Speed and Road Configuration
Dominion Boulevard is an Urban Principal Arterial maintained by the City of Chesapeake.
The speed limit along Dominion Boulevard is posted at 45 miles per hour (mph) south of
Cedar Road through most of the study area. Dominion Boulevard currently has three (3) sig-
nalized intersections and one (1) unsignalized intersection in the study area. They include:
Dominion Boulevard and Cedar Road/Moses Grandy Trail

Existing Traffic Volumes
The Average Daily Traffic (ADT) volumes for the study area were provided by the City of
Chesapeake and obtained from other publicly available sources. No traffic counts were
done in conjunction with this study. Background traffic data is shown in the following table.
The traffic volumes were grown to the current year 2014 utilizing a 3 percent growth rate per
year and grown 1 percent per year to the 2034 studied year, which was provided by the City
of Chesapeake Traffic Engineering Department.

The ADT volumes are slightly higher on the northern end of the study area, since some
development has already occurred around Cahoon Parkway, Grassfield Parkway, and
Scenic Parkway. A residential development is located off of Cahoon Parkway along with
Cedar Road Elementary School. Development along Grassfield Parkway consists of a Wal-
Mart, Applebee’s, and a few other retail stores. Grassfield High School is located along
Scenic Parkway.
Existing Level of Service
According to the Highway Capacity Manual 2010, a two-lane highway operates at an
acceptable capacity at 3,200 passenger cars per hour (pc/h) for two directions. Multilane
highways with flow rates over 1,400 passenger cars per hour per lane (pc/h/ln) result in
speeds below the highways free flow speed. Level of Service (LOS) is used to categorize
the segments of the corridors. LOS ranges from A through F and is determined by the
density along the roadway. A roadway with a higher density will cause the free flow speed
to decrease which will lower the LOS. The table below describes the existing level of service
based on density for the corridors located in the study area.
