Comparison of the two Micro-Simulation Software AIMSUN & SUMO for Highway Traffic Modelling (Civil Project)

In order to make good decisions in transportation, decision-makers need some references to support the decision. One source for such reference is to perform a micro-simulation; a model for representing real-world conditions including the behavior of travelers, vehicles and the infrastructure.

This study will examine and present a comparison between AIMSUN (a commercial micro-simulation software) and SUMO (a non-commercial micro-simulation software), identifying advantages and disadvantages of these applications in relation to the study object Södra länken, that is E266 and E75, in south part of Stockholm, Sweden.

A calibration process is conducted in order to find the best value of a set of parameters in each software. The best set of parameters will be selected based on the lowest value of a Root Mean Square Error (RMSE) computed based on observed speed data and the model output. The parameters is then validated using evening peak-hour data.

This research gave result that from the given experiments with the SUMO software, the best set of parameters was when the value of Driver Imperfection at 0,3 and Driver’s Reaction Time at 1,7. For AIMSUN , the best set of parameters was when the value of Maximum Desired Speed at 100 km/h and Speed Acceptance at 1,1.

In comparison, AIMSUN has advantages in terms of the simplicity for the user in creating network, setting the parameters and creating animation over SUMO. The complexity of the SUMO software stimulate the user to carefully build the model.
