DATA PROCESSING SOFTWARE FOR AN AUTOMATIC DATA ACQUISITION SYSTEM IN MASS TRANSIT

Volumes of raw data collected using the Automatic Data Acquisition System are useless until they can be processed and transformed into meaningful reports and plots. This is done using the data processing software. The software has a matching algorithm that is modular in structure. It uses a simple, systematic, and logical sequence of actions in attempting to match the recorded activities in the raw data file to actual bus stops. The algorithm is tested, validated and justified by performing sensitivity analyses on data files resembling those obtained from the Automatic Passenger Counter experiment conducted in Roanoke Valley Metro in Virginia. It is found that the algorithm does not change its matching process with changes in the system variables. Thus, a robust algorithm has now been developed to do the matching accurately, removing the need for a radio signpost signal to be embedded to establish locational accuracy, consequently eliminating signpost installation and maintenance worries and costs.
