In the heart of Iran, a young architect is challenging conventional urban planning wisdom, and her work could reshape how cities around the world approach street design and energy efficiency. Zahra Tahmasbnia, a master’s student at Shahrood University of Technology, has delved into the intricate web of social sustainable development, focusing on the transformative potential of the complete streets approach. Her research, published in the journal ‘توسعه پایدار شهری’ (Urban Sustainable Development), offers a fresh perspective on how streets can be more than just thoroughfares—they can be the lifeblood of communities, fostering social interaction and sustainability.
Tahmasbnia’s journey began with a simple yet profound question: How can urban streets contribute to social sustainability? Her answer lies in the complete streets approach, a design philosophy that prioritizes the needs of all users—pedestrians, cyclists, motorists, and public transit riders alike. “Streets are not just for cars,” Tahmasbnia asserts. “They are public spaces where social interactions happen, and they should be designed to encourage these interactions.”
To understand the impact of complete streets on social sustainability, Tahmasbnia employed the Scoping Review method, a qualitative research approach that allowed her to synthesize existing literature and identify key indicators. She found that these indicators can be grouped into four main categories: physical factors, safety and security, economic factors, and social and environmental factors.
Physical factors, such as street width, building height, and the presence of green spaces, play a crucial role in shaping social interactions. Safety and security, on the other hand, are about more than just crime prevention. They also encompass the psychological comfort of users, which can be influenced by factors like lighting, visibility, and the presence of other people.
Economic factors, such as the availability of jobs and services, can also impact social sustainability. Streets that support local businesses and provide employment opportunities can foster a sense of community and reduce social inequality.
Lastly, social and environmental factors, such as the presence of public art, cultural events, and environmental quality, can enrich the street experience and promote social interaction.
So, how might this research shape future developments in the field? For one, it underscores the importance of a holistic approach to street design. It’s not just about moving cars efficiently; it’s about creating spaces that support the social, economic, and environmental needs of communities.
For the energy sector, this research could have significant implications. Complete streets, with their emphasis on walking, cycling, and public transit, can reduce car dependency and lower greenhouse gas emissions. Moreover, streets designed with social sustainability in mind can encourage community engagement in energy-efficient practices, such as shared renewable energy projects.
Tahmasbnia’s work is a call to action for urban planners, policymakers, and energy sector professionals. It’s a reminder that our streets are more than just infrastructure—they are the stage upon which our cities’ social and environmental futures will be played out. And as Tahmasbnia puts it, “It’s time we start designing them with that in mind.”
