Consider changing the phase order at Node 13: Int
Node #13 Phase:5 NBL, Change to a lagging phase.
Total Delay is reduced by 7793 vehicle seconds per hour!
Node #4 Intersection delay is reduced by 3294 veh-s/hr!
Node #4 WBL Delay is reduced from 46.9 to 45.3 seconds per vehicle!
Node #4 SBT Delay is reduced from 38.8 to 37.9 seconds per vehicle!
Node #12 Intersection delay is reduced by 6872 veh-s/hr!
Node #12 WBT Delay is reduced from 15.7 to 4.4 seconds per vehicle!
Node #13 NBL Delay is reduced from 44.6 to 40.1 seconds per vehicle!
Node #36 EBT Delay is reduced from 23.4 to 21.8 seconds per vehicle!
Node #39 EBT Delay is reduced from 6.4 to 5.6 seconds per vehicle!
Node #146 EBT Delay is reduced from 15.8 to 15.1 seconds per vehicle!
Node #151 NBT Delay is reduced from 20.2 to 18.6 seconds per vehicle!

To optimize phase orders:
   Check the "Optimize Lead/Lag Phasing" option AND
   Set "Allow Lead/Lag Optimize" to YES in the Phasing window.
Performing a complete Lead/Lag optimize may find even greater
   timing improvements.
Combining these suggestions may reduce total delay more or less than
   the sum of the improvements.
WARNING, Permitted left turns should not be used with lagging left turns.
All delays listed above are uniform delays only.  The incremental
   portion of delay is not affected by offset optimization.
