Hi all,

I use DFRouter to generate traffic, I have measurement files that include
speed readings. The detector data that I use usually does not split the
data in different vehicle types. Therefore, I have all my vehicle types
stored under one distribution, called "PKW". Next to this, having both cars
and trucks within one distribution also ensures that the occurrence of
trucks within a vehicle flow is also randomized.

When I use the detector speed measurements as departure speed of cars, the
simulation quits with an error on startup, because DFRouter created trucks
with a departure speed that is higher than the maximum speed of trucks. An
alternative to avoid this error is to use the flag "--departspeed max", but
then SUMO will ignore the speeds from the detector measurement files, right?

So I hope that a solution will be implemented which uses the detector
readings for the depart speed of vehicles, but with automatic fixes for the
maximum speed of vehicles. The actual vehicle types are decided when
running SUMO or SUMO-GUI, so on the moment of insertion the maximum of the
stored speed and the vehicle's maximum speed should be taken instead of
quitting with an error.

Best regards,
Pieter
