Faculty Civil Engineering and Geosciences Department Transport & Planning Date 2014-06-04 Abstract Bus travel times are subject to inherent and recurrent uncertainties. A real-time prediction scheme regarding how the transit system evolves will potentially facilitate more adaptive operations as well as more adaptive passengers’ decisions. This scheme should be tractable, sufficiently fast and reliable to be used in real time applications. For this purpose, a heuristic hybrid scheme for departure time estimation is proposed in this study. The predic-tion generated by the proposed hybrid scheme consists of three travel time components: schedule, instantaneous and historical data sources. Genetic algorithm is applied in order to specify the contribution of each data source component to the prediction scheme. The pro-posed scheme was applied for a trunk bus line in Stockholm, Sweden. In addition, the current-ly deployed scheme was replicated in order to compare the performance of both schemes. The results suggest that the proposed scheme reduces the overall mean absolute error by almost 20%. Moreover the proposed scheme provides better predictions except for very long term predictions where both schemes yield the same performance.
