Overview of an international study to compare models and evaluate land‐use and transport policies

Abstract

This paper is the last of a series published in Transport Reviews describing the results obtained from Phase 2 of the International Study Group on LandUse/Transport Interaction (ISGLUTI). In this second phase some interactive models were applied to several cities, and some cities examined by several models, to enable a rigorous comparative evaluation of the various models to be carried out. The paper draws together the main findings of the study, commenting on the performance of the models, looks particularly at the impacts of transport and landuse policies on the cities examined, and discusses the lessons learnt. The act of applying the models to completely different areas proved to be a significant test of the models, and further highlighted their particular strengths and weaknesses, taking account of the ease of transferring to different cities. The study identified those policies where the interaction between land use and transport was particularly strong and those where it was surprisingly weak and showed how the interaction over the longer term could modify the initial impacts. The results have shown how the effects of policies depend on the size and characteristics of the city to which they are being applied. The paper concludes that the more exacting tests of Phase 2 have demonstrated more clearly than hitherto how useful the models are for particular tasks and have given important insights into the impacts of the particular policies tested.

Designing optimal urban transport strategies: The role of individual policy instruments and the impact of financial constraints

“…studied, but did not optimise, land use and transport strategies (Paulley and Webster, 1991); work by TRL with their Transport Policy Model, which indicated the relative merits of policies based on public transport and demand management in five UK cities, but made no attempt at optimisation (Dasgupta et al, 1994); and the PROPOLIS study (Lautso et al, 2004) where a comparative study of the performance of a range of policy instruments, and selected combinations, in seven European cities, was conducted using three different land use transport interaction models. This paper is one of the several reporting on our work which aimed to cover these issues by making use of three time-marching models: MARS (Pfaffenbichler, 2003;Pfaffenbichler, 2003), TPM (TRL, 2001) and START-DELTA (Simmonds and Still, 1999).…”

Resilient transport systems to reduce urban vulnerability to floods in emerging-coastal cities: A case study of Ho Chi Minh City, Vietnam

“…Urban planning for land-use and transport are intertwined in terms of spatial dimensions (Waddell, 2011;Southworth and Ben-Joseph, 1995;Paulley and Webster, 1991). As spatial plans for urban development are approved, these act as a driver for an expansion of the road network leading to new critical (and potentially vulnerable) links and nodes.…”

Editorial

“…The group also operates an informal electronic mail network (PLANET) that is accessible from the Internet and Bitnet networks. At an international level, the International Study Group on Land-use/Transport Interaction (ISGLUTI), has conducted two landmark studies comparing nine operational urban models from seven countries (Paulley and Webster, 1991;Webster et al, 1988).…”
