Navigation Systems Seriously Undermine Road Safety

    - Software Errors are Being Ignored

    THE HAGUE, The Netherlands, Jan. 8 /CNW/ - Using a new research method,
the Stichting Onderzoek Navigatiesystemen ("Navigation Systems Research
Foundation") has discovered why navigation systems cannot find ring roads in
cities. Software errors are the cause. The Foundation predicts a catastrophic
development if the authorities do not intervene: more traffic accidents and
casualties, and side roads becoming jammed with volumes of traffic for which
they were not designed.
    Almost none of the navigation systems tested take sufficient account of
the hierarchy in the road network. As a result, motorists are unnecessarily
being turned into 'kid killers' by being sent through designated low-traffic
residential areas and roads which are not designed for through-traffic. The
navigation systems do not appear to be able to find ring roads.
    Software errors are the cause. TomTom blames the problem on the
information supplied by the authorities, but that cannot be true, as Nav4All
(a free navigation system for mobile phones) does in fact send motorists to
their destinations via the appropriate roads.
    A direct consequence of these software errors is that the automatic
traffic jam avoidance features of TomTom and other navigation systems cause
local roads to become jammed with volumes of traffic for which they were not
designed and for which they are not suitable. This increases the number of
traffic accidents and casualties, and disturbs the peace and the environment
of residential areas.
    The authorities have a responsibility to take action in good time.
Systems which unnecessarily endanger road safety and the flow of traffic must
be banned. At the moment, the problem is still relatively small, but in a few
years time, when everyone is using navigation systems, the consequences will
be incalculable.

    Note to Editors

    The objective of the Navigation Systems Research Foundation is to carry
out comparative research into the market for navigation systems, in order to
increase market transparency, both nationally and internationally. In so
doing, the Foundation aims to make a contribution to improving road safety.
