#1. An application of land use, transport, and economy interaction model

Presenter: Henry Le - Technical Director | AECOM

Governments need to assess the benefits of transport projects to prioritise investments. It is imperative for governments to have tools that can closely estimate the actual benefits and impacts of significant transport projects. Traditionally, the benefits of a transport project have been estimated by using a transport model, assuming fixed land use for the base and project case in the future. However, this approach cannot measure the impact of land-use changes as residents and businesses relocate to take advantage of lower travel and/or freight costs resulting from the project. Consequently, the benefits of the project may be underestimated or overestimated, depending on its position within the transport network and how it reshapes land use patterns in the future. To overcome this drawback, this presentation firstly presents a literature review of advances in the land use transport interaction model (LUTI), then discusses the development of a LUTI model for Victoria, Australia (VLUTI) by integrating the Victorian Integrated Transport Model with a Spatial Computable General Equilibrium model (SCGE). The land use component (SCGE) was developed to represent a highly resolved zone system, detailed classifications of occupations and industries, and spatial interactions via transport costs, and thus enables VLUTI to simulate a detailed picture of land use and transport interactions in an economic environment. The literature review also indicates limited research in applying a LUTI to estimate land use change benefits. This paper presents an application of VLUTI by looking at differences in the conventional transport benefits under both static and dynamic land use scenarios. In the static method, the land use in the project case is unchanged from the base case. In the dynamic case, the land use in the project case, at a future point in time, is endogenously adjusted within VLUTI. It also presents a method to correct, in the dynamic case, the benefits as estimated by the rule of a half, which usually assumes static land use. The paper concludes with suggestions for further developments and improvements of VLUTI.

#2. Application of LUTI modelling framework

Presenter: James McIntosh - Director | LUTI Consulting

An important part of any integrated transport and land use project is demonstrating the nexus between the transformational city building and productivity benefits unlocked by the investment in transport projects, and its pure transport outcomes delivered by the project. The modelling framework ensures that econometric modelling of these benefits is delivered in such a way that the inter-dependencies are quantified, and form the basis of a truly integrated land use and transport economic appraisal.

#3. Adventures in land use modelling – Recent developments and new frontiers

Presenter: Stuart Donovan - Principal Transport Economist and Planner | Veitch Lister Consulting

In this talk, Stuart will summarise recent research and consider its implications for land use and transport modelling and planning. Topics will include but not be limited to the effects of non-work accessibility, measurement error, vehicle ownership, heterogeneous populations, dynamic behaviour, and economic appraisal. In this presentation, Stuart will aim to provide participants with useful insights into the current state of land use modelling, relevant implications for planning and practice, and promising directions for further research.
