Hi Natalia,
both your definitions and the output are correct. The output gives the
total number of vehicles not the average. If all your edges are
consecutive you might want to define the vehicles to run all the edges
to have less insertions. Something like this:

<flow id=“1" type="1" from="1" to=“10" begin="75600" end="79200"
vehsPerHour=“100" departLane="best" departSpeed="max"/>
<flow id=“2" type="1" from=“3" to=“10" begin="75600" end="79200"
vehsPerHour=“80" departLane="best" departSpeed="max"/>
<flow id=“3" type="1" from=“3" to=“4" begin="75600" end="79200"
vehsPerHour="20" departLane="best" departSpeed="max"/>
<flow id=“4" type="1" from=“7" to=“10" begin="75600" end="79200"
vehsPerHour=“50" departLane="best" departSpeed="max"/>
<flow id=“5" type="1" from=“9" to=“10" begin="75600" end="79200"
vehsPerHour=“20" departLane="best" departSpeed="max"/>

Best regards,
Michael
