Origin and destination (OD) matrices are considered as a key point for the transportation and city planners. With
the development of advance transportation technologies installed in the public transit, transportation agencies can
make necessary adjustments and implement dynamic measures much easier. Automated Data Collection (ADC)
systems installed to the vehicles, which are more efficient and economic than other conventional data collection
methods, are especially helpful to store data regarding passengers and their trips. Although the origin of a passenger
be deduced much easier, the challenging part is to detect the passengers’ destination properly, especially for the
bus passengers due to the lack of data when the passenger exits from the system. The objective of this study is to
provide a method for inferring the alighting locations of the bus passengers in order to construct more reliable OD
matrices. This method is tested by conducting a case study for a single bus route in Istanbul. The overall results
show that by using the proposed algorithm over 65% of all recorded trips’ alighting locations were derived. By
excluding instances where boarding information is missing or the same card in repetitively used, the success rate
reaches up to 70%. For future studies it is suggested that unique characteristics of the transportation systems must
be delved into in order to eliminate misleading outputs of any proposed algorithm.
