Thesis title: Visual Consonance in Townscape; Establishing a Psycho-Physical Model to Visually assess Townscape

Supervisors: Somwrita SARKAR , Peter ARMSTRONG

Thesis abstract:

The phenomenon of visual disorder is prominent in contemporary townscapes. The research provides a framework for the assessment of visual consistency in townscape in order to achieve more favourable outcomes for users. Visual consistency refers to the amount of similarity between adjacent components of townscape.The research investigates Parameters which relate to visual consistency in townscape, explores the relationships between them and highlight their most significant. The research uses arithmetic methods from outside the domain of urban design to enable the establishment of an objective method of assessment which considers subjective indicators including users’ preferences. These methods include the standard of deviation, colour distance and the distance between points. The research identifies urban space as a key representative of visual parameters of townscape. It focuses on its two components, geometry and colour, in the evaluation of visual consistency of townscape. Accordingly, it proposes four measurements. The first quantifies the number of vertices, which are points in the three-dimensional space that are connected by lines to represent the appearance of elements. The second evaluates the visual surroundings of urban space through assessing the location of their vertices. The last two measurements calculate the visual similarity in both vertices and colour in townscape by the calculation of their variation using methods including standard of deviation and colour difference. The proposed quantitative assessment is based on users’ preferences towards urban space ratio and the amount of similarity in both vertices and colour of virtual townscapes. The research offers a practical tool which can alter the current understanding of architectural form and its application in urban space. The proposed method underpins expert's subjective assessment and permits the establishment of a unified framework which adds to creativity by the achievement of a higher level of consistency and satisfaction among the citizens of evolving townscapes.
