Pedestrian-friendly urban structures motivate people to use active modes of mobility and walk instead of using their car. Active mobility is associated with health-promoting benefits and assumed to support neighbourhood-based social interaction. In this context, walkability assessment tools help urban and transport planning to identify deficiencies for the walkability of urban neighbourhoods and use the results to work towards improvements. The results contribute towards the establishment of indicators to measure development and planning targets with respect to the walkability of urban neighbourhoods and continuous monitoring over time. Based on a newly developed and free available GIS-measurement tool this paper assesses the walkability of the 16 most populated Germany cities at a small scale. The lowest average walkability can be found in the city of Dortmund, while Frankfurt am Main shows the highest values. The paper discusses the methodology and the results for the 16 cities and uses short portrayals of the town planning history and pedestrian infrastructure in Dortmund and Frankfurt am Main to explain possible reasons for the differences in the measurement results.

This paper deals with the management of settlement growth in the Grand Duchy of Luxembourg from the perspective of informality. Luxembourg is subject to high demographic and economic growth pressures across all parts of the country (capital, old-industrialized South, rural North), which strongly challenges the current planning system. At the same time, there is no formal regional planning, apart from approaches of intermunicipal cooperation, which are mainly voluntary in nature. Drawing on empirical case studies in two high-growth municipalities (Junglinster, Schuttrange), the paper outlines planning decisions in the institutional triangle between municipality, state and private institutions. Informality serves here not only to compensate for a lack of planning control, but also to deal with the country's complex legal framework conditions. The vital interests of landowners come into play informally as well: since parts of the country's wealth emerge from the valorization of property, speculative interests are immanent, and thus block development processes. In this context, the paper addresses elements of a regional growth management that could close the gap that exists between state planning and municipal autonomy. [ABSTRACT FROM AUTHOR]

Ground-mounted photovoltaic systems have the potential to become one of the central elements of the coming energy system. The German federal government is now planning a significant and rapid expansion. However, the extent to which appropriate planning and measures take place in regions and municipalities will also depend on the spatial planning regulations of the federal and state governments. This paper explains that considerable support and control options are available to accompany expansion efforts. Cross-references to the Renewable Energy Sources Act and the Building Code are also shown and it is explained that the different types of ground-mounted photovoltaic systems may partially require a differentiated approach.

Small-scale, often polarizing changes in the population structure characterized by migration, have a crucial influence on the current development of settlements in Germany. Although state and regional planning tries to manage related demands for residential areas, competition for potential migration gains on themunicipal level often leads to an unregulated development of residential areas within the region. This paper therefore seeks to develop an approach for an inter-municipally coordinated planning of residential areas, which takes into account demographic developments, in order to reduce the overall land consumption. In a first step, the residential land requirements that can be derived from expected small-scale population movements are presented in the form of different scenarios for specific municipalities. In a second step, a screening approach is used to identify those municipalities that appear to be suitable for accommodating additional residential development land requirements on the basis of their amenities and accessibility. In a third step, the identified residential land requirements are assigned to test areas with the help of various indicators. The approach is illustrated using the example of the Halle-Leipzig region. [ABSTRACT FROM AUTHOR]

Due to increasing density-dependent competitions in land use, it is difficult to plan new industrial areas, especially for factories and businesses with a need for large-scaled sites. Economic interest groups demand to plan new industrial areas to keep the region in a competitive position. At the same time, many citizens and local politicians are concerned about new specific land use areas for industries. To locate suitable industrial sites in the catchment area of municipalities with land shortage and a high demand for space and to involve regional stakeholders into the planning process, new regional planning tools are required. The case study about the "Regionale Kooperationsstandorte" planning tool in this paper shows which additional values and challenges the recipients of the plan expect from the new planning approach. Apparently, the new regional planning tool is generally accepted by most of the stakeholders in the Ruhr Metropolis. But specific regulations and particular sites are highly controversial, due to diverging interests of different stakeholders and municipalities or due to changing circumstances, so that it is not possible to reach a consensus on all issues.

Strengthening inner urban development is a guiding principle of Germany's sustainability policy and the key to achieving the 30-hectare target. To date, however, it is hardly possible to determine retrospectively the share of building construction activity realized as inner and outer urban development. On the one hand, there is the genuine fuzziness of the inner urban area (Innenbereich) as a spatial construct, and on the other hand, there is the lack of available small-scale data on building construction activity. Against this background, this paper presents for the first time a methodological approach to determine and evaluate the relevance of inner urban development for large areas and over longer periods of time for Germany. The method is applied for the federal state of North Rhine- Westphalia and the housing construction activity from 1979 to 2011. The result shows a positive trend, indicating that cities and municipalities have succeeded in realizing more housing as inner urban development over time. At the same time, significant differences between urban and rural areas are apparent. A central conclusion is therefore to support smaller municipalities in their efforts for more inner urban development. [ABSTRACT FROM AUTHOR]

The paper analyses the municipal assessment practice for the selection of settlement areas in preparatory land-use planning displays the influence of research results on current planning practice. Based on an analysis of the state of research and the legal framework conditions, the assessment of potential settlement areas for 29 preparatory land-use plans has been analysed. As a result, it was determined that the number of selection criteria and the complexity of the assessment in planning practice has increased significantly in recent years. Furthermore, it became obvious that and towhat extend the planning methodology and the criteria applied to select settlement areas differ substantially between the municipalities. Despite extensive application-oriented research in recent years on the assessment and selection of settlement areas, only indirect influences of the research on planning practice can be identified. Nevertheless, the analyses revealed that municipality themselves also created new criteria and procedures. [ABSTRACT FROM AUTHOR]

Comparisons of cities are frequently used to evaluate urban transportation planning and policies. A typology of cities can contribute to adequately interpret the identified differences between cities. For this purpose, this paper collects 27 indicators of socio-economic characteristics, spatial structures, travel behaviour and the evaluation of local transport situation for 44 major German cities. We generate clusters of cities based on a factor and cluster analysis. The factor analysis identifies five latent variables called metropolitan character, bicycle-friendliness, affluence, influence of students, and private car orientation. The subsequent cluster analysis identifies five clusters. According to this typology, most cities that are considered good practices of urban transport policy in Germany belong either to the cluster of metropolitan cities or university cities with a cycling-friendly environment.
