Aggregating judgments in non negotiable group decisions in transport systems

This paper aims to assess user preferences on four different bus lines connecting Benevento to Rome. For this purpose, pairwise comparison methods were used. Passengers were asked to compare possible alternatives of choice based on three service-related criteria and in a scenario where negotiation is not possible. To understand which bus line was preferred by the users, an aggregation method was used to identify the overall priority vector, thanks to suitable weights assigned to each decision maker and based on congruence with the judgments of all other users.
