Abstract
This study examines two crucial interlinked physical planning and design aspects with potential impact on pedestrian flow in urban settings. Mixed land uses and gridded/interconnected streets are invariably characterised in the urban design literature as the essence of vibrant cities and lively street environments. The study develops a critical approach that investigates some of the most popular algorithms utilised in assessing mixed-use characteristics and their impact on pedestrian movement. “Entropy,” “LUM,” and “dissimilarity” indices are critically evaluated in terms of their reliability in predicting pedestrian travel patterns. The study also examines street network measurement indices and spatial analysis tools that enhance urban vitality and aid in the design and development of active street environments. It bridges the gap between disparate approaches aiming at understanding and prescribing the built environment attributes that enhance urban vitality. The theoretical quest of this study provides a robust foundation for future case study research on the built environment.
