C: Facility Type
C1: Context
Context of the roadway—whether urban or rural—plays a role
in determining the most effective deployment strategy. For
example, corridors in urban areas may require a more
significant level of deployment based on the volume and
congestion more likely experienced in these areas (see
Appendix for map).
C2: Functional Classification
Functional classification is a traditional method for
departments of transportation to categorize roadways based
on traditional operational characteristics. Understanding the
classification of a roadway can highlight the role that it plays in
the system and help overall prioritization of deployment. The
level of access control is also considered in this category.
D: Weather
D1: Weather Sensitive
During extreme weather events, transportation operations and
motorist safety can be compromised. Weather conditions that
may have a higher impact on the traveling public require a
specific mitigation strategies and tools. For example, flood
hazard areas and tornado-prone areas may require expanded
TSMO deployment to better manage impacts from extreme
weather events. Tornado activity is shown in this section;
additional statewide and regional tornado and flood hazard
maps are shown in the Appendix.
D2: Hurricane Evacuation Routes
Major corridors that allow rapid travel from the coasts inland
are identified in hurricane-prone areas and are designated as
Hurricane Evacuation Routes (map from ALDOT). These
corridors are likely candidates for high device deployment
density to best serve critical operations and safety in the case
of an extreme weather event. It is anticipated that these
devices will support corridor management systems such as
contraflow, reversible lanes, or other unique strategies based
on the specific need.
