interACT: Redefining Urban Transit Design Through Social Architecture

Commuting in dense urban areas is often a solitary and stressful experience. In regions like Jabodetabek, Indonesia, where millions rely on public transportation daily, the challenges of overcrowding, lack of comfort, and minimal social interaction become evident. interACT addresses these urban mobility challenges by introducing a human-centered transit design rooted in social architecture. The project, designed by Chairunnnisa Luthfya, Danti Dewanti, and Ruth Amelia, received the Organizer's Choice Award in the @ease competition.

The Issue: Disconnection in Transit Spaces

Surveys conducted with commuters between the ages of 17–40 revealed significant dissatisfaction with commuting conditions. Over 45% of respondents pointed to inadequate facilities, while 64% expressed frustration with the lack of seating. Most commuters travel alone, which compounds feelings of isolation. The absence of meaningful interaction in these public spaces not only reduces comfort but also negatively impacts well-being.

Design Statement: Social Interaction + Comfort

The central goal of interACT is to reimagine public transportation spaces as hubs of social architecture, where interaction and comfort coexist. The design fosters both verbal and non-verbal engagement, encouraging individuals to connect while waiting, commuting, or transitioning between modes of transport. By creating micro-opportunities for human contact, interACT transforms transit into more than a means of mobility—it becomes a socially enriching experience.

Goals of the Project

The design approach emphasizes four core goals:

1. Happier Communities: Social connectivity reduces the risk of depression and fosters a sense of belonging.
2. Safer Environments: Interaction acts as a deterrent against crime, increasing perceived security.
3. Less Fatigue: Engaging socially during transit supports mental and physical well-being.
4. Healthier Lifestyles: Research shows that strong social networks contribute to longer, healthier lives.

Programme and Phases of Commuting

The interACT programme divides daily commuting into three key phases:

• Phase 1: Walking or cycling from home to the station.
• Phase 2: Waiting and traveling within the train system.
• Phase 3: Traveling from the station to the final destination.

By embedding design solutions at each stage, interACT ensures that the commuting journey is not only more comfortable but also socially engaging.

Design Solutions and Innovations

1. Walking (Mobility-Integrated Design): The interACT system attaches to backpacks, making it easy to carry while commuting.
2. Perching (Comfort in Waiting): A compact, foldable structure converts into a supportive seat while waiting at stations, easing fatigue.
3. Handle Extension (Shared Support): In crowded trains, interACT’s handles can be extended to allow others to hold on, turning the object into a tool for shared stability and spontaneous interaction.
4. Anti-Theft Adaptability: The integrated net secures belongings, addressing commuter safety concerns.

These solutions highlight interACT’s adaptability in different transit scenarios, ensuring practicality without sacrificing social or architectural value.

Social Architecture in Practice

interACT exemplifies how social architecture can be embedded into everyday commuting. The design recognizes that transit spaces are more than functional—they are social ecosystems. By prioritizing human comfort and interaction, interACT strengthens community ties, combats isolation, and enhances urban well-being.

In redefining how urban commuters experience public transit, interACT demonstrates the potential of design to transform mundane routines into moments of connection and comfort. By merging functionality with the principles of social architecture, this project showcases how innovative design can address not only physical needs but also emotional and social ones.

Through interACT, Chairunnnisa Luthfya, Danti Dewanti, and Ruth Amelia present a vision where commuting is no longer just about reaching a destination—it is about connecting, engaging, and thriving in the urban environment.
