Psyllidis's presentation on the rhythms of urban mobility and access focuses on how mobility patterns were altered during the COVID-19 pandemic. He begins by contrasting the drastic reduction in personal mobility with the sustained need for goods and services, leading to a shift where goods were delivered to people instead of them going out. This change highlighted the importance of access and connectivity, showing that while mobility decreased, the demand for access remained constant.
Psyllidis's team delved into the specifics of urban mobility during the pandemic, noting significant changes such as a 23% decrease in public transport use and an 8% increase in car use. Walking, in particular, saw a 59% increase as people sought to access nearby services and amenities. This shift underscored the inequality in access within cities, where some people had many amenities within walking distance, while others had few.
To address these issues, Psyllidis’s team developed tools to assess and improve urban mobility and access. One key tool was a dashboard analyzing the feasibility of maintaining social distancing on sidewalks. By examining sidewalk widths and the centrality of streets in Amsterdam, the team could identify areas where social distancing was difficult to maintain. This analysis showed that while some streets allowed easy social distancing, many did not, highlighting the challenges of dense urban environments.
Another significant development was the City Walk map tool, which measures the potential for social encounters and access to amenities within walking distances. This tool evaluates not just the number of accessible places but also the diversity of people who can access them. For example, it can show whether different age groups or socio-economic backgrounds are likely to use the same park or public space. This information is crucial for urban planning and public health, as it helps identify areas where people from different walks of life can come together, as well as potential hotspots for disease transmission.
Psyllidis emphasizes that understanding the spatial and social dynamics of urban environments is vital for creating resilient cities. The tools developed by his team provide insights into how urban spaces can facilitate or hinder social interactions and access to services. For instance, the analysis of potential social encounters can inform strategies to enhance social cohesion and mitigate the spread of infectious diseases.
In addition to these tools, Psyllidis discusses the broader implications of his research for urban planning. By integrating data on mobility, access, and social interactions, policymakers can better design cities that are inclusive and adaptable to changing circumstances. This approach aligns with the goal of creating cities that are not only efficient but also equitable, ensuring that all residents have access to essential services and opportunities for social interaction.
Psyllidis's research highlights the importance of a holistic view of urban mobility and access, considering both physical infrastructure and social dynamics. His team's innovative use of data and analytical tools provides a model for other cities looking to improve their resilience and inclusivity. By understanding and leveraging the rhythms of urban life, cities can better prepare for future challenges and create environments that support the well-being of all residents.
