Hi all,
I have encountered a problem since upgrading to SUMO 0.30.0 from 0.29.0. I 
notice that when I use duarouter to create a route file from a flow file and a 
vehicle type file, the speedDev and speedFactor parameters for each vType are 
concatenated like so:

speedFactor=“9.0” speedDev=“0.20” => speedFactor=“(0.90,0.20)”

Running sumo or sumo-gui using the resulting route file throws the following 
error:

Error: value '(0.90,0.20)' does not match any member types of the union
 In file 'test.rou.xml'
 At line/column 23/115.

From the SUMO documentation, I note that the correct syntax for the new 
speedFactor assignment should be:

speedFactor=“norm(0.90,0.20)”

I had to fix the route files by hand to follow this syntax before I was able to 
get them to work as inputs for sumo. Has anyone else encountered this bug, or 
know where in the sumo codebase I could find the source of the error and write 
a patch?
Best,
Walker Dula
