Urban Pulse: Capturing the Rhythm of Cities

Area of Science:

• Urban studies
• Data science
• Computational social science

Background:

• Cities exhibit dynamic patterns across multiple spatial and temporal scales.
• Existing data analysis methods often overlook the dynamic nature of urban environments.
• Technological advancements provide vast urban datasets for study.

Purpose of the Study:

• To develop a novel approach for understanding cities within the context of multiple urban datasets.
• To introduce and define the concept of an "urban pulse" for capturing spatio-temporal activity.
• To create a framework for exploring and comparing urban dynamics.

Main Methods:

• Defined "urban pulse" to represent spatio-temporal activity across various temporal resolutions.
• Utilized data topology to identify prominent pulses and characterized them as "beats".
• Developed a visual exploration framework for analyzing pulses within and across cities.

Main Results:

• Demonstrated the ability to capture dynamic urban activity using the "urban pulse" concept.
• Enabled analysis and comparison of different urban pulses based on their constituent beats.
• Showcased the framework's utility through three expert-led case studies.

Conclusions:

• The "urban pulse" offers a new lens for analyzing urban dynamics from diverse datasets.
• The visual exploration framework facilitates deeper insights into city activity and comparisons.
• This approach has practical applications for urban planning and behavioral science.
