Vulnerability Analysis of Fire Disaster Evacuation at old Thanjavur town, India using Space Syntax Method

Old towns of south India face difficulties to cope up with morphological changes due to rapid urbanization. This research understands the morphological configuration of old Thanjavur town based on three parameters: connectivity, integration and depth of street networks from the aspect of emergency evacuation in the event of a fire disaster.UCL DepthmapX simulation and Space Syntax are used to analyze the degree of connectivity and network. Analysis for regression between connectivity and integration shows correlation value of 0.2757 (R2=0.076) in western zone. The southern zone shows a correlation value of 0.3592 (R2=0.129). The correlation value of eastern zone is 0.3975 (R2=0.158) and in northern zone it is 0.2302 (R2=0.053). Result shows low levels of intelligibility in northern and western zones of Thanjavur town which are vulnerable in the event of fire disaster evacuation.
