John Hi,

I am trying to find out what the volume is that is leaving my corridor. I go into SimTraffic report and choose the performance report by approach and I look at the final node and see that my NB Vehicles Entered = 3510 and my NB Vehicles Exited = 3512, which looks good, but when I review my input into Synchro I have only 1921 NB vehicles/hour entering the intersection.
I ran the simulation for a 10 minute seeding and a 1 hour recording. Why are my entering and exiting volumes so High???

Hi Pat,

Are there a lot of vehicles at the upstream intersection? That is, a large sink that is created bewteen the two due to volume inbalance? This would be my guess. If that is the case, the sink vehicles get reported at your downstream intersection.

Thanks,

John.
