ROADWAY SEGMENT EVALUATION – EXISTING CONDITIONS
The roadway segment evaluation consisted of the following:
A review of historical Annual Average Daily Traffic (AADT) data
Level of service (LOS) determination based on daily traffic volumes
Level of service determination based on peak hour and concurrency data
Historical Traffic Data
The purpose of reviewing historical data was to identify trends in traffic volume growth and fluctuation.
This analysis helps to identify the roadways (and roadway segments) within the study area that have
experienced increases/decreases in traffic volume. Table 1 provides a summary of historical AADT data
available from the FDOT database. Overall, historical data shows traffic volumes on the one-way segment
of SR 60 have remained relatively constant over the last 10 years. While historical traffic data are limited
on the primary minor streets within the study area, the trends for the available data are similar to that of
SR 60.
