The increasing attractiveness of Luxembourg as a place to work and live puts its land use and transport systems under high pressure. Understanding how the country can accommodate residential growth and additional traffic in a sustainable manner is a key and difficult challenge that requires a policy relevant, flexible and responsive modelling framework. We describe the first fully fledged land-use and transport interaction framework (MOEBIUS) applied to the whole of Luxembourg. We stress its multi-scalar nature and detail the articulation of two of its main components: a dynamic demographic microsimulation at the scale of individuals and a micro-spatial scale simulation of residential choice. Conversely to traditional zone-based approaches, the framework keeps full details of households and individuals for residential and travel mode choice, making the model highly consistent with theory. In addition, results and policy constraints are implemented at a very fine resolution (20m) and can thus incorporate local effects (residential externalities, local urban design). Conversely to fully disaggregated approaches, a linkage is organized at an intermediate scale, which allows one (1) to simplify the generation and spatial distribution of trips, (2) to parallelize parts of the residential choice simulation, and (3) to ensure a good calibration of the population and real estate market estimates. We show model outputs for different scenarios at the horizon 2030 and compare them along sustainability criteria. [less ▲]

While commuting allows workers to take part to the economy, this specific trip represents a non-negligible share of the total trips undertaken by individuals. Because of the repetitive pattern both in time and space of the home-to-work trip, different transport policies can be implemented in order to reduce some of its negative impacts. Travel Demand Management (TDM) measures aim at reducing the transport demand or inducing a modal shift towards active or public transport modes. Too often, these strategies, by focusing narrowly on the home-to-work trip, do not take into account the complexity of the individuals’ daily activity chain. Indeed, the complexity of the activity pattern might impede some workers to use public or active modes for the commuting trip despite, for instance, a very short home-to-work distance. Results of a Structural Equation Modelling (SEM) approach indicates that, for working days, socio-demographic variables affect more car use than activity-chain complexity. Thus, the proposed TDM measures aiming at decreasing car use for commuting takes into account the daily activity behavior but also suggest ways to deal with individual’s characteristics [less ▲]

We present the modelling strategy of the research project MOEBIUS, which aims at simulating future urbanisation and commuting mobility, including modal split, under various planning conditions. MOEBIUS is similar in its objectives to a Land Use and Transport Interaction (LUTI) model, although very modular in its implementation and with ability to deal with very fine spatial resolution inputs and outputs. We simulate (i) the future potential urbanisation in Luxembourg, (ii) the population and its spatial distribution, and (iii) the daily mobility (commuting pattern and travel mode choice) at a disaggregated level.
