Abstract
ThegrowingmobilityproblembetweendifferentpointsinthecityandtheInstitutoSuperiorTe´cnico(IST)
campi portraits the shuttle service as one of the most important solutions for current difficulties. It also
posesnewchallengesrelatedtoticketing,fraud-evasionandeffectivecost-wisetransportationservices.
ISTprovidesitscommunityafreeshuttleservicebetweenTagusparkandAlamedaCampiandother
keypointsofthecityensuredbyanoutsourcedvehicleservice. Thisshuttlehasseveralstaticpredefined
routes, stops and schedules. All the management is done manually in a tedious and non-optimal way,
not allowing the shuttle to effectively surpass its passengers necessities in real-time. Moreover, there
arequiteoftenproblemswiththeseatoccupationleadingtoeitheroverorunder-crowdingofthevehicle.
This work proposes a dynamic and real-time Booking, Management and Monitoring (BMM) service
for the IST shuttle service. Members of the community can access, in real-time, the central platform to
