I've coded a dual left turn lane in Synchro to have 400' of storage. When I run SimTraffic, the storage lanes are only holding 8 vehicles in each lane (passenger, 16' long, 5' spacing). There is a lot of spillback as a result. How can I get SimTraffic to accuratly refect the proper storage length? thanks!

Hi Derrick,

Are you getting any warning messages when you do this? I can think of two things that would cause this:

* You link that the storage pocket is on is less then 400'. For instance, you have a bend node on the link.

* The intersection in question has a very large width caused by an acute angle. Large intersection create large spaces and will start to reduce the amount of available storage. In cases like this, you might get a warning about the angle of your intersections.

If that doesn't seem to explain it, please send us the Synchro file and we'll be happy to investigate.

Thanks,

John.
