Query: Proposal of a Carsharing System to Improve Urban Mobility   Carsharing is a model of renting vehicles for short periods of time, where
the payment is made according to the time and distance effectively traveled.
Carsharing offers a simple, economical and smart alternative to urban mobility,
that is already being adopted in the major cities in the world. The proposed
methodology consisted in the development of a decision support system that
simplifies the process of choosing carsharing services. Adopting the AHP
method, the user can indicate their preferences in the choice of vehicles, and
the system returns an ordered list of the most suitable available vehicles
based on their geographic location. The findings of the project indicate that
the use of this system encourage and simplify the use of carsharing services,
which will allow to enhance the financial, mobility and environment advantages
inherent to their use.
