Optimizing Tsunami Evacuation Routes in Padang City, Indonesia: A Transportation Infrastructure Resilience Approach

In light of the recurring tsunami threats faced by coastal cities, the significance of transportation infrastructure resilience is underscored, particularly in regions such as Padang City, Indonesia, which has previously experienced the devastating impacts of tsunamis, notably the Mentawai event. This study is aimed at developing a robust evacuation planning strategy to mitigate potential loss of life during tsunami occurrences. Through a quantitative analysis utilizing the PTV Visum software, optimal evacuation routes were identified, emphasizing the importance of infrastructure performance in emergency scenarios. The analysis revealed that certain road segments, including Jl. Raya Balai Baru 2, Jl. Mustika Raya, Jl. Rimbo Tarok - Belimbing, Jl. Koto Baru Banuaran, Jl. Thui Raya 2, Jl. Raya Gadut, and Jl. Durian Taruang, achieved a level of service A, indicating very good performance. These routes are essential for an effective evacuation plan, demonstrating superior efficiency and playing a pivotal role in disaster response strategies. The findings advocate for the integration of these optimal routes into urban planning and disaster preparedness initiatives, aiming to enhance the city’s resilience to tsunami threats. Recommendations are extended to the relevant authorities, highlighting the criticality of incorporating advanced transportation planning tools like PTV Visum in the development of evacuation strategies. Such measures are deemed instrumental in minimizing casualties during tsunami events, thereby contributing significantly to the safety and well-being of the populace.
