INTELLIGENT SPEED ADAPTATION
133. Intelligent Speed Adaptation may also have a
role in the near to medium future. Our predecessor Committee made
recommendations on its application for safety purposes.
Intelligent Speed Adaptation is a system of in-vehicle speed limitation.
The vehicle is located and provided with information about the
speed limit on the road, through a combination of a Global Positioning
System and a digital road map. This information is connected to
the vehicle's power train: throttle, ignition, fuelling system,
gearbox and brakes. The system provides in-vehicle technology
which prevents the driver exceeding the speed limit, except in
134. Initial research in the UK, funded by the former
Department of the Environment, Transport and the Regions and undertaken
by the University of Leeds and the Motor Industry Research Association,
identified that a full mandatory dynamic form of Intelligent Speed
Adaptation would lead to a reduction of 36% in all injury collisions
and of 59% in fatal crashes. There was support from many of our
witnesses for its early introduction.
As Stephen Plowden commented:
There is something ridiculous about allowing excessively
fast and powerful cars on the road and then trying, at great expense
and with only modest success, to stop people from using that power.
cameras have achieved significant reductions in collisions and
casualties. There remains potential to increase this impact not
only through the rules and arrangements which govern their use,
but also through ongoing technological developments. Time-distance
cameras improve effectiveness: the Department for Transport, Home
Office and police forces should take the steps necessary to encourage
their use and make sure sufficient resources are invested. The
possibility of using time-distance cameras to enforce 20 miles
per hour limits on residential roads should be explored by the
Department. We welcome Transport for London's efforts to secure
Home Office type approval for such equipment in order to protect
vulnerable road users through enforcement of appropriate speed
limits. Development work on Intelligent Speed Adaptation should
be continued. We would welcome the early introduction of in-vehicle
enforcement technology. The potential of Intelligent Road Studs
should also be further explored.
