Hi everyone,
I need to measure the density and average speed of vehicles for a certain link in my road network. I am using VISSIM 10 and COM interface with Python. The following piece of code works for VISSIM 5 and now I am trying to find an alternative that works for VISSIM 10.
density = link.GetSegmentResult("DENSITY", 0, 0, 1, 0)
speed = link.GetSegmentResult("SPEED", 0, 0, 1, 0)
As I check the COM library, I couldn't find "density" and "speed" attributes associated with a link, so I am confused on how to get them.
Thanks in advance for any help or suggestions.
Hello Ms./Mr. Yuan,
The following code works for Vissim 9 to access the average speed of a certrain link. You can probably try whether it also works for Vissim 10.
"Vissim.Net.Links.ItemByKey(ID).AttValue('Concatenate:LinkEvalSegs\Speed(Current, Current, All)')";
Best regards
