Considerations to Developing a Regional Real Time Transit Data
Feed
• No consensus among regional transit agencies on a unified real time feed.
• Major differences in what is provided in currently available feeds.
• Not all agencies have real time feeds available.
• Project will result in a region-wide standard

(RTSMIP) provides traceability between requirements and SIRI Design
• Transit Communications Interface Profiles (TCIP)• RTSMIP provides traceability between requirements and TCIP
Design
• General Transit Feed Specification – realtime (GTFS-RT)• Not an actual standard, but a very popular specification• No mapping in RTSMIP• A mapping of GTFS-RT design to RTSMIP requirements will be
developed

Conclusion
• Vision of Interoperability and efficient scaling of technology, nationally, across public agencies remains important;
• GTFS, as an open standard, created a marketplace beyond the wildest dreams of the National ITS Architecture and Standards;
• Google did not do this out of dedication to the National vision of interoperability – they wanted to provide a “service that matters” to customers;
• Achieving efficiencies in ITS transit deployment (for operations) likely goes beyond the purpose or goals of GTFS Community;
• What role do Federal standards play in building on what GTFS has taught us?

Background & Purpose
• Section 1201 of SAFETEA-LU required a real-time system
management information program in all States
• The capability to monitor, in real time, the traffic & travel
conditions of major highways, and to share that
information to improve the security of the network
• To address congestion, to support response to weather
events & transportation incidents, and facilitate traveler
information.
• SAFETEA-LU also required a data exchange format to be
established to ensure that the data provided by highway &
transit monitoring systems can readily be exchanged across
jurisdictional boundaries.3

Background & Purpose (Cont’d)
• The initial requirements: 23 CFR 511 was developed which required each state to establish & operate a Real-Time System Management Information Program (RTSMIP) capable of gathering and making available (not delivery) the data for traffic and travel conditions.
• The development of a Data Exchange Format Specification (DXFS) and Implementation Guidance was in response to the second provision in SAFETEA-LU
• Section 1201 addresses the requirements of RTSMIP as Regional ITS Architectures are reviewed and updated

Background & Purpose (Cont’d)
• DXFS is developed to assist users
• To specify and implement an RTSMIP, and
• Support the need of States for a specification that satisfies
the rule.
• DXFS not only covers all the information defined in 23 CFR
511, but also extends to include transit information and
additional traffic information that is relevant to the
exchange of data between agencies and others.

DXFS Scope
• DXFS can be used to define the information exchanges across
system-to-system interfaces
• Provides interoperability of systems that implement the
DXFS.
• DXFS does not specify communication protocols
– Identifies standards at the Information level.
– Refers to existing standardized protocols that can be
used for transferring the data.

DXFS Objective
• Primary objective of the DXFS is to establish a standards-
based specification of key RTSMIP interfaces.
• Scope of the DXFS is the set of interfaces used to send
traffic, transit, transportation-related weather, and traveler
information from one agency to another.
• Provision of data directly to travelers is not part of the
scope of the specification.
• DXFS was developed with consideration of the many
stakeholders’ independent goals & objectives
• Used a Systems Engineering process of verification &
validation at each key stage of the DXFS development.

Audiences for DXFS
The DXFS has been developed to assist the following groups of users
to specify, implement, or support an RTSMIP:
• Transportation Agencies includes state DOTs & regional
transportation-related organizations (e.g., a municipal DOT, Public
Works, or a transit agency)
• Public Safety Agencies includes state, county, or local public safety
agencies
• Traveler Information Organizations (Public or Private). This group
includes providers of traveler information whether public or private
• Development Contractors. This group includes contractors who
have been hired to develop procurement packages or to develop
RTSMIP-related projects

Systems Requirements
• DXFS systems requirements define the formal requirements to satisfy
all user needs
• Needs-to-Requirements-Traceability-Matrix traces each user need
to one or more requirements.
• The functional requirements are presented in two broad categories as
follows:
• Data Exchange and Operational Environmental Requirements.
Define the required behavior of the system in exchanging data
across the communications interface based upon the features
identified in this document.
• Architectural Requirements. Define management of the interface
connections between centers, i.e., connection management, error
handling, and the two basic methods of making connections (e.g.,
request/response and subscription/publication).21

Standards Referenced by the DXFS
22
DXFS Functional Area
Standard Description of Standard
Traffic Management TMDD The Traffic Management Data Dictionary (TMDD) provides for information and control exchanges related to real-time roadway and traffic information, incidents, construction, and roadway weather.
Transit Management
TCIP The Transit Communications Interface Profile (TCIP) covers transit communications between centers, and centers and transit vehicles. TCIP provides traveler information on real-time transit vehicle location, and predicted transit vehicle arrival/departure.
Transit Management
SIRI The Service Interface for Real time Information covers transit communications between centers, and centers and transit vehicles. SIRI provides traveler information on real-time transit vehicle location, predicted transit vehicle arrival/departure, and predicted transit trip travel time.
National Weather Service Weather Alerts
OASIS CAP The Common Alerting Protocol (CAP) is a simple but general format for exchanging all-hazard emergency alerts and public warnings over all kinds of networks. CAP allows a consistent warning message to be disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the warning task.

• Requires a tag in vehicle
• Treats owners of vehicles without tags as violators
• All-Electronic Tolling (AET)
• No stopping to pay toll for everyone
• Customers without tags are no longer treated as
violators at the point of toll
