Claim 0:
1. A method for wayfinding in a hazardous environment, comprising:
receiving, at an emergency response computer program executed by an electronic device, a plurality of real-time streams of image data, each real-time stream of image data received from an image sensing device in an area;
detecting, by the emergency response computer program, an alarm condition out of a plurality of alarm conditions in the area based on the real-time streams of image data;
determining, by the emergency response computer program, that the alarm condition satisfies an alarm condition rule, wherein the alarm condition rule requires the alarm condition to exist for a predetermined period of time or to be present in more than one stream of image data;
calculating, by the emergency response computer program, a plurality of routes to an egress point from the area using a graph representing the area comprising a plurality of nodes and a plurality of edges connecting the nodes, wherein the nodes represent sub-areas within the area, and the edges represent paths between two of the nodes, and the edges are weighted based on a speed or flow between nodes from evacuation drill data; and
controlling, by the emergency response computer program, a digital signage in the area to display one of the plurality of routes to the egress point.
