This study suggests a new spatial network model, called the space-connector model, for improving the representation of relations between spaces. Previous models have proved incapable of expressing the differences in the geometric and visual relations between spaces, such as the type and size of openings, the length of corridors, or the transparency of walls. New notations for explicitly representing these differences are proposed. This study suggests a modified process and map for calculating isovist, pedestrian route, based on the space-connector model. The space-connector model was implemented in the ‘ASpace’ tool and its functionality has been validated through an integrated analysis of space syntax and spatial properties as well as isovist and pedestrian route analysis.
