In a four legged intersection, if one of the approach (lets say the west approach) is one-way towards the intersection (eastbound direction), why can't I code the opposite approach as a shared westbound left and right turn lane? Currently Synchro only lets you put in a separate lane for left and right turns. If there is a way to code it please let me know.

Thanks.

Hi JK,

In this case, code the WB with a WBT and a shared left and right lane. Do not code a WBT volume. Synchro and SimTraffic will then ignore (not place) a downstream WB receiving lane.

Hi John,

I am facing exactly the same problem. Coding WB approach with a WBT and shared WBL and WBR lane wouldn't produce LOS for individual WBR and WBL movements. Any suggestion?

Thanks.

Hi MRT,

If you code the WBR and WBL shared, they will be considered a lane group and will only get one delay and LOS. If they are coded as separate lanes, then you get a delay/LOS for both movements.

Thanks,

John.
