The base model was developed by Parsons Brinkerhoff for the previous phase of the Do-
minion Boulevard/Route 17 improvements project. The following table represents the inter-
section level of service based upon the projected 2034 volumes and the Parsons Brinkerhoff
Synchro model. The signalized intersections that have available turning movement data are
shown in the following table with corresponding LOS as determined by modeling the traf-
fic volumes in Synchro. The LOS of a signalized intersection is based upon the amount of
delay vehicles will experience at the intersection. Intersection LOS ranges from A (free flow)
through F (forced flow-jammed). The goal is to obtain a LOS D or better within the project
area.

Trip Generation
The Institute of Transportation Engineers (ITE) Trip Generation Manual, 9th Edition was
used to calculate the anticipated trips generated from the different land uses proposed
within the 4 areas based on the proposed development plan and are summarized in the
table below. Internal and pass-by trip reduction factors were considered for this develop-
ment. The ITE Trip Generation Manual, 9th edition provides a multi-use development trip
generation and internal capture summary worksheet to assist in calculating the internal
capture rate. The internal capture rates utilized range from 0 percent to 27 percent depend-
ing on the particular area land uses.

*Area 10 is considered as an opportunity area and has only been analyzed for 2.2 million
square feet of industrial space rather than 6.8 million square feet. As development occurs
the impact to the roadway network should be closely monitored. Once the 2.2 million square
feet have been realized, each new development impact should be analyzed, and associated
improvements needed incorporated into the Master transportation plan
