“…Bus speed/arrival time prediction has been studied widely [9,12,17]. Some researchers focus on the travel time/speed of all links between two bus stops [13,23], assuming the homogeneity between each link.…”

“…This assumption can be easily violated due to different traffic conditions, road designs, etc. Furthermore, considering the segmentation of traffic flow by traffic signals, some researchers divide road segments based on signalized intersections [6,9]. This segmentation method includes regular bus traveling, dwell at bus stops, and unexpected stoppages into the travel speed/time.…”

“…In light of the propagation of congestion and the disturbance caused by traffic incidents, bus speeds can be both spatially and temporally correlated. The investigation of spatial and temporal effects in bus travel speed/time is gaining increasing attention recently [6,[9][10][11]. However, most existing studies address the spatial and temporal effects separately without modeling the spatiotemporal interaction (STI) effects [12].…”

This study proposes a novel Bayesian hierarchical approach for online bus speed prediction by explicitly accounting for the spatiotemporal interaction (STI) of speed observations. The use of Laplace approximation can expedite the estimation of Bayesian models and enable the implementation of online prediction. Large numbers of trials are carried out to identify significant predictors and the optimal length of the look-back time window to achieve the highest prediction accuracy. The spatiotemporal interacting patterns are also explored, and results show that the Type IV model assuming the structured spatial effect interacts with the structured temporal effect can best accommodate the bus speed data. Besides, prediction errors of the Type IV model randomly distribute over time and space. The proposed model can achieve high prediction accuracy and computational efficiency without compromising the interpretability of the contributing factors and the unobserved spatiotemporal heterogeneity. The proposed model can be used to assist public transit operation and management, such as bus scheduling, congestion warning, and the development of proactive measures to mitigate bus delays.

Accurate prediction of bus arrival times is a challenging problem in the public transportation field. Previous studies have shown that to improve prediction accuracy, more heterogeneous measurements provide better results. So what other factors should be added into the prediction model? Traditional prediction methods mainly use the arrival time and the distance between stations, but do not make full use of dynamic factors such as passenger number, dwell time, bus driving efficiency, etc. We propose a novel approach that takes full advantage of dynamic factors. Our approach is based on a Recurrent Neural Network (RNN). The experimental results indicate that a variety of prediction algorithms (such as Support Vector Machine, Kalman filter, Multilayer Perceptron, and RNN) have significantly improved performance after using dynamic factors. Further, we introduce RNN with an attention mechanism to adaptively select the most relevant input factors. Experiments demonstrate that the prediction accuracy of RNN with an attention mechanism is better than RNN with no attention mechanism when there are heterogeneous input factors. The experimental results show the superior performances of our approach on the data set provided by Jinan Public Transportation Corporation.
