At their last meeting, the Leon County Commission accepted the Concurrency Annual Report for 2018. One of the main purposes of the report is to evaluate the Level of Service (LOS) standards for roadways.
LOS definitions are provided below.
The report indicates that of the 444 roadway segments monitored, there were 21 roadway segments operating below the minimum required LOS. These 21 roadway segments are operating at 100% volume to capacity ratio or greater, and, are therefore exceeding the LOS adopted in the Tallahassee-Leon County Comprehensive Plan.
Eleven of the twenty-one segments that are operating below the adopted LOS are state roads. One of the state road segments, North Monroe Street from Sessions to Fred George Road, is capacity constrained. This segment cannot be widened further due to prohibitively costly right-of- way.
The remaining ten segments are Leon County roads.
Eight of the ten Leon County road segments are operating below the LOS standard are based on projected demand, not trips currently on the road.
The report provided assessments of three of the capacity challenged segments.
Buck Lake Road from Mahan Drive to Vermillion Boulevard is over-capacity in both directions based on reserved trips from nearby residential and commercial development. Widening this segment of Buck Lake Road is prohibitively expensive.
Miccosukee Road westbound from Dempsey Mayo Road to Fleischmann Road is a constrained Canopy Road, with reserved trips from nearby residential and commercial development. The Northeast Gateway project will relieve congestion on Miccosukee Road by constructing Welaunee Boulevard South (Fleischmann Road to Interstate 10) and Welaunee Boulevard North (I-10 to Shamrock Way).
Old Bainbridge Road northbound from Fred George to Capital Circle is exceeding the LOS standard based on the traffic count. There are planned safety improvement for lane striping, more visible signage, and increased shoulder width (without impacting the tree canopy) in the next Florida Department of Transportation Fiscal Year. Old Bainbridge Road is a constrained Canopy Road. Canopy roads cannot be widened due to negative environmental impacts.
Roadway Segments Exceeding the LOS Standard in Leon County
LOS ‘A’ – The highest quality of traffic service; motorists are able to travel at their desired speed.
LOS ‘B’ – Similar to LOS ‘A,’ although the presence of other vehicles becomes noticeable.
LOS ‘C’ – The influence of increased traffic density becomes marked. The ability to maneuver within the traffic stream is affected by the presence of other vehicles.
LOS ‘D’ – The traffic flow is unstable and the ability to maneuver is severely restricted due to traffic congestion. Travel speed is reduced by the increasing volume.
LOS ‘E’ – The road is operating at or near the design capacity of the road. Disruptions in the traffic flow are not readily dissipated and regression to LOS ‘F’ occurs frequently.
LOS ‘F’ – The road is heavily congested with traffic demand exceeding the design capacity of the road.
