A historical topographic map from the early 19th century, the Tranchot and v. Müffling map covers most of the German part of the Greater SaarLorLux Region. Müffling covers most of the German part of the Greater SaarLorLux Region. Together with the Cassini Map for the French part and the Ferraris Map for Wallonia and the Grand Duchy of Luxembourg, the situation before the revolutionary changes by the industrial revolution can be represented for most of the Greater SaarLorLux Region. In order to explain the map of Tranchot and v. Müffling for the GR-Atlas extracts from Carl, Marie-Luise 2004: "Der Hintergrund zur Kartenaufnahme der Rheinlande durch Tranchot und von Müffling im Spiegel einer Inschrift", largely based on Schmidt, R. 1973 and Effertz, P. 1990, are assembled here.

The two maps show the climate normals for average annual temperature and precipitation in the Greater Region for the period 1971 to 2000. Subject to natural variability, the weather conditions encountered over the days and seasons characterise the climate of a region. For obvious reasons of representativeness, the mathematical expression of the climate in terms of average, maximum or minimum values of various variables (precipitation, temperatures, etc.) must necessarily cover a whole range of conditions, which may be distinguished by very contrasting frequencies of occurrence.

Das Großherzogtum Luxemburg verfügte im Jahr 2008 über 238 Tankstellen. Allein 167 davon - knapp drei Viertel - liegen in unmittelbarer Nähe zur Landesgrenze. Hier kam es in den letzten Jahrzehnten zu einer unverhältnismäßig hohen Konzentration von Tankstellen als Folge des internationalen Tanktourismus, eines Phänomens, das sich aus dem deutlichen Preisvorteil des Kraftstoffs in Luxemburg gegenüber seinen Nachbarländern ergibt.

In 2008, the Grand Duchy of Luxembourg had 238 service stations, of which 167 (almost three-quarters) were located in the immediate vicinity of the country's border. Luxembourg's relatively small surface area suggests that the service stations are all close to the border. However, there are disparities: in the interior of the country, the location of service stations depends for the most part on the geographical distribution of the population and the main transport network. The density of service stations is high in the region of Luxembourg City, the centre and main crossroads of the Grand Duchy where the A1, A3, A4 and A6 radial motorways converge, as well as in the densely populated areas of the south of the country, crossed from east to west by the A13. In the north of the country, however, where the population is lower and the transport infrastructure is still underdeveloped, there are fewer service stations. As the main road north of Ettelbruck is only a national road (N7), this region has no motorway access to neighbouring countries. [less ▲]

An urban microeconomic model of households evolving in a 2D cellular automata allows to simulate the growth of a metropolitan area where land is devoted to housing, road network and agricultural/green areas. This system is self-organised: based on individualistic decisions of economic agents who compete on the land market, the model generates a metropolitan area with houses, roads, and agriculture. Several simulation are performed. The results show strong similarities with physical Dieletric breakdown models (DBM). In particular, phase transitions in the urban morphology occur when a control parameter reaches critical values. Population density in our model and the electric potential in DBM play similar roles, which can explain these resemblances. [less ▲]

Calibration of households preference for open-spaces from an urban cellular automata model: method and application to Dijon

We propose a calibration method for a residential growth model that is grounded on a microeconomic cellular automaton. This model can be seen as a spatial and dynamic representation of an urban economic model with neighbourhood externalities. A 2D spatial equilibrium of residential locations is obtained stepwise through time instead of being a one-shot instantaneous equilibrium. Previous research work showed that the model can produce more or less dense and fragmented urban patterns depending on the preference of households for open space. We propose here a method for calibrating those preferences from simulations of the model and land rents observed within the Dijon urban area. More precisely, equilibrium properties of the model are used to derive the elasticity of open-space preferences. Then simulations are used to estimate the neighbourhood distance to which open-space are valued by households. Our first results tend to support our residential behaviour assumptions and tend to be in accordance with results obtained with more classic methods. Further methodological improvements are however needed. [less ▲]

Die Karte zeigt die Verbreitung der ehemaligen Steinkohlengruben der Großregion in der wallonischen und der saarländisch-lothringischen Lagerstätte von etwa 1800 bis heute. Nach der Schließung des letzten wallonischen Bergwerks Sainte Catherine du Roton 1984 und des letzten Lothringer Bergwerks La Houve 2004 endete 2012 mit der Stilllegung des Bergwerks Saar in Ensdorf der Steinkohlenbergbau in der Großregion SaarLorLux endgültig. Insgesamt wurden in den wallonischen Revieren über die Jahrhunderte rund 2 Mrd. t Kohle gefördert, im Saarland 1,5 Mrd. t und in Lothringen 800 Mio. t. [less ▲]

Coal mining plays a special role in the creation of the Greater Region. After the Second World War, the Schuman Plan, which provided for mutual control of the production of coal and steel (important products for the conduct of the war) and the maintenance of these production factors, which were indispensable for reconstruction, led in 1951 to the signing of the ECSC Treaty (European Coal and Steel Community), which constituted the first stage in the construction of the European Union. The "Saar-Lor-Lux" region drawn up in 1969 by Hubertus Rolshoven, Chairman and CEO of Saarbergwerke AG, was the "preliminary stage" of the Greater Region institutionalised in 1980; this mining region was integrated into the cross-border triangle of Saarland, Lorraine and Luxembourg.
