One artrial splits into two one way street at some intersection and merges back to two way.
So I have one link for the two way arterial, and two one-way link for the one-way arterial.

However, this causes problem when producing arterial report such as travel time. SimTraffic did not recognize the eastbound or westbound arterial.

Is it possible to define arterial in Synchro?

Thanks,

You can get an arterial report for this type of system. You will have to use route numbers. For your links that are two-way, name them "Street Name #1 #2". That means, put in the pound (#) sign with a number designation behind it. For the two-way streets, you'll have 2 number designations.

For the first one-way portion of the street, call it "Street Name #1". The other one-way portion would be "Street Name #2". You can then get an arterial report for route #1 and route #2.

Thanks,

John.
