This document discusses decision support systems and software that can be used to model evacuation demand and assist with transportation planning during emergencies. It describes several transportation modeling software packages that can be used to simulate demand through submodels of generation, departure time, distribution, modal split, and path choice. It also discusses the use of revealed preference and stated preference surveys to develop and calibrate demand models when real evacuation data is limited.

designed this system. In this paper, the real-time video transmission and computer technology are combined to
develop the monitoring equipment of the crowd, and constitute a stampede preventing monitoring and early
warning system with the quadrotor unmanned aerial vehicle (UAV) flight platform. Using a quadrotor UAV to
acquired video data, put the flow of people density real-time transmit to the background. The data compared
with the mathematical model of early warning that we make, early warning signal is automatically calculated.

Evacuation is characterized by rapid movement of people in unsafe locations or disaster sites to safer locations. The traffic management strategy for commonly used evacuations is the use of Shoulder-Lane, contraflowing traffic and gradual evacuation. Contra-flow has been commonly used in traffic management by changing traffic lanes during peak hours. To implement the contra-flow operation, there are two main problems that must be decided, namely optimal contraflow lane configuration problem (OCLCP) and optimal contraflow scheduling. Within the OCSP there are two approaches that can be used: zone scheduling and flow scheduling. Problem of contra flow and zone scheduling problem is basically an emergence evacuation route planning (EERP) issue. This research will discuss EERP with contraflow and zone scheduling which can guarantee the movement of people in disaster area to safe area in emergency situation.

Institution: Embry-Riddle Aeronautical University
Degree: Master of Science in Aeronautics
Year: 2020
This study will explore the Unmanned Aerial Vehicles (UAVs) have been increasingly used for providing humanitarian aid during natural disasters. This study will evaluate the effectiveness of the Northrop Grumman MQ-8B Fire Scout in providing humanitarian aid after natural disasters have occurred. The ability to utilize the MQ-8B will be analyzed by determining their ability to conduct humanitarian in areas affected by natural disasters and are largely inaccessible using the existing traditional methods. The viability of using UAVs in such operations in terms of abilities and costs will be compared to using response utility trucks. The study will determine the viability of using UAVs in responding to natural disasters while at the same time providing economic benefits. The use of UAVs will be compared to existing response approaches such as the use of emergency response utility vehicles and manned flight. The study will also develop a model to show the costs and benefits of utilizing MQ-8B in responding to natural disasters. A quantitative approach will be used to collect data from existing literature. Information will be obtained from various sources including the Insurance Information Institute, Federal Aviation Administration (FAA), National Center for Biotechnology Information (NCBI), Occupational Safety and Health Administration (OSHA), and the Transportation Research Board on UAVs and manned systems to help come up with a solution to these problems

Redistribution Problem of Relief Supply after a Disaster Occurrencecoreconferences
The great earthquakes have occurred in various places of Japan after an interval of several years. After the disaster occurred, it seems that some shelters have oversupplied relief commodities, others have lacked them. Since some survivors cannot stay at shelters for some private reasons, they must stay at their home even if the lifeline stops. This paper proposes a methodology to redistribute the oversupply at shelters and relief supply at local distribution center to the shelters and other locations such as elderly care homes lacked relief commodities around one week from the disaster occurrence as the planning horizon. From the computational results, regardless of the balance between total volume of relief oversupplied and total volume of relief lacked, our approach can find the locations with or without relief supply.

29. SP surveys allow us to simulate several emergency scenarios SP surveys must be designed, defining: Proposed scenarios must be realistic and clear, in order to limit distortions between real and stated behaviour.

