The document discusses the economic benefits of improving streets and public spaces to prioritize pedestrians over cars. It notes that increased foot traffic on high streets from better walking environments can boost retail sales by up to 30%. Examples are given of cities where reallocating street space to walking and public transportation led to increased footfall and economic activity. The conclusion emphasizes that a focus on people and place quality is critical for local economies, and restricting polluting vehicles is important since poor air quality deters human activity and spending. Better data is still needed to understand these relationships fully to guide policy changes.
