Hello,

I have needed an equally spaced vehicle flow. As per the documentation
<http://sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes#Repeated_vehicles_.28Flows.29>
,
vehicles should be equally spaced unless someone randomizes the flow. I
didn't randomize the flow, but I am experiencing that the vehicles do not
have the same headway.

Here is my rou.xml file entry, and I set sigma = 0 as well.

<flow id = "f1" color="1,1,1"  begin = "0" type="Car" vehsPerHour="1500"
number="100" route="route0" departSpeed="13.9"> </flow>

I am seeing majority of the vehicles have a headway around 27m and some
other vehicles around 40m. There is a pattern. The first 2 vehicles of
every 5 vehicles travel together (with 27m  heading), and other other 3
travel together (with 27m  heading) but with 40m gap between 3rd and the
2nd (e.g. V represents a vehicle
V**V**V*****V**V*****V**V**V*****V**V**V**V**V*****V**V)

I tried this as well.  <flow id = "f1" color="1,1,1"  begin = "0"
type="Car" period="2.4" number="100" route="route0" departSpeed="13.9">
</flow>

But it is the same as the previous.

Is this is a bug or is there a workaround for this?

Thanks,
Dee.