38. Several commercial Decision Support Systems (DSS) are available to evaluate transport demand. Generally, these belong to the GIS (Geographic Information Systems) software class. GIS software integrates maps with their respective information or attributes. Through its ability to link spatial data (maps) and non-spatial data (attribute information) in one location, GIS provides a framework for efficient data storage and data retrieval, intuitive display of information in a spatial context, and combining various types of information so that the data may be analyzed further. Referring to demand model evaluation, GIS can be subdivided into two main classes: GENERIC GIS SOFTWARE TRASPORTATION GIS SOFTWARE SW AND DSS FOR DEMAND
39. GENERIC GIS SOFTWARE generic GIS software are developed and implemented in several fields (marketing, planning, business analysis, transport, and so on) Among the software belonging to the first class, we recall: MapInfo, a powerful Microsoft Windows-based mapping and geographic analysis application from experts in location intelligence. ArcInfo, the first GIS software available on the market SW AND DSS FOR DEMAND
40. generic GIS software are developed and implemented in several fields (marketing, planning, business analysis, transport, and so on) Among the software belonging to the first class, we recall: TRANSPORTATION GIS SOFTWARE OmniTRANS , which provides a versatile working environment for multimodal transport planning and modelling; it offers an integrated software platform for visual display of models and graphical presentation of results, strong project management tools to assist in managing all of the information associated with model scenarios. SW AND DSS FOR DEMAND
41. generic GIS software are developed and implemented in several fields (marketing, planning, business analysis, transport, and so on) Among the software belonging to the first class, we recall: Emme/2 , which is a graphical software tool for multimodal transportation planning, which allows the transportation network to be modelled and assigns the traffic generated under a given set of conditions TRANSPORTATION GIS SOFTWARE SW AND DSS FOR DEMAND

44. DSS belonging to the second class generally include comprehensive tools for: TRIP GENERATION TRIP DISTRIBUTION MODE SPLIT TRANSPORTATION GIS SOFTWARE SW AND DSS FOR DEMAND
45. DSS belonging to the second class generally include comprehensive tools for: The goal of trip generation is to estimate the number of trips, by purpose, that are produced or originate in each zone of a study area. Trip generation is performed by relating frequency of trips to the characteristics of the individuals, the zone and the transportation network. TRANSPORTATION GIS SOFTWARE TRIP GENERATION In some cases, there are two primary tools for modelling trip generation: Cross-Classification, which separates the population in an urban area into relatively homogeneous groups based on certain socio-economic characteristics; average trip production rates per household or individual are then empirically estimated for each classification; Regression Models, which allow evaluation and application of multivariable aggregate zonal models and disaggregate models at the household or individual level. SW AND DSS FOR DEMAND
46. DSS belonging to the second class generally include comprehensive tools for: Trip distribution models are used to predict the spatial pattern of trips or other flows between origins and destinations. DSS provide numerous tools with which to perform trip distribution, including procedures to implement growth factor methods, apply previously-calibrated gravity models, generate friction factors and calibrate new model parameters. TRANSPORTATION GIS SOFTWARE TRIP DISTRIBUTION SW AND DSS FOR DEMAND
47. Mode choice models are used to analyze and predict the choices that individuals or groups of individuals make in selecting the transportation modes that are used for particular types of trips. Typically, the goal is to predict the share or absolute number of trips made by mode. Software provides procedures for calibrating and applying mode choice models based on multinomial and nested logit models, and may be pursued at either a disaggregate or aggregate zonal level. Estimation of the parameters in the nested logit and multinomial logit model is performed by the method of maximum likelihood, which calculates the set of parameters that are most likely to have resulted in the choices observed in the data. DSS belonging to the second class generally include comprehensive tools for: Mode choice models are used to analyze and predict the choices that individuals or groups of individuals make in selecting the transportation modes that are used for particular types of trips.

71. MAXIMUM LIKELIHOOD In Maximum Likelihood estimation the value of the unknown parameters are obtained by maximising the probability of observing the choices made by a sample of users. LEAST SQUARES For given observed data, the least squares values of model unknowns are the values minimizing the sum of squared deviations, comparing the data to model predictions. A simple, important example is bivariate linear regression, where a straight line is fitted to n pairs of measurements on two variables, an independent variable and a dependent variable. III.

To follow the exercises approach, in literature, a set of methods to organise and to realise real experimentations are available For instance in USA, a set of procedures to implement evacuation exercises are developed.
In relation to these effects, several emergency scenarios can be defined.
RP surveys include preferences inferred from observations of a decision maker's actual choices, in relation to real contexts. SP surveys represent the stated behaviour of users in relation to hypothetical contexts. During evacuation trials, RP data can be obtained, even if they are affected by the laboratory effect, because each user participating in evacuation trials knows that he/she runs no real danger. Therefore, RP surveys during evacuation trials are a statement of behaviour in emergency conditions, similar to SP surveys with physical verification. SP surveys allow us to simulate several emergency scenarios, which can differ in user category, in the effect in space and time of the dangerous event. Proposed emergency scenarios must be characterized by the description of: period of reference; targets; effects produced in time and space. Possible distortions can be removed by comparing SP data with observed flows during evacuation trials.
