4.2.2 Alternative 1 – Additional Supply
Alternative 1 is based on widening existing roadways to accommodate future traffic and
consists of eight roadway widening projects as indicated on Table 4-1. These eight
projects were coded into the future year model and the model was run to project future
traffic volumes for the study area roadway network. Figure D-1 in Appendix D shows
the changes in the model network associated with this alternative.
Table 4-1: Alternative 1 – Year 2025 Additional Supply
Project Roadway Improvement From To
1-1 SR 434 (Alafaya Trail) 8 Lanes E. Mitchell Hammock Road McCulloch Road
1-2 W. McCulloch Road 4 Lanes Rouse Road SR 434 (Alafaya Trail)
1-3 SR 426 6 Lanes SR 417 (Greenway) Winter Springs Blvd
1-4 SR 434 4 Lanes Mitchell Hammock Road SR 417 (Greenway)
1-5 Lockwood Road 6 Lanes Mitchell Hammock Road CR 419 (E Broadway St)
1-6 Snow Hill Road 4 Lanes CR 419 (Chuluota Road) Langford Road
1-7 Mitchell Hammock Road 6 Lanes SR 426 SR 434 (Alafaya Trail)
1-8 CR 426 4 Lanes Lockwood Road Pine Hills Blvd
The model results were converted to AADT and peak hour/peak direction volumes, and
compared to the future capacities based on the future year number of lanes in the
alternative. A comparison table located at the end of this section, Table 4-2, shows the
resulting future year volumes and peak hour/peak direction LOS for this alternative,
highlighted in blue.
As shown in Table 4-5 there are 17 roadway analysis segments which are projected to
operate deficiently, or worse than their adopted LOS standard, in 2025 with the
proposed widening improvements. Of those 17, 13 are projected to operate at LOS F.
Of those 13, 5 operate worse than LOS F even with improvement. As indicated by the
results of this analysis, even with several widening projects, there is still additional
demand in certain corridors of the system that is not being met.
For example, despite widening much of SR 434 (Alafaya Trail), many of the segments in
this corridor still operate in a deficient condition. This is a strong indication of additional
demand for north/south roadway capacity in this area.
This alternative focused on directly improving failing corridors by adding capacity where
failures exist. However, increasing capacity on major roads also increases the
attractiveness of that road to the automobile driver. Thus, the operating condition of the
roadway does not always improve although capacity is increased. This is due to the
increase in demand as seen in this alternative.
In terms of consistency with the guiding principles this Alternative is somewhat weak.
Guiding principle A and B recommend against the creation of multi-lane highways and
roads greater than 6 lanes. Alternative 1 is inconsistent with both of these
recommendations in that it focuses on creating multiple lane highways where there is
demand regardless of number of lanes. This Alternative is also somewhat inconsistent
with principles C and H, in that it does not contain new connections and encourages
more multi-lane facilities which are frequently not accommodating of bicycle and
pedestrian modes. Figure 4-3 shows the deficient roadways included in this Alternative.
