Fig. 6: Comparison of the true and forecasted data for the I-5 and LA network.
From: Data-driven analysis and forecasting of highway traffic dynamics
a, b Raw data collected from PeMs for the I-10E and southern California network. The data was collected for a week and 5 days respectively. The I-10 highway seems to be mostly congested throughout the week until Sunday. As expected, all highways within the network seem to be congested on the days leading up to Christmas eve (12/21–12/22). Interestingly, there appears to be drastic relief in congestion during and after the actual holiday dates of 12/24–12/26. c, d Forecasted data generated by the MH-HDMD utilizing the last 15 min of data to forecast the next 15 min. The network was forecasted by concatenating data obtained for individual highways and applying the MH-HDMD algorithm to the concatenated data. By visual inspection alone the raw and forecasted data sets are indistinguishable, indicating an accurate forecast. Nevertheless, there is some error present within our forecasts which can be referenced in Fig. 7. The source data underlying Fig. 7a, b are provided in the Source Data file.
