📊 Project Overview

Comprehensive traffic analysis and sustainable mobility framework

Project Purpose

Transform an underutilized area into a vibrant, mixed-use district with robust transportation infrastructure. The project establishes a sustainable, resilient, and integrated mobility framework encompassing macro- and micro-modeling, detailed design, and analysis of various pedestrian and cycling loops.

📈 Key Recommendations

Strategic insights for sustainable mobility development

🚌

Prioritize Public Transport

Continue to prioritize and invest in public transport infrastructure, particularly dedicated bus lanes, to encourage mode shift and reduce private car dependency.

High Impact
⏱️

Optimize Signal Timing

Implement advanced signal timing optimization at key junctions (Hualing, Proposed Road, Kupradze) to improve traffic flow and reduce delays.

Medium Impact
🚴‍♂️

Enhance Active Mobility

Further develop and promote the bicycle network and cultural/natural loops to enhance active mobility options and improve quality of life.

High Impact
🔄

Adaptive Planning

Maintain an adaptive planning approach, regularly reviewing and updating traffic models and infrastructure plans based on actual development progress.
