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.
