I just started to use Synchro 6 and found it gave total different results from the SimTraffic 5.
1. A very simple fully-actuated signalzed intersection. SimTraffic 5 and 6 gave total different queue results.
2. I coded a free way merge area in Synchro 5 and 6. Simtraffic 5 showed a lot of congestion and SimTrafifc 6 did show any congestion which is consistent with Corsim. Does this mean SimTraffic model freeway better than SimTraffic 5?
Thanks!

Hi,

I would expect Synchro 6 to give different measures then V5. The reasons are fairly numerous. It would be best to go to the "What's New In Version 6" for a summary. The details will be linked in the Help file. The biggest two differences would be queue interactions and revised calculations of d2.

Yes, there has been some tweaking of the simulation lane changing logic. The user can also change the lane changing distances on a link by link basis and this may provide for better simulations.
