| Summary: | Green Spaces along Linear Transport Infrastructures can provide services to the human society. It occurs through ecological processes that are taking place within these spaces. What are these services ? Is it possible and is there an interest in modifying these services ? The article is based on a concrete example. It offers a preliminary assessment of ecological services produced by natural habitats of these Infrastructures Green Spaces. Only regulation types of ecological services are likely to be present along Road and Rail Infrastructures. The article shows that there is a spatial variability of these services within these Green Spaces. It is highly dependent upon the landuse and to a lesser extent upon the surrounding environment. However, the study highlights the need for research to quantify the services produced on a local scale. The article then explores the factors that could modify the production of ecological services. Factors can vary based on management practices and maintenance, but also landscaping. It shows that new skills can be developed for a landscape design of ecosystem services. The anthropocentric approach of ecosystem services also considers that project managers can rely on actions promoting certain services for an eco-design of their infrastructure, better social acceptability and possibly an economic optimization of their project.
