Workshop #4 Capturing Walkability

Application of Convex and Solid Voids in open public space analysis

Dates: 4-6 July

ECTS credits: 1,5

Duration: 2,5 days

Number of contact hours: 21

Maximum number of participants: 15

*The title of this workshop appears as “Classification and Analysis of Open Urban Spaces” on the registration form.


  • To acquire a general understanding of means to quantitatively analyse the aspects of the built environment of open urban spaces that affect the quality of urban experience.
  • To learn about the Convex and Solid Void representation model, the theory behind it, its capabilities to classify and assess urban open spaces. To understand the potentials and possible future uses of this model.
  • To get a command of Convex and Solid Voids as well as some other 3d model and GIS based methods to analyse urban streets for walkability.
  • To map, analyse and understand the data acquired for each unit of urban space and compare with data from other sources indicating urban activity.
  • To apply acquired analysis methods on a defined area within a selected neighborhood.


A brief overview of walkability as a quality of the built urban environment and morphological attributes contributing to it will be presented. The theory and application of a 3d representational and analytical model of open urban spaces – the Convex Solids and Voids – as well as some additional automated methods to classify and analyse urban streets will be introduced. The use of these methods in assessing walkability of urban streets and mapping, basic analysis and understanding of acquired data will be explored. A study of an urban area in Lisbon will be carried out with the participants as a case.


Basic command of Microsoft Excel, Rhinoceros3d, Grasshopper and GIS (QGIS or ArcGIS) software is required.

Python scripting language knowledge is a plus.


July 4 (afternoon):

  • General introduction to quantitative assessment of urban environment qualities and walkability. Basic introduction of software to be used.

July 5 (whole day):

  • Lecture introducing the Convex and Solid Voids model, it’s theory, current and future applications. Demonstration of a case study.
  • Application of Convex and Solid Voids model on a selected case.

July 6 (whole day):

  • Introduction of additional methods of calculating indicators in 3d model and GIS.
  • Mapping and analyzing of resulting data. Presentation of other potential uses of introduced methods.

If there is no quorum, the workshops will be cancelled.
