Stakeholders’ perception of sound in Transit-Oriented Developments (TODs)

Yildirim, Yalcin / Arefi, Mahyar

Highlights • The heterodox view exists among TOD stakeholders for sound. • TODs, particularly mixed-land use, affect sound perceptions. • TODs include various sound potentials on policy/planning/design approaches. • The sound should be considered in pre-development, during development, and post-development phases.

Abstract With various possibilities associated with their planning and design from walkable pockets to ample public spaces for different socio-demographic cohorts, Transit-Oriented Developments (TODs) claim to improve their residents’ quality-of-life (QoL). Having been explored from various aspects, very few studies have explored their sound implications, particularly when they reflect transportation and planning impacts. This paper explores the sound policy considerations of transportation experts and local officials, what their designers have envisioned, and the sound perceptions of TOD residents. Using in-depth interviews with policy experts, designers, and residents, this study adopted a qualitative approach. Some unorthodox findings between the residents’ perceptions and designers’ visions as well as policy experts’ attitudes toward sound emerged. While policy experts regulate and designers designate various sound sources to promote urban life in TODs, in addition to receiving these sounds, residents perceive higher sound level sources i.e., traffic. This observed discrepancy adds a different lens into transportation practice and policy that requires appropriate attention among the said stakeholders.
