Transportation infrastructure planning in supporting disaster mitigation: Case study in Mount Gamalama

Area of Science:

• Disaster Management
• Transportation Engineering
• Volcanology

Background:

• Ternate city, Indonesia, is disaster-prone due to Mount Gamalama, an active volcano, and its location on the Pacific Ring of Fire.
• Effective mitigation planning and transportation infrastructure are vital for community safety during volcanic eruptions.
• Existing infrastructure requires assessment to ensure adequate disaster evacuation routes.

Purpose of the Study:

• To formulate disaster mitigation measures for volcanic eruptions of Mount Gamalama.
• To identify and plan effective evacuation routes in this disaster-prone area.
• To analyze existing transportation network performance for disaster evacuation.

Main Methods:

• Quantitative approach utilizing transportation modeling with Vissim software.
• Road network observations and inventory surveys of land and sea transportation facilities.
• Analysis of existing traffic conditions and forecasting for evacuation scenarios.

Main Results:

• Ternate city's road network shows potential for use as evacuation routes.
• The existing road network demonstrates good performance regarding meeting and final evacuation points.
• Socialization of mitigation, clear signage, and prepared evacuation points are essential.

Conclusions:

• Local governments should develop new evacuation routes to enhance capacity in disaster-prone areas.
• Preparedness includes community awareness, clear signage, and well-defined evacuation points.
• Improving evacuation route capacity is critical for reducing casualties during volcanic events.
