Context-sensitive urban development initiatives: an investigation on mobility and accessibility on main street urban stretch, Ambalangoda and its impact on public life

Abstract

Ambalangoda, a coastal township in the Southern Province of Sri Lanka, is known for its cultural heritage of mask-making and puppetry but faces uncoordinated urban growth that has fragmented its spatial fabric. The historic main street, once a vibrant social and commercial corridor, now struggles with congestion, poor pedestrian infrastructure, and declining urban quality. This research investigates the socio-cultural and spatial evolution of the Ambalangoda Main Street, examining its potential as a catalyst for context-sensitive urban transformation. The study explores how mobility patterns and accessibility infrastructure shape collective urban experience while balancing heritage preservation with inclusive growth. Methods included spatial mapping, behavioural observations, stakeholder interviews, and historical analysis. Mobility assessments and pedestrian movement studies were supported by photographic documentation and GIS-based mapping, while community engagement sessions captured the aspirations of residents and traders. Findings highlight critical challenges in traffic management, fragmented connectivity, and underutilized cultural assets. The paper proposes urban design strategies to enhance mobility, prioritize pedestrians, improve streetscapes, and integrate cultural nodes within the mobility network. These interventions aim to revitalize public life, foster sustainable tourism, and strengthen socioeconomic resilience by placing the community at the centre of future development.
