HILLINGDON UNITARY DEVELOPMENT PLAN - London Borough ...

increasing number of orbital north-south traffic movements, now served by the M25 and Hayes and
Yiewsley by-passes.
2.65 The presence of these high capacity radial and orbital routes has helped stimulate pressure for
large town centre and out-of-centre office and retail developments dependent for their viability on the large
catchment areas these routes open up. The number and length of the trips this type of development
generates increases the total vehicle miles compared with that arising from a pattern of smaller
developments drawing upon smaller catchment areas. The effect is increased congestion and journey
times, coupled with reduced standards of safety and environmental quality.
2.66 The Government is committed to reducing the United Kingdom's emissions of carbon dioxide
(CO 2 ) to 1990 levels by the year 2000 and the Department of the Environment has issued guidance on the
contribution of land use planning to reducing transport CO 2 emissions. (PPG13 'Transport' (1994). In
signing Agenda 21 at the Rio "Earth Summit", which binds signatories to integrating land use and transport
planning to encourage development patterns that reduce transport demand, the Government has reinforced
its commitment to the guidance in PPG12 to encourage patterns of development that make shops, offices
and other services accessible on foot or by cycle or public transport for the majority of customers,
employees and visitors, and to discourage those which are accessible principally by private car. These
issues have been taken into account in identifying areas for development and in formulating policies in this
Plan.
2.67 Government guidance in PPG13 'Transport' (1994) has been fundamental in improving the
integration between transport and land-use planning and a foundation for the Government's Sustainable
Development Strategy. The key elements of the guidance in reducing the growth in length and number of
motorised journeys, encouraging alternative means of travel which have less environmental impact and
reducing the reliance on the private car have been incorporated both in Strategic Advice (1994) and draft
revised Strategic Planning Guidance (1995). The Council's Transport Strategy and Policies in this Plan,
particularly through the public transport initiatives and car parking objectives, have been based on PPG13
and revised RPG3 (1996).
2.68 LPAC's 1994 Strategic Advice proposed significant changes to the provision of car parking for
new development as a way of bringing overall changes in the usage of the private car. This approach was
endorsed by revised draft RPG3 and the Council through its policies are aiming for a gradual reduction of
the demand for parking through the introduction of maximum standards. Given the geographical layout of
the Borough and poor provision of orbital public transport these changes will be introduced incrementally.
2.69 Strategic Planning Guidance defines London's Strategic Road Network of motorways, trunk and
designated roads (Map 2). This network is statutorily defined in the Designation of Roads in Greater
London Order 1986 (SI 154). These are roads forming part of the national and London-wide road system
which are intended to carry mainly long distance traffic.
2.70 This Guidance considers the main objectives for accessibility and movement in London to be:
The need to:-
-tackle road congestion and improve air quality through better management and control of
traffic; and
-stimulate greater use of public transport, walking and cycling through a more sustainable
transport and land use pattern.
2.71 The Council in its regeneration strategy for the Hayes/West Drayton Corridor recognises the
opportunities to achieve these objectives by identifying Hayes as suitable for significant improvements to
public transport interchange facilities. With regard to the relationship between transport and development,
RPG3 (1996) encourages boroughs to promote the use of public transport and assist in the furtherance of
development proposals which facilitate new public transport links, stations or interchanges (Para 6.4).
Guidance also notes that improved rail, bus and coach links to Heathrow could also include better
