Abstract
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.
