Abstract:

Earthquakes can significantly disrupt societal functioning, infrastructure damage, and lead to loss of human lives and property, warranting a coordinated and efficient response to lessen the adverse impacts. The diversity of the users makes it very difficult for the post disaster response and recovery operations. During the past earthquakes 1995 kobe, 1999 Turkey, 2001 Bhuj and quite recent, 2011 Tohoku the damages to road transport systems was predominant. For the planning of disaster response operations, the vulnerability of road network is crucial and it affects the response time. This paper addresses the critical route transport network afthe there is an earthquake disaster in the city of Vijayawada (IS 1893-2003) with a potential of causing liquefaction. The study mainly focuses on the disruption of major roads and highway connecting the city considering, liquefaction hazard, approachability to hospitals and population density distribution of the city. The paper analyzes different road paths in the city using edge weight estimation method in which weights are assigned to the different factors considered. Different paths for the evacuation were proposed. The results are advantageous for further study of the evacuation were proposed. The results are advantageous for further study of the economic impact of highway damage during earthquakes.
