The hourly average speed performance comparison between my output and current PeMS system on GP lane is shown below. (HOV lane data is sparse) The findings are listed below
volume_sum
and occupancy_avg
. If there is no data for the two columns, speed would consider as null. I assume if the detector is not working, there will be no values for both. In that case, would it be more accurate than using detector status as Boolean values to filter out the data?
Next steps on this: @thehanggit to do additional analysis/comparisons, but waiting on comparison data to be brought over from the old PeMS system. Per @pingpingxiu-DOT-ca-gov that data should come early next week.
This issue follows on #386 to check generated speed data quality for the clearinghouse model
int_clearninghouse__detector_g_factor_based_speed
.The goal is to ensure that the developed speed algorithm aligns with the current PeMS system to some extent.
