This paper considers the implications of possible “lifestyle models” for land-use modelling and appraisal, drawing on experience in previous land-use microsimulation and in extending appraisal from transport to land-use transport appraisal.
The idea of “lifestyle models” has evolved from a series of seminars at ETC in an attempt to address some important deficiencies with current methods. This paper considers the implications of possible “lifestyle models” for land-use modelling and appraisal, drawing on experience in previous land-use microsimulation and in extending appraisal from transport to land-use transport appraisal. In particular it will respond to issues raised by the papers from Peter Davidson and Helen Porter.
This paper will consider the issues which would arise in attempting to appraise alternative interventions within a lifestyle model. It should be noted at the outset that the intention is not to appraise the merits of different lifestyles in themselves, but to appraise the benefits and disbenefits accruing to residents given the ways in which their lifestyle preference affect both their choices and their perceptions. That said, different lifestyles may well have different implications – for example in terms of different levels and forms of mobility – which will have different impacts on other people and on the environment, and these impacts will need to be taken into account in appraisal.
The “lifestyle modelling” concept necessarily involves representing choices and responses in both “land-use” (eg in household location decisions) and in “transport”. The paper will draw on experience in land-use modelling (including microsimulation of household/population change) and on progress to date in the development of methods of combined land-use/transport appraisal. It will seek to identify potential ways forward which would be helpful in addressing current and foreseeable future issues in land-use and transport planning and in other aspects of government.
