Abstract
A robust algorithm has been developed to do data processing accurately, removing the need for a radio signal to be imbedded for locational accuracy. This, consequently eliminates the signposts installation and maintenance costs and worries. A sensitivity analysis of the algorithm using a real life data file revealed that the matching process change with changes in system parameters, adding credibility to the technique used for matching in the algorithm.

Next, several new programs have been added to bring together a software package yielding management reports and plots. These reports and plots are tremendous decision aiding tools and since the programs are interactive, the package is easy to use. A user’s manual has also been developed.

Finally, an implementation of the Automated Data Acquisition System at TRT, Norfolk, is discussed. A systematic approach to the software development to meet the needs of the transit property has been conceptualized and specific software developed. A discussion of the details of this software development has been addressed, too.

In essence, Automatic Data Acquisition systems research at Virginia Tech has now evolved to such a stage that with a little "tuning" of hardware & the associated software, a very powerful and versatile automated data collection and management aiding tool will be available for economical widespread implementation.
