Common Logical Data Model: Basis for Global ITS Innovation
worldwide. Furthermore, using an open
GitHub environment allows this effort to
more easily reflect the entire ITS community
rather than just the perspectives of a group
of experts within a standards development
organization (SDO). The resulting, broadly-
accepted concept model will then serve as a
baseline for developing a more detailed
logical data model which ISO/TC 204 hopes
to develop in a similar manner while
coordinating this development with even
larger efforts related to Smart Cities and the
Internet of Things (IoT). The result will be a
model of ITS data with clear rules on
translating data from one data format to any
other data format through the common
logical data model formats. The Industrial
Internet Consortium (IIC) can proactively
influence the work through liaised relations
with ISO.

There are over 25 distinct groups developing
open standards and specifications related to
Intelligent Transportation Systems (ITS),
ranging from internationally recognized
standards groups such as the International
Organization for Standardization (ISO) to
national and regional standards groups such
as
the
European
Committee
for
Standardization (CEN) and informal groups
that
develop
widely
referenced
specifications such as General Transit Feed
Specification (GTFS). These distinct groups
are made up of industry experts with
common business interests in quickly
developing documents; already, these
groups have developed over 1,000 ITS
standards, specifications and documents,
and the number continues to grow. While
some cross-pollination of innovative ideas
occur, coordination among groups is
challenging due to travel costs, copyright
issues and the need for timely products
versus the time required to build broad
consensus. As a result, various groups often
develop similar terms and data definitions
that can lead to confusion when comparing
materials from different sources. In some
cases, these differences can potentially have
safety implications. ISO/TC 204 (ISO
Technical Committee 204) is beginning to
address this issue through two work
products, a vocabulary and a logical data
model. These standards will facilitate the
sharing of Probe Data to facilitate global
interoperability of ITS. The vocabulary
document, which includes a formal concept
model, is currently under development on
GitHub allowing input from industry experts
