Smart card data in public transportation provides valuable information on passenger movements. While typically limited to entry transactions, it can be enhanced by algorithms to estimate alighting points and reconstruct origin-destination routes. This allows to calculate key performance indicators such as passenger-kilometers, occupancy rates and schedule adherence, which are essential for daily management and strategic planning of transport networks. In this context, destination estimation plays a critical role in obtaining a comprehensive view of passenger journeys. Over time, significant improvements have been made to destination estimation tools, particularly by incorporating criteria that use historical passenger transaction data, along with those based on stop sequences. These advancements have increased the number of destinations estimated. However, the probabilistic nature of some criteria, due to missing information for certain trips, can introduce biases into the results. To overcome these limitations, an enhanced destination estimation model is proposed. It combines traditional criteria with an optimized version of the "weighted random sampling" (WRS) criterion, leveraging both the transaction historical data and some external counting data. This approach aims to improve the accuracy and reliability of estimations, especially for complex trips. A detailed description of the WRS method will be presented in the submitted short paper.
