»Safer shortest paths through ordinal optimization«

Abstract:
Ordinal costs can be used to model the quality of objects wrt. ordered categories whenever numerical (cost) values are not available. For example, the safety of a street segment can be ranked in ordered categories like safe, medium safe, and unsafe. We particularly focus on applications in pedestrian routing and consider the case of optimizing paths for children on their way to elementary school. We discuss the interrelation between ordinal optimization and associated multiobjective problem formulations at the particular case of shortest path problems. Modeling aspects with regard to consistency of preference choices and wrt. the avoidance of safe, yet overly long paths, are discussed. Associated solution concepts are suggested, and the problem is illustrated at a small instance in the city of Wuppertal.
