Abstract

There are many cities on the west coast of the Sumatra, which are at high risk of the Tsunami disaster. Regional Regulations on Regional Spatial Planning for each City/ Regency have compiled disaster mitigation by constructing several evacuation roads. This study wants to illustrate: what are the volume of traffic generation and road performance, if there is a Tsunami disaster. The simulation is developed by predicting traffic volume based on parameters, population density, vehicle ownership, land use, and activities in the area around the road. The assessment was carried out on two tsunami evacuation roads in the city of Padang, West Sumatra Province. The results show that the highest traffic volume occurred in the period from 06.30 a.m until 3:00 p.m., during school activities. One of the roads will not be able to accommodate the volume of traffic during a disaster, due to significant traffic congestion. This study shows that: (1) the period of activity and land use are two main parameters, which must be considered in designing tsunami evacuation roads, (2) The degree of saturation ratio and the ratio between the capacity of sections of Tsunami evacuation routes can be proposed as a parameter for assessing the performance of Tsunami evacuation roads in urban areas.

Highlights

Law of the Republic of Indonesia number 24 of 2007, concerning Disaster Management, prioritizes handling based on the safety of human life [1]
Will a road designated as an evacuation route in a city be able to accommodate the volume of traffic that will pass through, and meet the standard criteria for evacuation routes? For this reason, an assessment of the evacuation road is required
Assumptions are influenced by several factors, including the catchment area, which is predicted to pass through the evacuation route during the tsunami, the number of population, motorized vehicle ownership, the age distribution of the population, and the number of family heads who live in the catchment area

Summary

Introduction

Law of the Republic of Indonesia number 24 of 2007, concerning Disaster Management, prioritizes handling based on the safety of human life [1]. Strategies in tsunami preparedness from various city governments in Indonesia focused on the following: developing an early warning system, planning an evacuation route, conducting evacuation drills, and raising local awareness [2]. Will a road designated as an evacuation route (horizontal evacuation route or street to a building on a vertical evacuation) in a city be able to accommodate the volume of traffic that will pass through, and meet the standard criteria for evacuation routes? One method that can be done is to simulate traffic volume prediction on the tsunami evacuation road section. Simulations can be done by considering the demand for evacuation movements that will occur on these roads. Various traffic flow scenarios that might occur due to land use and activity time in the catchment area (service area coverage) of the evacuation road are modeled
