I am not completely clear from your map of the road configuration - are the
three counting stations on different roadways, eg. slip roads onto/off the
single main arterial represented by the axial line? Or are they three
separate counts along the length of that arterial? If the first, then you
should sum them and attribute to the single axial line, if the latter you
should include them separately, or else average them, depending on whether
they are counted at the same times as each other, or reflect different
sampling periods.
