Complete Set of Plots

First, a short overview of the information you can find in the plots and how they are represented:
ValueRepresentation
Reception Power: XY Plot - Avg/DistanceBin - Power Distribution (PDF or BoxWhisker)
Reception Rate: Avg/DistanceBin
Packet Inter Arrival Time: BoxWhisker

Links to the plots, grouped by aggregation level:

Single run statistics:
In some plots, a green box shows the LOS area (if TxDistance is greater 0).
XY Plot - Power and Rate (plots are accompanied by color coded map visualization)
XY Plot - Power Over Time - Detailed

Reception Power - Single Runs (Geometric)
Reception Rate - Single Runs (Geometric)

Reception Power Distribution - Single Runs
Reception Power Distribution - Box Whisker - Single Run (plots are accompanied by color coded map visualization)

Street level aggregated:
For each transmitter position, the back and forth run has been averaged. Except when heading wise overlaid, these results should be drive direction independent.
Reception Power - Average per Street (Geometric)
Reception Rate - Average per Street (Geometric)

Reception Power - Average per Street - LOS Only (Geometric)

Intersection aggregated:
For each transmitter to center distance, the results from the different street legs in an intersection have been averaged. Averaging has been done over result curves from single runs (and not by combining all data points) to ensure fair weighting. The only exception are the power distribution plots showing fading.
Reception Power - Average per Intersection
Reception Rate - Average per Intersection

Reception Power - Average per Intersection - Distance Normalized

Reception Power Distribution - Avg Per Intersection
Reception Power Distribution - Avg per Intersection - Centered To Average
Reception Power Distribution - BoxWhisker - Avg Per Intersection

Reception - Packet Inter-Arrival Time - Avg Per Intersection

The plots in this figures are from intersection 2,3,9,10,11,20,21 and 100.
We excluded intersection 1, as we tested 4 TxRate/TxPower combinations in each second (via switching). In consequence, there are gaps (in the distance space) in the data for one configuration. This leads to instability with the used small distance bin length and prevents a proper comparison to the other intersections.
Remember that 9 and 100 are special cases with 9 missing reflection facades and 100 being the free-space test.
