 Average Annual Daily Traffic (AADT) volumes, as well as morning and afternoon peak hour traffic volumes, were developed for each alternative by DVRPC for the design year (2026) conditions.
The resulting projected traffic volumes for each alternative are summarized below.
No Build Alternative
When comparing the existing traffic volumes with design year (2026) No Build Alternative traffic forecasts, the forecasts indicate an increase in daily traffic volumes from less than 10 percent to more than 90 percent. However, for the Woodhaven Road Project study area, most of the major east-west roads are expected to see an increase in the range of 15 to 30 percent.
Generally, the major east-west routes experience only slightly higher increase than the smaller arterial routes. This indicates that an increase of traffic volumes in the west and northwest part of the Woodhaven Road study area is filtering through multiple routes to access the main highways and thoroughfares in the eastern part of the study area. This is due to the lack of an easy access route with sufficient capacity to the main highways.

Byberry Road Upgrade Alternative
For the Byberry Road Upgrade Alternative, traffic forecasts south of Byberry Road remain virtually the same as the design year (2026) conditions for the No Build Alternative, indicating traffic patterns and volumes in this area are not expected to change as a result of the improvements.
North of Byberry Road, traffic forecasts present a much different picture as traffic increases on County Line Road, Buck Road, Pine Road and on Bustleton Avenue. Daily traffic volumes are expected to increase by about 10 to 20 percent on County Line Road and by nearly 30 percent on Byberry Road when compared to design year (2026) No Build Alternative conditions as a result of the proposed improvements.

Woodhaven Extension Alternative
For the Woodhaven Extension Alternative, traffic forecasts south of Byberry Road and the Woodhaven Extension are close to design year (2026) conditions for the No Build Alternative, except south of Tomlinson Road on Bustleton Avenue and Red Lion Road east of Bustleton Avenue.
As with the Byberry Road Upgrade Alternative, there are increases in traffic volumes north of Byberry Road on County Line Road, Buck Road and Pine Road. However, when compared to the Byberry Road Upgrade Alternative, the Woodhaven Extension Alternative appears to be a more attractive alternative for County Line Road motorists west of the study area. The higher forecasted daily traffic volumes on Pine Road and Buck Road indicates that this alternative becomes an attractive option to staying on County Line Road and Bustleton Avenue.

Bustleton Avenue Alternative
Much like the Woodhaven Extension Alternative, traffic forecasts for the Bustleton Avenue Alternative in the southern area are similar to the design year (2026) conditions for the No Build Alternative except for the area south of Tomlinson Road on Bustleton Avenue, and on Red Lion Road east of Bustleton Avenue. On these two roads, daily traffic is forecasted to decrease, indicating the new roadway becomes a more attractive route to access The Roosevelt Boulevard and other roads south and east of the study area.
Also similar to the other alternatives, north of Byberry Road the traffic volumes increase significantly on County Line Road, Buck Road, Pine Road and Bustleton Avenue. The main difference between this alternative and the three other alternatives is that the forecasted increases in traffic volumes are significantly less on Byberry Road, Pine Road and South Buck Road since the extension ends at Bustleton Avenue. Traffic forecasts on Bustleton Avenue are slightly higher for the Bustleton Avenue Alternative compared to the Woodhaven Extension Alternative.

Bustleton Avenue Alternative Modified
The Bustleton Avenue Alternative Modified is similar to both the Bustleton Avenue Alternative and the Woodhaven Extension Alternative.
When compared to the Bustleton Avenue Alternative, the most notable difference is the projected traffic volume at the intersection of Bustleton Avenue and Byberry Road. At this location, traffic north of the intersection is about the same. However, daily traffic south, east, and west of the intersection drops significantly as the additional roadway provides a more desirable east-west route.
When compared to the Woodhaven Extension Alternative, traffic forecasts for the Bustleton Avenue Alternative Modified are about 30 percent lower on Byberry Road west of the tie-in point. However, there are four lanes on Byberry Road west of this intersection for the Woodhaven Extension Alternative, and only two for the Bustleton Avenue Alternative Modified, thus making the Woodhaven Extension Alternative a more attractive route to motorists.
