A method for determining and displaying at least one least water logging prone route, from a source location to a destination location specified by a user, during a water logging condition in an area, comprising: a) receiving, by at least one processor inside a fusion server, GPS location information obtained from at least one position sensor embedded in a portable communication device, wherein the GPS location information comprises coordinates of a source location and a destination location; and determining at least two routes from the source location to the destination location by the portable communication device; b) receiving, by the fusion server, rainfall information captured from a plurality of dynamic weather sensors placed in the environment; determining at least one alternate route, from the at least two routes, from the source location to the destination location; characterized in that it further comprises: c) determining, by the fusion server, confidence matrices for all the routes starting from the source location of the user to the destination location, wherein the confidence matrices include confidence scores for the routes and the confidence scores are used to calculate a real time water logging index for each route, wherein the confidence matrices for a route are determined based on: i) the severity of water logging in a hot spot area on the route, wherein the hot spot area indicates an area which is prone to water logging, and wherein the severity of the water logging is indicative of how prone the hot spot area on the route is to water logging, ii) the rainfall information from the plurality of dynamic weather sensors, iii) a plurality of votes received from people based on their previous experiences related to water-logging, and iv) historical statistics of a plurality of known water logging prone areas on the route; and d) displaying, by a display module in the fusion server, on the portable communication device, an aggregate water logging index calculated from the real time water logging indices for the routes; and suggesting a best route to the destination location. a) receiving, by at least one processor inside a fusion server, GPS location information obtained from at least one position sensor embedded in a portable communication device, wherein the GPS location information comprises coordinates of a source location and a destination location; and determining at least two routes from the source location to the destination location by the portable communication device; b) receiving, by the fusion server, rainfall information captured from a plurality of dynamic weather sensors placed in the environment; determining at least one alternate route, from the at least two routes, from the source location to the destination location; c) determining, by the fusion server, confidence matrices for all the routes starting from the source location of the user to the destination location, wherein the confidence matrices include confidence scores for the routes and the confidence scores are used to calculate a real time water logging index for each route, wherein the confidence matrices for a route are determined based on: i) the severity of water logging in a hot spot area on the route, wherein the hot spot area indicates an area which is prone to water logging, and wherein the severity of the water logging is indicative of how prone the hot spot area on the route is to water logging, ii) the rainfall information from the plurality of dynamic weather sensors, iii) a plurality of votes received from people based on their previous experiences related to water-logging, and iv) historical statistics of a plurality of known water logging prone areas on the route; and i) the severity of water logging in a hot spot area on the route, wherein the hot spot area indicates an area which is prone to water logging, and wherein the severity of the water logging is indicative of how prone the hot spot area on the route is to water logging, ii) the rainfall information from the plurality of dynamic weather sensors, iii) a plurality of votes received from people based on their previous experiences related to water-logging, and iv) historical statistics of a plurality of known water logging prone areas on the route; and d) displaying, by a display module in the fusion server, on the portable communication device, an aggregate water logging index calculated from the real time water logging indices for the routes; and suggesting a best route to the destination location.
