Investigating the role of spatial configuration on pedestrian movement behaviour in commercial streets

This thesis investigates how spatial configuration influences pedestrian movement behaviour within the commercial streets of low-density urban centres, focusing on Toowoomba, Australia, as a case study. Low-density cities often face challenges such as dispersed urban forms and car-centric infrastructure, hindering walkability and urban vibrancy. This study addresses these issues by reviewing walkability practices, analysing the impact of spatial configuration on pedestrian behaviour, and exploring the role of spatial cognition in walkability experiences. Adopting a mixed-methods approach, the research integrates quantitative spatial metrics with qualitative insights. A systematic review using PRISMA guidelines identified a critical gap in integrating Space Syntax with other methodologies to study socio-spatial relations in low-density city centres. To address this, the study combined Space Syntax analysis with observational techniques, GPS tracking, ArcGIS and semistructured interviews, specifically focusing on city centres in low-density urban areas. Axial maps assessed spatial integration, connectivity, and intelligibility, while qualitative methods captured pedestrian experiences and perceptions. The findings highlight that connectivity alone does not dictate pedestrian activity; rather, a combination of land-use mapping and spatial configuration within localised areas is a key factor. Strategically placed land uses enhance pedestrian flow during the day (1– 3 PM), while nighttime activity (6–8 PM) requires a balance between connectivity and preferred land uses. This study emphasises the need to align urban design with pedestrians' spatial cognition, behavioural patterns and perceptions. Strategies like accessible pathways, improved wayfinding systems, and enhanced lighting are essential to fostering pedestrian engagement and creating vibrant, sustainable, lowdensity urban city centres.
