Evacuation processes can be evaluated using different simulation models. However, recently, microscopic simulation models have become a more popular tool for this purpose. The objectives of this study are to model multiple evacuation scenarios and to compare the INTEGRATION microscopic traffic simulation model against the MATSim mesoscopic model. Given that the demand was the same for both models, the comparison was achieved based on three indicators: estimated evacuation time, average trip duration, and average trip distance. The results show that the estimated evacuation times in both models are close to each other since the Origin-Destination input file has a long tail distribution and so the majority of the evacuation time is associated when travelers evacuate and not the actual evacuation times. However, the evaluation also shows a considerable difference between the two models in the average trip duration. The average trip duration using INTEGRATION increases with increasing traffic demand levels and decreasing roadway capacity. On the other hand, the average trip duration using MATSim decreases with increasing traffic demand and decreasing the roadway capacity. Finally, the average trip distance values were significantly different in both models. The conclusion showed that the INTEGRATION model is more realistic than the MATSim model for evacuation purposes. The study concludes that despite the large execution times of a microscopic traffic simulation, the use of microsimulation is a worthwhile investment. / Master of Science / In recent decades, evacuation processes have become very valuable to protect people’s lives during disasters. Traffic engineers have developed different computer program tools to enhance the evacuation process. These tools can be categorized into three different groups: microscopic, macroscopic, and mesoscopic simulations. However, microscopic simulation tools have recently become more popular. The objectives of this thesis are to model multi-evacuation scenarios and to compare the INTEGRATION microscopic traffic simulation tool against the MATSim mesoscopic tool, given that the demand was the same for both tools. The demand describes the total number of vehicles that need to be evacuated. The tools were compared based on three indicators: estimated evacuation time, average trip duration, and average trip distance. The results show that, since the demand file has a large number of trips, the estimated evacuation times for both tools are similar. The average trip duration is generally computed by dividing the total travel time of all vehicles that need to finish their trips by the total number of vehicles. The results show that the average trip durations for the tools are different. The average trip duration using INTEGRATION increases with a decrease in the network capacity (number of vehicles within a specific distance). In contrast, the average trip duration using MATSim decreases with a decreasing network capacity. The average trip distance is computed by dividing the total travel distance by the total number of vehicles. The average trip distance values were significantly different for these tools. The results show that the INTEGRATION tool is more realistic than the MATSim tool and that it is able to capture the congestion effects in the network.
