Hardin Valley Mobility Study

Knoxville-Knox County Planning and Knox County have partnered to examine existing transportation conditions and future needs in the Hardin Valley area. The study will prioritize improvements with the goal of maintaining mobility and addressing safety for people using different types of transportation.

Hardin Valley is situated in the northwest part of Knox County. As measured by building activity, northwestern Knox County is the fastest growing area of the county. Rising traffic volumes, new schools and continued growth warrant a closer look at area transportation issues.

Existing Traffic

Traffic volumes were collected at 27 major intersections within the Hardin Valley community to assist us in analyzing peak hour congestion levels as well as understanding the complex travel patterns within the study area.

As expected, the data shows us that the highest peak hour volumes are experienced at intersections along, or in close proximity to, Pellissippi Parkway.

Using the map below: Zoom into a particular intersection to view the peak AM and PM traffic counts. Click/tap an intersection for more details.

The AM and PM peak period counts represent the one-hour period of time in the morning and afternoon with the highest total traffic volume entering each particular intersection. The traffic is observed and counted by each movement (left, right, straight through) at the study intersections for a minimum of two hours in each period and tallied in 15-minute intervals with four highest consecutive intervals comprising the peak hour. This data is then used to determine the capacity and level-of-service at each intersection to evaluate its performance with regard to delay and congestion.

Historic Safety

Historic crash data was collected for a 3-year period (January 2015-January 2018) in the Hardin Valley community.

Creating a heat map of these crashes shows that the interchanges along Pellissippi Parkway experienced the most crashes in this time frame.

Land Use

The existing land uses within the Hardin Valley study area are dominated by Agriculture/Forestry/Vacant Land, followed by Rural Residential and Single-Family Residential uses.

Commercial, Office, and Multifamily Residential uses are largely clustered near Pellissippi Parkway and I-40/75 interchanges.

Historic Development

Between July 2014 and July 2018, approximately 1,200 building permits were issued for new construction projects within the Hardin Valley study area.

Roughly 90% were for residential uses and the remaining 10% being all other uses.

About the Study

The project is focused on identifying existing and future transportation facility deficiencies. Transportation improvements that were identified in past studies will be prioritized, and improvements to the road network that address safety, congestion and connections across the area will be recommended. Preliminary cost estimates for 5, 10 and 20-year horizons will then be given. Because the study will focus on travel within Hardin Valley, as well as the major roadways leading to and from it, the study will cover a larger area.

Because the studies will focus on travel within the Hardin Valley, as well as the major roadways leading to and from it, the study will include a larger area.

There are significant topographical constraints in the study area that create mobility and connectivity challenges.

Project Schedule

The project is expected to begin in the summer of 2018 and be completed by the spring of 2019. Data collection activities, such as traffic counts, will begin in the Fall of 2018, when school returns to session.

Meeting Schedule

Community Input

Throughout the project, Planning staff will work to engage citizens, property owners, the business community, and elected officials. Outreach will include:

  • Formation of a steering committee
  • Stakeholder interviews
  • Two public meetings to gather input on the issues in the area and to solicit feedback on project recommendations
  • Online input opportunities
