hello,

What is a typical length of Seeding Interval that one should be using for a 60-minute simulation?

I was under the impression that it was sufficient to allow enough time for a vehicle to fully traverse the network. This would depend on the size of the network, of course.

For a small network, is it appropriate to set the Seeding Interval to 60 minutes? When I do this, I get very different SimTraffic results
than when I set it to 5 or 10 mintues.

Any thoughts would be helpful!

thanks
Dave

Hi Dave,

I think the best thing to do is point you to a FHWA resource. They have developed a Traffic Analysis Toolbox that is located at:

http://ops.fhwa.dot.gov/Travel/Traffic_Analysis_Tools/traffic_analysis_toolbox.htm

You'll want to look at volume 3, although all three volumes are very informing. In volume 3, appendix C is relavent to this discussion.

Thanks,

John.
