Real Time Evacuation Planning Model (RtePM)A Decision Support Tool for Emergency Managers and First RespondersPopulations can be distributed to particular endpoints by specifying a percentage of the population beingrouted to that endpoint. The aggregate percentage cannot exceed 100%. If no percentages are assigned,all endpoints are considered equal in the simulation.Removing Population BlocksPopulation blocks may be removed by selecting the “Remove” option as shown in Figure 22. Similar tothe “Add” button, population blocks may be deleted using either the freehand polygon, bounding box,circle or point option. After selecting the desired option, locate the shaded area on the map to be deleted.Once removed, the area will no longer be shaded. If an area is deleted by mistake, restore it using the“Add” option. All evacuation Zone data may be removed by selecting the waste can image to the left ofthe hand image or “Pan Mode” icon.Defining RoadsFigure 22 - Removing Population BlocksThe user has the option to add or remove roads and road networks when defining evacuation routes in aneffort to adequately portray varying scenarios. This is accomplished by selecting the “Roads” tab in theEvacuation Planning window. The “Roads” tab (Figure 23) has four sub tabs and are defined below.Figure 23 -- Defining Roads15
Real Time Evacuation Planning Model (RtePM)A Decision Support Tool for Emergency Managers and First Responders Selected Roads – potential pathways out of an evacuation zone. The RtePM programautomatically selects the most efficient pathways from the evacuation zone using NAVTEQ dataEvacuation Endpoints – points that denote safe destinations or distances from the evacuation zoneModified Roads – Contraflow, Shoulder Use and Road Closures (optional): these options are notpopulated by default, but allows planners and first responders to select highways that may beconfigured for Contraflow and Shoulder UseAdditional Roads – allows planners and first responders to define additional roadwaysTo add roads, use the “Add” button and select from the drop-down menu as shown in Figure 24Figure 24 -- Add Road ToolsThere are also four road options in the “Filters” window for describing road networks. These options canbe selected or deselected. By default, “Highway,” “Major Arterial,” and “Minor Arterial,” are preselected.“Smaller”, referring to non major roadways included in the evaucation area, can be added asneeded. In order to use filter check boxes, selections must be checked before defining roads. Filtering ofspecific roadways in the list view may be done using the button or by using the magnifying glassto select specific roadways for editing (Figure 25). To clear the filter click on the clear button.Figure 25 -- Road Filtering Options16
