the new AvFlowEfficiencyCalculator allows the Flow Efficiency of avs with different automation levels to be set, and for these flow efficiencies to change based on the type of road the av is driving on.
The modes implemented are car, prav3, prav4, and prav5. The road types implemented are motorway, trunk, secondary fast, and secondary slow.
Currently car and prav3 have the same PCUs. (Flow Efficiency = 1/PCU) and prav4 and prav5 have the same PCUs.
