Chapter III: Project Design Details

A. Conceptual Framework

The project design follows a systematic approach integrating Geographic Information Systems (GIS) and risk assessment methodologies to optimize evacuation center route planning. The framework involves analyzing hazard data, assessing infrastructure, and simulating evacuation scenarios to enhance disaster preparedness. The study aligns with global best practices in emergency management and local government disaster risk reduction policies.

The conceptual framework is structured as follows:

1. Hazard Mapping – Identifying flood-prone areas using historical data and GIS modeling.

2. Infrastructure Assessment – Evaluating road networks and evacuation center facilities.

3. Route Optimization – Using GIS-based algorithms to determine the most effective evacuation paths.

4. Simulation and Validation – Testing route feasibility under simulated flood conditions.

5. Implementation Strategy – Coordinating with local authorities for integration into disaster response plans.

B. Workflow Process

The workflow process ensures systematic data collection, analysis, and decision-making in the development of an optimized evacuation route plan:

1. Data Collection – Gathering spatial data on flood hazards, population distribution, and road networks.

2. GIS Mapping – Processing and analyzing geospatial data to visualize risk zones and infrastructure constraints.

3. Route Selection – Identifying primary and secondary evacuation routes based on shortest-path analysis and safety considerations.

4. Stakeholder Consultation – Engaging local government units (LGUs), emergency response teams, and community representatives.

5. Testing and Validation – Simulating evacuation scenarios and refining routes as needed.

6. Finalization and Dissemination – Integrating the optimized routes into official emergency response plans and public awareness campaigns.

C. Program

A structured program ensures that each phase of the project is executed efficiently and aligned with disaster risk reduction goals. The program consists of the following key activities:

Phase 1: Data Acquisition and Hazard Mapping

• Compilation of flood risk maps and historical disaster records.

• Identification of critical infrastructure and transportation networks.

Phase 2: Infrastructure and Route Assessment

• On-site validation of road conditions and potential bottlenecks.

• Analysis of alternative routes and accessibility of Barangay Poblacion E’s evacuation center.

Phase 3: GIS-Based Route Optimization

• Implementation of shortest-path and network analysis algorithms.

• Integration of multi-criteria decision-making (MCDM) techniques for risk-based route selection.

Phase 4: Stakeholder Engagement and Validation

• Conducting workshops with LGUs, MDRRMO, and community leaders.

• Field testing of proposed evacuation routes during simulation exercises.

Phase 5: Implementation and Policy Integration

• Formal adoption of the optimized evacuation route plan.

• Capacity-building initiatives for disaster responders and the local community.

D. Project Design

The project design encompasses both technical and operational considerations for ensuring an efficient evacuation strategy. Key design elements include:

1. GIS-Based Risk Analysis

Utilizing GIS tools to overlay flood risk data with population density and road infrastructure, ensuring routes avoid high-risk areas while remaining accessible.

2. Evacuation Route Classification

Categorizing evacuation routes based on:

• Primary Routes – Main roads with high capacity and accessibility.

• Secondary Routes – Alternative paths in case of obstructions.

• Tertiary Routes – Footpaths and community-based evacuation pathways.

3. Accessibility Considerations

Ensuring routes are suitable for all evacuees, including:

• Elderly and persons with disabilities (PWDs).

• Households with limited mobility.

• Emergency vehicle access and response time optimization.

4. Digital Mapping and Real-Time Monitoring

Developing digital maps that integrate real-time hazard data, ensuring continuous route assessment and updates.
