A Reputation-based Shared Transport System. A Case Study of E-collaboration in the City of Ambato

The governments of cities like Ambato face difficult geographic conditions for establishing a clean and efficient transportation system. This paper shows the results of 1) a theoretical study that measured the expected incidence of a reputationbased shared transportation system for e-collaboration and social welfare in a medium-size community and 2) an experimental evaluation of the effectiveness of a value-based reputation system with malicious user detection in such a scenario of e-collaboration. The study was conducted based on economic savings. The theoretical study involved the participation of 185 young citizens and 160 in the experimental evaluation. The theoretical results show that ecollaboration is meant to be successful in a shared transportation system in Ambato providing that trust is guaranteed. The experiment results show that the proposed model made it possible to detect 85% of malicious service consumers and that the satisfaction with the recommendations of the system is pretty high. These results are encouraging for using the proposed method in the implementation of a shared transport system in medium-size cities. Therefore, it is assumed that the obtained results are extrapolates to the context of a generic e-collaborative system.
