This visibility analysis model was developed in the Rhinoceros and Grasshopper software environments and is based on the conceptual model presented in Fisher-Gewirtzman (2016): a 3D Line of Sight (LOS) visibility analysis, taking into account the integrated effect of the 3D geometry of the environment and the variant elements of the view (such as the sky, trees and vegetation, buildings and building types, roads, water etc.). In this paper, the current advancement of the existing model considers the visual perception of human users employing three types of movement in the urban environment--pedestrians, cyclists and drivers--is explored.We expect this research project to exemplify the contribution of such a quantification and evaluation model to evaluating existing urban structures, and for supporting future human perception-based urban design processes.

These means of trans- portation would contribute to good urbanity. While the car still remains the main transportation solution in many cities, “ecological” transportation solutions are increasingly adopted to reduce the dependence on cars. To encourage pedestrian and cyclist trans- portation, proper routes, that provide not just essen- tial attributes such as safety but also special experien- tial perceptions, should be developed through plan- ning and design decisions.
