The Transportation Information System was developed as a tool to perform specific tasks relating to transportation data. Since its initial development, TIS has undergone many modifications and additions in order to meet new or changing demands. TIS has succeeded in meeting its original goals and in satisfying many new demands. But as new demands continue to mount, certain deficiencies in TIS are becoming apparent which will cause increasing difficulties in the future. Because system documentation and standards for system maintenance are inadequate, modifications and corrections to the system are time consuming and difficult. Therefore, some users have created their own data files and stand-alone systems, thus duplicating effort and creating data redundancy and inaccuracy.
Because of the deficiencies of TIS, a Feasibility Study was initiated to research and analyze various alternative methods of resolving the shortcomings of TIS.
