Greenways as integrated systems: a proposal for planning and design guidelines based on case studies evaluation

Greenways (GWs) can play a key role in the context of policies and strategies for sustainable territorial development because they contribute to the development of integrated plans and interventions for environmental safeguarding and socio-economic growth. As is generally under-stood, in their modern conception, GWs are not only develop soft mobility, but they also represent supporting elements of a new concept of development and use of territory, attentive to its particular characteristics and the needs of resident populations. Beginning with a critical analysis of the most significant case studies of greenways, the authors propose a system of design and evaluation guidelines useful in identifying specific GW-related actions. The identified actions are divided into two categories, which are tangible and intangible actions. The first category corresponds with concrete actions that are directly implemented through different design and construction phases; the second category corresponds with processes activated in the design phase and are concretized after the “commissioning” of the path and has repercussions on the sphere of place identity. These categories are often difficult to distinguish between because many actions can be considered to be both tangible and intangible.
