                                                ABSTRACT

                    The present paper deals with the Object Oriented designing through Unified
                    Modeling Language (UML) for a Traveler Management System (TMS). The
                    main aim of this paper is to provide a flexible and faithful environment for
                    traveler, which wants to travel to see the sight scenes, shopping for business
                    meetings, etc. The TMS provides the information to the traveler without
                    losing the time when it needed & the system gives the proper and accurate
                    information to the traveler. The proposed model is based upon the knowledge
                    based system & the complete booking process of a Taxi is defined in this
                    paper and the knowledge model is tested with different data sets. The model
                    also suggests to the traveler that which Taxi will be suitable according as per
                    the budget constraints. In this paper the UML Class, Sequence diagram,
                    Activity diagram & Use Case diagram are also designed for the TMS.
