A Rigorous Definition of Axial Lines: Ridges on Isovist Fields

Title: A Rigorous Definition of Axial Lines: Ridges on Isovist Fields

Research Question: How can we develop a more accurate and efficient method for defining axial lines in urban landscapes?

Methodology:

1. Identify existing methods for defining axial lines, such as those by Hillier and Hanson (1984) and Benedikt (1979). 2. Propose a new method that combines local and global properties of space, eliminating the need for defining convex spaces and tracing connections between axial lines. 3. Develop an image processing technique for identifying lines from ridges in isovist fields.

Results:

1. Presented an algorithmic definition of axial lines inspired by local properties of space, which eliminates the need for defining convex spaces and tracing connections between axial lines. 2. Discussed current strengths and weaknesses of the method, including the potential for easy and effective implementation. 3. Showcased how the method can be applied to urban landscapes, providing insights into urban networks, navigation, and the propagation of epidemics.

Implications:

1. The new method offers a more accurate and efficient way to define axial lines in urban landscapes. 2. It provides valuable insights into the structure and function of complex urban networks, which can be applied to various fields such as transportation, social sciences, and crisis management. 3. The method opens up new avenues for research in urban morphology and complex systems, potentially leading to further advancements in the field.
