Some of the most important problems arising in public transport, are the effective allcoation of drivers and vehicles. These, so called "Vehicle and Duty Scheduling Problems" are mostly easy to be defined, but hard to be solved to optimality. An important aspect in improving solutions for such problems, is visualizing the problem and the known solutions. Doing so, the structure of solutions can be revealed, and posiiblities to improve them can be discovered. On the other hand, it is also possible to visualize complex algorithms and provide material in terms of movies and images.
