A context aware GIS strategy for last mile delivery in Ghana, using pickup and dropoff nodes and network isochrones instead of home to home routing.
# 📍 Accra PUDO Network Planning System
> A GIS-powered Pickup and Drop-off (PUDO) Network Planning Platform for Accra, Ghana.
---
## 📖 Project Overview
The **Accra PUDO Network Planning System** is a spatial decision support platform designed to optimize the placement of Pickup and Drop-off (PUDO) locations throughout Accra using Geographic Information Systems (GIS) and network analysis.
Unlike traditional approaches that rely on fixed-radius buffers, this project uses **walking-time isochrones** generated from the road network to determine realistic accessibility for residents.
The system identifies underserved areas, generates candidate PUDO locations, and evaluates them using spatial constraints such as:
- Road accessibility
- Walking distance
- Water bodies
- Flood-prone areas
- Gated communities
- Industrial zones
- Existing logistics infrastructure
---
# 🎯 Objectives
- Improve last-mile logistics planning
- Optimize PUDO placement
- Increase accessibility
- Reduce delivery costs
- Improve customer convenience
- Support data-driven urban logistics planning
