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 ▲]

The connection between settlement sites and water bodies has been the most prominent characteristic of the Stone Age settlement patterns in North-Eastern Europe. Geologist and archaeologist Constantin Grewingk stated already in 1865 that in the Eastern Baltic region “Stone Age people lived by the sea and rivers”. Although there was no empirical data at that time, the following discoveries confirmed this claim. The connection is so obvious that archaeological sites are effectively used as a proxy data for reconstructing past shorelines that have been changing due to isostatic land uplift and changing hydrological conditions. The goal of current paper is to give a statistical description of the settlements’ position relative to the shoreline. The case study is based on the Stone Age settlement site locations in Southern Karelia, Finland. The region is characterized by several water bodies, including lake Saimaa, as well as several smaller lakes and rivers. A small amount of settlements in the south-eastern part of the study area is also located on the paleoshorelines of the Baltic Sea. The following questions are asked: how many and what kind of Stone Age sites are shoreline-connected? How to statistically describe the distribution of distances from the settlements to the closest shoreline? Because of the abundance of lake shores in the region, it also has to be judged if the settlement pattern was formed by the economical/cultural lifeways of past inhabitants or was it just enforced by the landscape. To answer this question, it is analysed if the distribution of distances to shoreline of Stone Age sites significantly differs from the ones of later periods? [less ▲]

Consisting of four entities, regions or states, located in the heart of Europe, the Greater Region SaarLorLux has long been considered a territory with a rich industrial past of great dynamism. Among the many branches of activity, there is one that has long been a flagship of its skills: ceramics. The term "ceramics" covers a certain number of very different products in terms of their appearance and properties, all made from fired clay. Over time, manufacturing techniques have evolved to produce less and less porous and finer designs. The applications of this material have thus expanded considerably. Working with clay is a long-standing tradition in this region, as the first ceramics discovered at archaeological sites are 7 000 years old. So, for thousands of years, potters made objects out of fired clay. [less ▲]

Settlement patterns have been one of the central products of Stone Age archaeological research. Because of long time spans and very scarce information, scientific explanations of the patterns are usually limited to just defining the areas of the phenomena of interest. Any further deductions about past communities tend to be without additional proof and thus presented as hypotheses in scientific literature. In this paper we introduce a study that seeks to create a general framework for modeling the emergence of settlement patterns. The central concept for modeling is the human / social perception of the environment and how it is related to potential residential space – places that can be used for human habitation. We hypothesize that the human perception can be used to simulate the processes of emergence of immigration and seasonal mobility. The first goal of the research is to identify possible knowledge sources (eg. paleoecology, geography, geology, anthropology) that give information about residential mobility of pre-agricultural societies. The second goal is to translate selected knowledge to algorithmic representation and evaluate its usability for modeling. The purpose of which is to find the determining factors in the emergence of the settlement patterns and to distinguish between emerging and irreducibly complex phenomena. [less ▲]

The administrative division of the Greater Region (2008: 65,398 km², 11.4 million inhabitants) is not homogeneous. The different areas of the Grande Région have different statuses: The Grand Duchy of Luxembourg is a sovereign state, Wallonia is a region of Belgium, Lorraine was until the end of 2015 one of the 26 regions of France, is from 1.10.2016 part of the new region Grand Est, Rhineland-Palatinate and Saarland are German Länder. The size and number of inhabitants of the municipalities as well as their competences differ significantly from each other, not least because there has been no municipal reform in France, but also because of the different political and economic structures.

The textile industry has had a long time to transform the industrial landscape of the Greater Region SaarLorLux, as it is one of the earliest industrialised economic activities. Often born on a proto-industrial basis, it was mechanised very early on in most of its branches (from spinning to weaving, dyeing, bleaching and printing to clothing) and thus formed, sometimes, vast industrial concentrations, which imposed themselves alongside more modest establishments. However, this pioneering industry is now often presented in Europe as an activity of the past, the bulk of which has been relocated to low labour cost countries in the South. [less ▲]

With the 2002 introduction of the euro as a common currency in Europe,the possibility has emerged to assess international mobility using this new tracer, given that every coin bears a specific national side. Using a simple two-country framework, four dynamic modeling strategies were designed in order to simulate the diffusion of coins and to understand how this diffusion is affected by population size, mobility rates and coin exchange processes. Methodological implications are raised with respect to aggregation, synchronicity and stochasticity issues. Although each model converges to an equilibrium, the time to reach this end stage and the level of coin mixing in each country strongly varies with the modeling strategy. Calibration is undertaken with French data, using mobility rates as adjustment variables. The experiment shows that convergence to a perfect mix of coins can only be obtained if reciprocal exchanges are modeled, with a time horizon around 2064 - while non-reciprocal models indicate an imperfect mix converging in the year 2020 at the latest.

