AI-DRIVEN INTEGRATION FOR DIGITAL CITIES
AI-Driven Integration of Smart Transportation and Landscape Design in Digital City Engineering
Bowen Sun
Traditional digital city projects often suffer from a functional silo, where transportation systems operate on static algorithms and landscape design follows empirical layouts, creating a disconnect that undermines overall urban livability. To bridge this gap, this study proposes a novel AI-driven integration framework. The approach establishes a unified spatiotemporal data pool, employs an LSTM network for traffic flow prediction enhanced by landscape context, utilizes a Random Forest model to generate and score landscape solutions, and introduces an attention mechanism to enable bidirectional interaction between the two domains. Experimental results demonstrate that the integrated AI model improves peak congestion response speed by 60%, reduces the prediction Mean Absolute Percentage Error (MAPE) to 8.5%, increases landscape-environment matching to 90%, lowers peak-hour congestion by 35%, and boosts resident satisfaction by 30%. This work provides a practical, data-driven pathway for developing more efficient, livable, and sustainable digital cities.

Case Study: Attention Mechanism for Peak Congestion
During morning peak hours near a central park, the AI model's attention mechanism prioritized landscape features like 'park entrances' and 'pedestrian cross-walk density', demonstrating its ability to identify the contextual landscape elements significantly influencing traffic patterns. Conversely, during off-peak hours, attention shifted to features like 'vegetation density' and 'bench availability', aligning with leisure utility. This highlights the framework's capability for dynamic, context-sensitive weighting to provide actionable insights for urban planners.
Key Takeaway: The attention mechanism provides context-sensitive insights, guiding interventions for specific traffic conditions and improving urban planning decisions.
