Transformes - Cross Border Strategies For Integrating Land Use and Transport Development in the Strasbourg Region
G Wulfhorst, INSA de Strasbourg, FR
Land use and traffic are closely related to one-another. Passenger transport by moving between places for different activities is depending on the spatial structure of locations. Urban structures are evolving in correspondence to accessibility.
Intending the general objective of economic, ecologic and social sustainability, the urban region represents the perimeter to deal with.
Location development at multi-modal transport nodes is of particular interest: Links of different transport networks (roads, railways, airways, waterways) regularly generate a higher level of accessibility and interact strongly with their surrounding. In these places the development of urban forms and urban functions should therefore be handled with special care.
In the Strasbourg region, mobility can on the one hand be regarded as a basic condition for local quality of life. One the other hand improvements in accessibility could contribute to the strengthening of Strasbourg as European region. The challenge is to enhance existing regional potentials ? on a cross-border level.
OBJECTIVES According to these circumstances, further research for improving urban and transport
development on the regional level should concentrate on the following topics: - Effectiveness of structures: Which potentials exist, which measures can be taken, which effects can be expected in order to regain and foster functional and social mix, urban density, poly-centrality and proximity as basic conditions for sustainable transport development? - Efficiency of processes: How can the cooperation of stakeholders and actors (esp. of local authorities) as well as the processes of planning and realisation be improved in order to control regional and local development?
1. Basic investigations State-of-the-art German, French and international experiences in the relationship between transport supply, urban form, functional mix and mobility patterns are explored, collected and shared. Specific definitions and classifications of relevant terms (urban region, transport node, urban form/function) are realised.
Impacts and (more or less) successful processes can be observed and analysed from examples in the region of Strasbourg and other European regions. Existing studies and expert contacts of about 5 to 6 best practices can be used for verifying and refining hypothesis from the state-of-the-art analysis.
Key interactions and effects
As a synthesis, an interaction analysis will be carried out by a System Thinking approach. Both structure and process level are taken into account in a system of feedback mechanisms. The most important links and levers between land-use development and mobility are identified.
2. Case Study Conceptualisation in the European region of Strasbourg Structure analysis Structural change in urban development and transport development can be analysed relying on high quality investigations (like household surveys carried out in 1988, 1997 and 2004). From a perspective viewpoint, the major future changes in transport offer (like TGV Est, tram-train, etc.) will be reflected in their impact on regional location quality. Demographic development will be taken into account.
For analysing the underlying strategies, instruments, collective decisions and individual choices an analysis will be carried out based on the investigation of planning documents and expert interviews. As a framework for further strategies actual planning schemes will be considered, especially the ?Schéma de Cohérence Territoriale de la Region de Strasbourg (SCOTERS)? and the ?Livre blanc de la region transfrontalière Strasbourg-Ortenau? (INTERREG II).
Potentials and risks, scope of measures and effects
The ?Marges de Manoeuvre? will be identified by a scenario-based exploration on the regional level. First, potentials and related risks in urbanisation and transport supply are summed up on the regional level (map and text document). Then scenarios for possible developments will be worked out.
3. Measures and planning instruments
Regional master plan on location development at transport nodes A strategic planning document will be worked out exemplarily for the urban region of Strasbourg focussing on urban development at inter-modal transport nodes. Concepts and measures are defined on a framework scale for prospective development according to existing schemes (e.g. SCOTERS). For the transport nodes requirements in accessibility, intermodality, and integration of urban structures will be given. For urban development specifications are planned for the aspects of urban density, functional and social mix. This master plan could be worked out on a GIS-base and ?if feasible? accepted as common work base by the local authorities.
Exemplary demonstration of implementation in local planning processes
The regional master plan is the basis for implementing and testing measures and strategies in local planning processes. Urban and transport planning documents worked out at ADEUS give the opportunity to join, contribute to and observe a choice of these processes. About three sites will represent demonstrators for local evaluation of the regional strategy. Obstacles and synergies will serve as feedback for the regional master plan, for the general evaluation and recommendations.
4. Evaluation and Recommendations Effects of urban development on mobility and sustainability will be estimated. Especially the implementation of scientific findings in local planning processes will be a fruitful base for evaluating intra-regional cooperation strategies and appropriate planning tools. The findings will be summed up for the Strasbourg case study and in a general way. Conceptual recommendations and process strategies will be published and presented adequately.
The general objectives of the project should contribute to results on the following levels:
* knowledge: focussing on the effectiveness of structures (impacts of density, functional mix and design on mobility behaviour) and the efficiency of processes (cooperation and implementation tools) in order to achieve urban quality;
* practice: developing planning methodologies and implementing planning strategies (regional master plan, local implementation) based on scientific knowledge and experience on the practice level of the European Region of Strasbourg as case study;
* dissemination: transferring gained specific experience and knowledge on a general level and making them useful for other regions.
The project is based on existing studies like a project on the interaction between transport nodes and urban sites (Beckmann, Wulfhorst, Baier, Peter et al., 2003), a thesis work on station development (Wulfhorst 2003) an the French-German project Bahn.Ville (www.bahn-ville.net).
TRANSFORMES is funded by the European Commission within the Marie Curie Actions Program of the 6th Framework (http://europa.eu.int/mariecurie-actions). The project takes place from January 2004 to January 2006.
The project is conducted at INSA de Strasbourg (university, Pierre PELLEGRINO) and ADEUS (regional planning agency, Michel MESSELIS) by Gebhard WULFHORST. It is accompanied by a scientific panel of local and European experts.
