New article published in IJAC

Hello everyone!
I’m excited to share that my latest research article is now published in the IJAC – International Journal of Architecture and Computing.

Overview#
The research formulates the DML method, shown in Figure 1, and uses it to examine how to improve connections by considering factors like green spaces, public transport access, and overall accessibility. A case study demonstrates how the method can create more connected urban transit systems based on TOD objectives. The main goal is to offer a fresh perspective on improving walkability and transit, especially in transit-oriented areas (TOD).
To apply the DML method, I use a case study of Jakarta’s Kalideres transit area, marked by the down arrow symbol (↓) in Figure 2, chosen for its relevance to the challenges faced by developing cities.

After running simulations and optimizations using the DML framework, which includes:
- Data gathering and agent-based modeling simulations,
- The shortest path algorithm for agent historical trails using the A-star algorithm,
- Geometric mesh and point simplification with Laplacian smoothing,
- NSGA-2 for multi-objective optimization to identify the best solutions among conflicting alternatives, and
- Clustering,
I found that walkability is critical and that the DML method can support TOD and sustainable development (see Figure 3). These findings align with current research on urban challenges and provide practical recommendations for cities facing similar issues. Improving walkability is a crucial step toward creating healthier, more livable cities.
