Roadway Network

Local governments use our Roadway Network Database to determine traffic concurrency, which is how much growth can occur along a road corridor prior to the road running out of capacity.  To establish traffic concurrency along the roadways TPO has established a level of service standard for each roadway.  This standard was derived from the County’s Comprehensive Plan and the Florida’s Department of Transportation Level of Service Manual.

Each year the County and State goes out and puts traffic tubes along the major roadways within Polk County for a period of two or three days.  These tubes are used to count the number of vehicles that pass over them.  Once the duration is completed, we take the counts and compute them to the County’s peak traffic season to derive the Annual Average Daily Traffic counts.  The counts are then computed to show the Peak Hour/Season volume and Level of Service.  The Roadway Network Database is updated annually.
