Streets are not just channels for moving people and goods; they are the central public spaces through which a city functions, affects everyday life, and shapes the well-being of its residents. When streets are well-designed and integrated into the urban fabric, they support mobility, safety, social interaction, economic activity, and environmental sustainability. Conversely, poorly connected or underutilized streets can fragment neighborhoods, limit access to services, and reduce quality of life. Below is a concise synthesis of why city streets matter to both the functioning of a city and the people who live in it.

How streets enable city functioning

• Movement and circulation: Streets provide the physical space for the daily flow of people, goods, and services, enabling commerce, emergency access, and access to jobs and amenities. Efficient street networks reduce travel times and logistical frictions, boosting productivity.

• Connectivity and accessibility: A well-connected street grid links neighborhoods to workplaces, schools, transit, parks, and essential services, expanding opportunities and reducing isolation.

• Public space and place-making: Streets serve as the city’s largest public realm, hosting markets, parades, outdoor dining, street performances, and community gatherings, which sustain cultural life and local economies.

• Safety and social cohesion: Pedestrian-friendly streets with protected crossings, slower vehicle speeds, and good lighting improve safety for all users and encourage everyday social interaction, which strengthens community ties.

• Environmental benefits: Walkable, bike-friendly streets reduce dependence on cars, cut emissions, and support urban green infrastructure, contributing to healthier living environments.

How streets affect people’s lives

• Access to opportunity: People gain better access to jobs, education, healthcare, and services when streets form inclusive, legible networks, reducing social and economic exclusion.

• Health and well-being: Safe, walkable streets encourage physical activity, contribute to mental health through social interaction, and improve overall quality of life.

• Social life and equity: Street design that prioritizes pedestrians and diverse users fosters everyday encounters, strengthens local culture, and advances equity by ensuring that public spaces are accessible to all residents.

• Economic vitality: Vibrant streets with active frontages, street markets, and accessible public spaces support local businesses and can attract investment, tourism, and informal economies.

Key design and policy implications

• Multi-functionality: Streets should accommodate mobility, commerce, leisure, and civic life rather than serving a single purpose, enabling a more resilient and dynamic city.

• Connectivity and crossings: Adequate street connectivity and safe, frequent crossings improve accessibility and reduce social exclusion.

• Pedestrian emphasis: Prioritizing pedestrians and people on bikes over exclusive car movement enhances safety, health, and social interaction.

• Public space integration: Treat streets as public spaces where culture, policy, and daily life converge, not merely as traffic corridors.
