Review on Measuring Human Mobility Diversity

Human mobility diversity refers to the variety of movement patterns in urban settings, which are crucial for addressing urban challenges like traffic congestion and social equity. This literature review synthesizes 212 studies from 1903 to 2025 across multiple disciplines, examining the evolution of human mobility diversity research from its origins in traffic engineering to its current data-driven methods. It categorizes measurement approaches into individual-based indicators (e.g., Mobility Entropy using GPS data) and location-based indicators (e.g., Flow Gravity Index using census data). The review highlights the practical implications for urban planning strategies that aim at sustainability and equity. It identifies emerging trends such as data-driven analysis, interdisciplinary research, and a focus on equity. Gaps noted include the lack of standardized metrics for assessing multimodal mobility equity and ethical concerns regarding data privacy. Future research should focus on developing enhanced metrics (e.g., weather-adjusted), promoting interdisciplinary integration through advanced analytical techniques, and ensuring global coverage to address biases and enhance generalizability.
