Re: [sumo-user] speedFactor does not change the speed and travel time

Dear Laura,

I could not see the speed difference because the speedfactor was not working. I 
had defined the speed factor as a vehicle attribute and this was the problem.
I used the “createVehTypeDistribution.py” and generated a series of speed 
factors. Then I used the type generated by this python code in my route file.

Solmaz

Dear Solmaz,

did you have a look in sumo-gui to check whether the vehicle are able to drive 
with a higher speed for a short time or is there maybe a traffic light or other 
vehicles blocking so that the travel time is not chaging?

Best regards,
Laura

Dear all,

I am trying to understand the following sentence in the wiki:

Using speedFactor="normc(1,0.1,0.2,2)" will result in a speed distribution 
where 95% of the vehicles drive between 80% and 120% of the legal speed limit.

Let’s say the legal speed limit is defined as 100 kph in the net file. From 
what I understood, if I increase the first number which is the mean (for 
example from 1 to 2) the speed should be increased to 200% of the legal speed 
limit (200kph) for 95% of the vehicles. The min and max (0.2 and 2 
respectively) make sure the chosen speed is not lower than 20%  (20kph) and 
higher than 200% (200kph) of the legal speed limit.
I tried to change the speed factor to increase the speed and expected lower 
travel time and higher speed. But changing the speed factor does not change the 
travel time at all.
I even used the normal distribution without cut-off. speedFactor="norm(2,0)" 
should increase the speed by 200kph for all vehicles (given that the std is 
zero). But again, there is no change in travel time and speed.

Solmaz

Hi Solmaz,

you should see changes in the travel time. How are you defining the speed 
factor?

I think there are some problems if you use a distribution for speed factor as a 
vehicle attribute, like this:

or



But if you define a vehicle type with the desired speed factor distribution and 
then use this type for the vehicles or flows, it should work:


or
