This study examines the impact of design modifications on pedestrian and vehicular traffic efficiency in Mananchira Square using Anylogic simulation software. Two scenarios were modeled: the existing layout with restricted entries and a proposed design without access controls. The proposed design includes repurposing public buildings, removing walls, and implementing new road networks. Simulations were run for 20 min, comparing pedestrian and vehicular movement patterns and travel times between various origins and destinations. Results indicate that the proposed design improves overall pedestrian movement efficiency by 22.7% and reduces average vehicular travel time by 22.2%. The number of vehicles traveling between destinations increased by 40%. Heat maps reveal more organic pedestrian movement patterns in the proposed scenario, suggesting a need for redesigning park layouts. The study demonstrates the utility of urban simulations in designing alternative public space configurations, highlighting improvements in accessibility and efficient use of space while identifying potential areas for further design considerations.
