A series of disasters, from the 2004 Aceh Tsunami to the 2009 Padang Earthquake, has changed the paradigm of urban development in coastal areas in Indonesia. District or City Regional Regulations concerning Regional Spatial Planning finally oblige disaster mitigation by constructing evacuation roads. The attraction of the Tsunami Evacuation Road (TES) which was built with a relatively wide size in the city, makes the road a favourite route for motorists. The increased vehicular traffic also triggered the addition of the number of new commercial buildings along the road. The Indonesian Road Capacity Manual 1997 for urban roads is used as a reference in the analysis of the service performance of these road sections. The relatively rapid increase in traffic volume and side-road disturbances have resulted in a relative decline in road performance in a short period. The active role of the government in minimizing body side disturbances, by maximizing the implementation of traffic management and control of land-use changes are options.
