An interactive tool is developed for the purpose of rapid exploration ofdiverse traffic scenario. The focus is on rapidity of design and evaluation rather thenon physical realism. Core aspects are the ability to define the essential elements fora traffic scenario such as a road network and vehicles. Cubic Bezier curves are usedto design the roads and vehicle trajectory. A prediction algorithm is used to visualizevehicle future poses and collisions and thus provide means for evaluation of saidscenario. Such a program was created using C++ with the help of Qt libraries.

Today people spend a lot of time trying to complete software-related assignments. Poorly designed software can waste both time and resources needed to complete a task. It is therefore important to have efficient ways to complete these tasks. The Swedish Defence Research Agency, also known as FOI has developed software to calculate whether simulated units in the terrain have radio contact or not. In the current approach the employees manu-ally writes scenario files which contains information about the contact. However, these sce-nario files quickly become very large and difficult to work with. A possible solution to this issue is creating a scenario editor where the user can use an interface to create information about the contact between the units. This thesis suggests a Military Combat System Scenario Editor (MCSSE) which is compared to writing scenario files manually. The comparison is made by first performing a number of tasks with both applications. The applications thereafter evaluated using a metric called Minimal Actions Performed (MAP) which is defined for this comparison. The thesis also suggests appropriate tasks for evaluating the applications using an iterative method consisting of meetings with an expert with specified questions. By using the MAP metric, the application can be evaluated and the results show that the MCSSE is on average 66% more efficient than the current approach.
