high-level specifications were refined and those
refined specifications were used to identify the data exchange formats
within the existing ITS Standards that apply to the RTIP. The resulting
specifications are provided in the first 3 columns of the Table in
Appendix A. In the specifications, the subject system is referred to as
the Real-Time Information Program (RTIP). The RTIP can be any system
that would be satisfying Section 1201.

Standards Reference

The ultimate goal of this document is to provide a reference
between the specifications of the RTIP defined in Section 1201 and the
data exchange formats established in the ITS Standards. The table in
Appendix A maps the specifications to the messages required to provide
the functions in the Real Time Information Program (RTIP). The
functional specifications are grouped under broad functionalities of
RTIP. The specifications described under the ``General Specifications''
category articulates the methods by which the logical traffic network
information in a center-to-center (C2C) communications environment
would convey traffic, incident and other information based on the node
(a geographic point) and links (road segment between two nodes) in the
area.
The messages in the referenced standards (SAE J2354, TMDD, IEEE
1512) are defined in such a way that several different submessages are
packaged in a wrapper message. All of the submessages in the wrapper
message are defined as an optional element so that a local implementer
can use only the submessage(s) which are necessary to support its
system's specification. The mapped messages for the specification(s)
also indicate which submessage(s) needs to be used.
As an example for implementation, consider the specification and
subspecifications of 1.4. A RTIP implementer will need to use the MSG--
Public incident description (PID) message from IEEE 1512 Base Standards
populated with detour and closures information for sending it to the
intended target center. This PID message has the wrapper message named
DF--IDX--Wrapper which wraps detour and closure submessage
(impactReports) as well as most of the other submessages from IEEE 1512
Base, IEEE 1512.1, IEEE 1512.2 and IEEE 1512.3 standards. But for
sending detour and closures information the DF--IDX--Wrapper needs to
have only the value of impactReports entry which has detour and
closures information while all other submessages can be omitted as they
are defined as optional and do not need to be included.
Most of the specifications have messages mapped to them taken from
existing standards. A list of specifications for which there is no
related message in the existing standards is provided below.
3.4 The RTIP shall provide information about the changes to transit
services during an evacuation.
3.6 The RTIP shall provide transit alerts and advisories pertaining
to major emergencies or disasters.
The ITS standards referenced in Appendix A feature the following
versions. Please note that ITS standards evolve over time, and that
there may be a revision to this table in the future:
TMDD--Standards for Traffic Management Center to Center
Communications, ITE/AASHTO, Version 2.1, June 1, 2005.
