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.
