City Transport Transparency Tool

The City Transport Transparency Tool (CTTT) offers city planners and administrators the capability to develop evidence-based, sustainable mobility strategies that address the interconnected challenges of rapid urbanization, climate change, and social equity.

This comprehensive planning platform integrates transport analysis with housing, economic development, and environmental considerations to enable holistic urban transformation.

The CTTT embraces the complex relationships between mobility, urban form, and socio-economic development.

This integrated methodology enables cities to:

• Quantify Hidden Potentials: Reveal suppressed travel demand, particularly among women and marginalized communities, transforming transport planning from a reactive to proactive discipline
• Model Complex Interactions: Capture feedback loops between transport investments, land values, housing affordability, and economic productivity
• Evaluate Impacts: Assess not just traffic flows but comprehensive outcomes including emissions, public health, economic benefits, and social equity
• Compare Future Pathways: Explore multiple scenarios from incremental improvements to transformative change, understanding trade-offs and synergies

The tool employs simple and accessible methodologies grounded in peer-reviewed research, which incorporate considerations on population and housing integration; gender-differentiated analysis; multi-modal assessment; environmental accounting; economic valuation.

The tool’s scenario framework enables systematic exploration of alternative urban futures, including current baselines, business as usual scenarios, enhanced development, avoid strategies, and shift strategies. Each scenario generates comprehensive outputs across environmental, economic, and social dimensions, enabling multi-criteria decision-making aligned with local priorities and global commitments.

The CTTT is:

• Accessible for all cities: Designed for use by planning departments with varying technical capacities, the tool provides intuitive interfaces while maintaining analytical rigor.
• Scalable: Applicable from neighborhood-level interventions to metropolitan-wide strategies, accommodating cities from 100,000 to 20 million residents.
• Context Sensitive: Incorporates GDP-responsive parameters that adjust for local economic conditions, ensuring relevance across development stages.
• Comprehensive: Generates actionable metrics including modal splits, emission trajectories, congestion levels, economic returns, and equity indicators.
• Evidence-Based: Translates complex calculations into clear visualizations and policy recommendations that facilitate stakeholder communication.
