1
Storage lengths are taken from Synchro models. These lengtht are not considered in Synchro's queuing and level of service calculations
2
The 50th percentile queue is the maximum back of queue on a typical cycle.
3
Splits and offsets were optimized.
~ Volume exceeds capacity, queue is theoretically infinite. Queue shown is maximum after two cycles.

Note 1: Capacity per lane is from the TPB Versison 2.2 Model. It is the capacity of a through lane.
Note 2: Volumes used are from the interesection analysis that has been post processed.
Note 3: In an urban environment, such as the Dulles Corridor Study area, the capacity of the road system will be determined by the intersection. These numbers
should be used and evaluated with the intersection analysis, shown in Section 4.4. of the Dulles CorridorTransportation Study and Appendix Attachment #1.