A new method is proposed for characterising local urban patterns at the scale of a large urban region. The approach overcomes the difficulties of surface-based representations of built-up morphologies and provides an efficient way to account for the proximity of built and non-built land. The strength of the approach resides in the direct use of the coordinates of each building, a very parsimonious input of external parameters, and a local spatial statistical perspective. The method consists in, first, constructing and clumping the Minimum Spanning Tree (MST) that links each building to its neighbours in order to obtain connected urban and suburban graph subsets, and second, measuring a Local Index of Spatial Association (LISA) on inter-building distances in order to characterise patterns. The method differentiates heterogeneous settlements from statistically significant homogeneous clusters with either long or short connections between buildings. The method is applied to the Southern periphery of Brussels (Belgium). [less ▲]

The number of foreigners living in Luxembourg is still rising and represents today about 48% of the inhabitants. This study focuses on the description and mapping of the place of residence for the different nationalities living in Luxembourg. It seeks to underline differences through indicators built from the 2011 census data. We focus on the territorial distribution of the different nationalities by taking into account the urban structure and distance to jobs. If differences according to nationalities in the residential behavior of households can be empirically identified they may raise issues of spatial equity and (un)equal accessibility to job market. We analyse whether the geographic location of different nationalities in Luxembourg is linked to urbanisation level, the distance to the “poles d´emploi” or general accessibility to jobs. [less ▲]

Urban green space is important for making cities sustainable. It provides environmental benefits and makes cities attractive to people. Extensive evidence exists on their benefits but is lacking in quantifying how and whether socio-economic benefits of green space accrue to all households or only a portion depending on their socio-economic status and residential location. From urban economic theory we know that residential markets sort households by income along an urban–suburban continuum and the housing-transport-costs trade-off. This trade-off can however be dominated in the presence of exogenous central amenities (parks) or endogenous effects (high income attracting high income) and pull better-off households toward the center, adding discrepancies in accessibility to green amenities by different socio-economic groups. Tiebout's hypothesis implied that marginal benefits from localised amenities are the same for all households in a given location but empirics point to non-efficient sorting and endogenous effects (socio-economic sorting) in the demand for localised amenities in general. We address these questions based on results of a survey conducted along an urban-suburban continuum in Brussels (Belgium) in May 2016. The survey includes around 500 respondents sampled across (non-park) public space and malls to reach both users and non-users of green space and cover the variety of residential locations (good or bad provision of green / distant or far from the CBD). We analyse the role of proximity, size and quality of public green space on its use across different socio-economic attributes and residential/job places and stated willingness-to-pay and substitution possibilities with private green space.

In this paper we analyse the profile of land use and population density with respect to the distance to the city centre for the European city. In addition to providing the radial population density and soil-sealing profiles for a large set of cities, we demonstrate a remarkable constancy of the profiles across city size. Our analysis combines the GMES/Copernicus Urban Atlas 2006 land use database at 5m resolu- tion for 300 European cities with more than 100.000 inhabitants and the Geostat population grid at 1km resolution. Population is allocated proportionally to surface and weighted by soil sealing and density classes of the Urban Atlas. We analyse the profile of each artificial land use and population with distance to the town hall. In line with earlier literature, we confirm the strong monocentricity of the European city and the negative exponential curve for population density. Moreover, we find that land use curves, in particular the share of housing and roads, scale along the two horizontal dimensions with the square root of city population, while population curves scale in three dimensions with the cubic root of city population. In short, European cities of different sizes are homothetic in terms of land use and population density. While earlier literature documented the scaling of average densities (total surface and population) with city size, we document the scaling of the whole radial distance profile with city size, thus liaising intra-urban radial analysis and systems of cities. In addition to providing a new empirical view of the European city, our scaling offers a set of practical and coherent definitions of a city, independent of its population, from which we can re-question urban scaling laws and Zipf’s law for cities.

We examine how geographical structures impact diffusion processes within a regional system. From the example of euro coin diffusion across countries, we show how the relative position and population endowment of regions impact our understanding of interregional mobility, beyond simple spatial interaction effects. The mix of coins of different origins is a complex but unique trace of the movement of individuals within a common currency area, potentially revealing a new facet of European integration. We simulate an individual-based dynamic model where agents move and exchange coins across regions. We analyse the convergence towards a homogeneous mix of coins through time for a series of different theoretical spatial systems. This sensitivity analysis demonstrates the impact of the regularity and aggregation levels, or centrality/periphery effects, on spatial diffusion dynamics. We then calibrate the model against empirical data for the regions of 5 European countries and provide estimates of mobility rates, distance decay and population attractiveness factors, affecting the diffusion of coins, hence international movements and European integration.

Many municipalities assert bicycle sharing systems (BSS) as having many benefits, justifying their adoption, yet few explicitly state the purpose of their system making comparison or determination of success impossible. In addition, the apprehension of many BSS operators to share data further hinders comparison. This paper estimates the number of daily trips from publicly available data for 75 BSS case studies across the world and provides trips per bike per day scores as a comparison of performance and success. Results reveal that a third of case studies have fewer than the psychologically important one trip per bicycle per day. To ascertain what factors are associated with this metric we estimate models with independent variables related to system attributes, station density, weather, geography and transportation infrastructure. Our analysis provides strong evidence undermining the ‘network effect’ promoted by influential BSS policy makers that expanding system size increases performance. Finally our results describe and discuss causal variables associated with higher BSS performance. [less ▲]
