Spatio-Temporal Traffic Flow Forecasting on a City-Wide Sensor Network

Map matching imprecise trajectories for smart mobility applications

“…The accuracy of the running speed estimates generated by the proposed system is evaluated in terms of the mean absolute error (MAE), in line with the practice followed by several works on traffic condition estimation (e.g. [49], [116] and [148]). In this context, the MAE is simply equal to the average of the absolute differences between the true running speed and the estimated running speed, considering all the road segments in all the trajectories.…”
