Common Logical Data Model: Basis for Global ITS Innovation
By comparison, Figure 5 provides the
equivalent portion of the physical data
model for the basic safety message (BSM) as
defined in SAE J2735, which is used in the
United States. 37

independent efforts to solve the same or
related problems and practical realities
prevent real-time collaboration. The
methodology presented in this paper
accepts the existence of these two solutions
as a fact of life and proposes how to
overcome integration challenges once
competing
solutions
exist
without
attempting to impose a new solution. This
will be achieved by developing a higher-level,
While both standards define very similar
information (i.e., latitude, longitude,
elevation, speed and heading of the vehicle)
for the same purpose (i.e., reporting the
vehicle location and motion), the rules and
structures used to convey this information
are quite different.
Competing solutions such as these should be
expected when different groups undertake
