This book explores the advantages of a linear model of planning in reducing regional
inequalities. Linear planning commonly discussed in the past as a method which plans the
development of the city is completely redefined here in the form of a design approach inspired
by projects shaped by linear routes such as cycle or walking paths. Such concept is applied to
the urgent topic of territorial marginality which specifically neglects rural and mountainous
areas and recently is coped by European and National policies. The analysis of these policies
demonstrates the necessity of alternative strategies equipped to deal with both the internal
and external causes that determine the critical conditions in these fragile environments. By
implementing the concept of linear planning in these contexts this book proposes to enlarge
the perspective of traditional policies contrasting the regional inequalities that usually
determine the design of projects just within the boundaries of the marginal areas. Cycle and
walking paths are experimental cases of linear planning as they have not been influenced or
formed by political boundaries and therefore are able to equally involve both the central and
marginal zones. This book presents a review of current issues such as regional inequalities
with attention to their related policies as well as an analysis of the concept of linear
planning as seen through the study of one of the most famous cases of a walking path-the Way of
St. James in Spain.
