This extended abstract shortly summarizes the work in [2] a prototype of ComeWithMe, an innovative carpooling service oriented to the passenger's intended activity. This approach boosts the number of available rides, di erently from the current carpooling system based on xed destination location. The ComeWithMe ride search engine was modeled to support scalability constraints through an inverted index. Furthermore, a ranking model orders the possible retrieved riders according to the convenience of the passenger.
