Integrated Land Use & Transport Modelling
Integrated Land Use Transportation Environment (ILUTE) Modelling System
Integrated Land Use- Transportation Modelling is one of the major research thrusts in the Transportation Engineering Section. The ILUTE modelling system is an extended experiment in the development of a large scale microsimulation model of the Greater Toronto Area and other Canadian urban areas. It is an attempt to better understand the complex multi-faceted relationships between each of the individual players in an urban system, how they make decisions about where and when to travel, and how the complex relationships cause the urban system to evolve over time.
Policy Issues 
There exist a range of policies that could have a real impact on the automobile emissions and congestion generated in an urban system, however, it is impossible to assess the impact of such policies without systematic analysis using quantitative models. Issues/ policies which are particularly in need of assessment include:
1) Municipal and regional land use policies,
2) Road pricing and taxation options,
3) Transit policies,
4) Demographic and socio-economic shifts,
5) Technological advances and their impacts.
The ILUTE Model 
ILUTE is an integrated urban modelling system that consists of a "behavioural core" of the following four inter-related components:Land Development, Location Choice, Activity/Travel, and Auto Ownership.
Each of these behavioural components involves a complex set of sub-models that incorporate supply/demand interactions, and interact among each other. For example, land use evolves in response to location needs of households and firms, and people relocate their homes and/or jobs at least partially in response to accessibility factors.
Microsimulation and Behavioural Models
The term "microsimulation" has been applied to a broad set of uses in a variety of disciplines. In the context of the ILUTE project, microsimulation is a method of modelling where the behaviour of the individual entities is simulated over time. The cumulative effects of these individual behaviours form the overall behaviour of the system. The objects or actors in the system represent real-world entities such as persons or firms. The behaviour of these objects is designed to reflect the behaviour of their real world counterparts.
Behavioural submodels in ILUTE include:
Data Synthesis
Population updating
Activity/Travel Modelling
Housing Supply
Residential Mobility
Auto Ownership
