Intelligent transport infrastructures are key to the sustainability of the UK’s economic and
environmental development. The Government is committed to a fairer taxation policy for road
usage and at the same time manage congestion, by introducing a road user charge based on
time of day, class of road etc. The private sector is already piloting motor insurance schemes
to base premiums on location, time of day and how vehicles are driven. The Home Office is
using prisoner tagging schemes to track offenders. European legislation is being introduced
to ensure the movement of live animals is tracked to control the spread of contagious diseases.
The movement of dangerous goods, such as nuclear fuels, will have to be tracked to comply
with new legislation.
All these policy initiatives require position and time data - which can be provided with
least impact on the environment via satellites. These initiatives will serve to increase both
government and public dependence on the uninterrupted provision of signals. The success of
these policies is linked strongly to both the system performance and the guaranteed availability
of signals, and implicitly requires Galileo and not just GPS. Galileo provides increased signal
availability, significantly superior signal design, a service guarantee and integrity of service.
The use of GPS plus Galileo delivers the best performance of all, by combining signals from
the two constellations (nearly 60 satellites), dramatically increasing signal availability.
The use of satellite navigation in road vehicles is growing and systems are anticipated to
be installed in the majority of vehicles in 10 years. Satellite navigation brings unique benefits
to road users in terms of time saved, reduction in accidents, theft and emissions.
This level of satellite navigation penetration in road vehicles will help save road users
considerable time (other studies estimate this at 15%). This should lead to savings of over £10
billion for UK drivers (both commercial and leisure) and further savings to society from reduced
emissions of £0.5 billion.
Satellite navigation systems such as eCall that enable the emergency services accurately
and speedily to locate accidents on the roads will help save lives and reduce serious injuries.
Speed alert/advanced driver assistance systems which give collision and speed warnings will
also reduce the number of accidents. The total benefit to the UK from reduced accidents is
estimated at £1.7 billion per year in the future.
Satellite navigation systems that enable stolen vehicles to be tracked and then disabled
are estimated to be worth £1.5 billion per year to the UK in the future. Statements from the
police confirmed the success of small scale trials of such systems.
Total UK benefits from the use of positioning systems in the aviation industry, enabling
more efficient use of airspace, are estimated at around £1.4 bn per year. This will increase
as Galileo comes into operation with consequent increase in accuracy. The UK is playing a
leading role in establishing early signal and service demonstrations.
The improvements in transport capacity and flow resulting from GNSS (Global Navigation
Satellite System) enabled traffic management will permit continued growth of the economy
without the pressure for major changes or additions to transport infrastructure, restrictions on
social mobility, increasing congestion and the environmental damage experienced hitherto.
This will break the link between economic growth and the growth of transport.
