Agent-based model in GAMA simulating urban mobility scenarios using GIS and GTFS mobility data in Freetown, Sierra Leone. # Freetown-mobility-gama Development for an agent-based model pilot study in GAMA simulating urban mobility scenarios using GIS and General Transit Feed Specification (GTFS) mobility data in Freetown, Sierra Leone. **Overview** This project develops a pilot pedestrian mobility simulation for Freetown’s Central Business District (CBD) using GIS data and the GAMA agent-based modeling platform. It is designed as a decision-support tool to help municipal planners evaluate how transit expansion (including a proposed cable car by the City), housing densification, and commuter growth may impact pedestrian movement through 2028. The model simulates daily pedestrian flows across different times of day, identifies streets likely to experience increased pedestrian pressure, and supports scenario testing under data and budget constraints typical of resource-limited cities. The pilot study focuses on the mobility behavior of professional workers, including those who both live and work in the CBD and those who commute into the CBD from designated origin–destination pairs linking residential areas, office locations, and transit nodes. **Purpose** The tool helps planners: -Compare current and future pedestrian congestion patterns -Identify streets suitable for pedestrianization or traffic calming -Explore impacts of cable car adoption, densification, and commuter growth -Support evidence-based planning with limited data availability (Above: Pedestrian Mobility Impact & Planning Decision Support Tool User-Interace Pilot) (Above: GAMA Project Model Pedestrian Mobility Simulation) The model identifies streets in Freetown’s CBD likely to experience sustained and intensified pedestrian activity, highlighting corridors that may benefit from pedestrianization, traffic calming, or road space reallocation. This focus is particularly relevant in Freetown, where pedestrian congestion often overlaps with informal street vending on vehicle-oriented roads, creating mobility constr …
