Building on previous research, we introduce a traffic simulation platform enhanced for real-world urban planning. By optimizing large-scale data processing and interactions, we demonstrate technical maturity as a practical decision-support tool, moving beyond visualization toward immediate, high-performance deployment in professional and production-ready environments.
Based on the 2D/3D visualization and scenario editing workflows established in previous years, the third year focuses on securing PERFORMANCE EXCELLENCE and OPERATIONAL EFFICIENCY required for professional environments.
[Key Advancements]
• WebGL-based High-Performance Engine and State Management Optimization
: Optimized the WebGL rendering engine to process large-scale traffic networks and high-precision terrain data without latency. Designed a sophisticated State Management structure between Cesium and OpenLayers to ensure stable operation.
• User-Centric Interaction Enhancement
: Developed an interface to precisely control complex road structures, such as overpasses and underpasses. Improved UX to reflect professional workflows, increasing the convenience of simulation settings.
• Flexible Data Compatibility
: Strengthened Import/Export functionalities for seamless integration with external simulation engines and various GIS data formats, maximizing scalability and practical data utility.
• Analytical Reporting System
: Added a dashboard-based reporting feature to provide intuitive insights. This allows analytical data to be immediately utilized as evidence for urban policy-making.
Technical Stack & Standards
