Up to this point, the ClearviewHwy development and
research has been focused on guide signs and the typographic display
of destination names in mixed case. Because ClearviewHwy mixed case
tested more effective than all uppercase FHWA Standard Alphabet legends,
it is recommended that use of ClearviewHwy be explored for regulatory,
warning, work zone, and motorist services signing as well as guide
signs. With many regulatory signs having similar appearance, but
different content, the variation in word pattern may prove to aid
overall legibility and understanding. This may not be a one-for-one
change out and as stated in the original intent of the project, with
some type sizes in the Standard Highway Signs book enlarged or reduced
based on application. It would be ideal if the multitude of panel
sizes could be reduced to a finite series of sizes for commonly used
regulatory signs. This process could reduce cost, provide more modularity
to the system, and improve the visual ordering of sign assemblies
that include multiple panels. This would necessitate a comprehensive
analysis of reading and reaction time requirements for each type
of sign as well as a careful determination of optimal panel sizes
for urban applications where use of the smallest possible size sign
is important.
With the development of a comprehensive family of weights for both
positive and negative contrast within the ClearviewHwy Type System,
it is quite possible that improvements in legibility and ease of understanding
could be realized for regulatory, warning, work zone, and motorist
services signing. To illustrate the options, a small, but representative
sample of signs are shown below in both the current format as specified
in the 2000 Standard Highway Signs book, and with ClearviewHwy type
in a selective use of mixed case. These are shown as a concept, and
are not intended for application.
