Real Time Evacuation Planning Model (RtePM)A Decision Support Tool for Emergency Managers and First RespondersConfiguration TabUsers can re-label the evacuation zone, redefine the color of the evacuation zone on the map, or editConfiguration Variables and Population Destinations (Figure 17).Figure 17 – Configuration Tab ScreenConfiguration Variables Population Change (%) - The percent the population has increased or decreased since thepopulation data was obtained. People/Vehicle – The average number of people in each vehicle during the evacuation. Vehicle Towing (%) – The percentage of vehicles which are towing boats, trailers, etc. (%) of Population Evacuating – The percentage of people who will be leaving the evacuation area.Population Destinations (%) of Evacuees to Shelters– The percentage of people who will evacuate to shelters. NOTE:RtePM users must ensure that the percentage of population going to shelters is less than the sheltercapacity. If this principle is violated, the simulation scenario will not complete and will give anerror message. (%) Using Private Vehicles - The percentage of people who will be leave the evacuation area viaprivate transportation. (%) Using Public Transit – The percentage of people who will be leave the evacuation area viapublic transportation. (%) As Pedestrians – The percentage of people who will be evacuating on foot.Additional configuration variables displayed in the “Configuration” windowTotal Population Total Population Evacuating Population Using Public TransitTotal Vehicles Total Evacuees to Shelters PedestriansTotal Vehicles TowingPopulation Using Private Vehicles11
Real Time Evacuation Planning Model (RtePM)A Decision Support Tool for Emergency Managers and First RespondersResponse TabThe Response window (Figure 18) allows users to set evacuation response parameters that help managethe volume of evacuees exiting affected zones. Under the “One Day” option, there are two types ofresponses, Standard (slow/medium/fast) and Custom. Standard response timing is a preset correspondingto the 11 (Slow), 8 (Medium) and 5 (Fast) hour response curves from the Army Corps of EngineersHurricane Evacuation Study. Custom timing is set using the Custom (Hours) field. Clicking the radiobutton next to "Custom (Hours)" allows you to select a custom response time from 1-24 hours.Additionally, users may want to define a Starting Hour. The Starting Hour defines how long into theevacuation people will wait before they start entering the road network. For example, if there are twozones, A and B, and A has a starting hour of 0 and B has a starting hour of 6, vehicles from zone A wouldstart entering the road network as soon as the evacuation started while vehicles from zone B would startentering the road network 6 hours after the evacuation started. This gives the planner the ability tostagger or phase evacuation zones.Figure 18 – Single Day Response ScreenResponse timing can also be defined over a period of days by selecting the Multi Day option (Figure 19).When choosing the Multi Day option, the following field must be defined:Day 1 Starting hour of evacuation on first day Ending hour of evacuation on first day Percentage leaving on first dayDay 2 Starting hour of evacuation on second day Ending hour of evacuation on second day Percentage leaving on second dayMulti Day response timing provides the planner with additional flexibility when executing scenarios.12
